Dr. James Canton is a future technology advisor and CEO of the Institute for Global Futures. As mentioned at https://globalfuturist.com/about/the-igf-team/dr-james-canton, “he has advised three White House Administrations and over 100 companies” (cf. advisor at the interagency working group on nanotechnology at NSF during Clinton and Bush Presidencies).
Transcript: "I want to take a look at less on the technologies, more on the capabilities and try to answer the question of who might be interested and why, what is the upside and for who. Next slide please. I run a think-tank, the Institute for Global futures. We do one thing mostly for corporations around the world and governments. To look at what are our strategic readiness factors. How do we define that. What does that model look like. We look at a variety of different kinds of technologies. I'll break down five today but focus on neurotechnology. And our mission, really is to enhance future readiness, so I'm going to put together two concepts and then come back to this and reiterate it.
Lack of imagination is the enemy of future readiness. And those of us who are involved in deterrence, strategic awareness know the implications of that. Is it possible that neurotechnology could be a candidate for a new threat domain or contributed to a new threat domain for all intents and purposes that their only enemy might be a lack of imagination. (Refers to slide:) Worldwide clients, a lot of them are in the room today.
So I'd like to start out by thanking SOFWERX for inviting me and just to suggest to you that I've been working with the community in identifying a variety of technologies over a fairly long period of time and I'm still on this journey. Also I'd like to just call out Dr. Giordano who gave you an opportunity to work with him at the Center for Neurotechnology and Potomac Institute where we started to do some of this work. So I'm gonna frame out for you kind of the big picture of what neurotechnology looks like, to give you, those who are not that aware of that (an idea). We've been focusing a bit more on the particular incident in Cuba and the analogous implications for other attacks that might have a signal similar signature. But really what I'm going to do is try to paint a picture of where this technology has been, where we think it's going and also then drill down on this particular event.
https://youtu.be/TzHj8KQfD7o?t=160 So this is a model that came out of some work that was supported by the National Science Foundation (NSF) and it was work that was done over the past decade to kind of consider what are the top technologies, that are exponential technologies, that are game-changers. Meaning for our civilization. That would affect everything from healthcare, to defense, to manufacturing you know what does it look like. And the top technologies we identified were nano, bio, IT and neuro. And then subsequently, I upgraded this model and added quantum as another strategic technology that would create a massive amount of opportunities. Now, every one of these five technology buckets has dual use. So for all intents and purposes, we focus almost exclusively at NSF in our study on converging technologies for improving human performance but we recognized also that there was a dark side. Dual use technology has followed us throughout. So I'll talk a little bit more about that. But just to define that so we can move on, it's the manipulation of really, genes, atoms, neurons, bits and now qubits that will shape the next, likely, decades, if not a hundred years plus of our civilization. And there's other ones that you can fold into this. The one I'll be focusing on, talking more about is neurotechnology.
https://youtu.be/TzHj8KQfD7o?t=245 Convergence of exponential technologies, certainly the rise of neurotechnology has had a broad effect on many other areas other than just medicine. And for all intents and purposes, the one area that quite frankly that has not been affected has been in security and defense. For all types of purposes we've been looking at innovations, for instance neural nets, where at the core of artificial intelligence, control and monitor over a trillion dollars worth of financial trading for instance. Neural modeling and technology has a massive impact on chip spaces. Let me, can you take me back a couple slides, right there. I want to just make a point about this. The singular scientific piece of this that is published, that we published is a thought that I did not convey but I just want to suggest you. It is not just that nanotechnology, the manipulation of matter at the atomic level or the mapping of the human genome or the ability to be able to create a new computing platform - and in quantum computing it is important - it's how you think about these together, nano, bio, IT, neurons, quantum. And that's been the big “aha” in doing the scientific modeling work. Why? Because most of the time and if you look at how we've organized these bodies of work, whether it's nanotechnology or neurotechnology or IT is they're silos. You've got folks that really get computers quite frankly who are working even adapting innovations never talked to neuroscientists. Neuroscientists are not engaged with nanotechnologists, who are at kind of an engineering mashup. Biotechnologists who are working now, there is a few crossovers like synthetic biology at the beginning of this convergence, but the idea we were suggesting is if we're going to create and solve big problems that are facing our nation, whether they're national security or health care in terms of disease or manufacturing futures. What do we have to do? We got to think more holistically about the system's approach to science and here are the five key technologies, we could have chosen other ones but these are the big strategic ones. So thinking about these together requires a different way of looking at science. And that implication is dramatic for where we are today with neurotechnology but also it has to do with the breakthroughs that would need to occur in healthcare and security, certainly defense and other domains as well.
https://youtu.be/TzHj8KQfD7o?t=404 So let me talk about the big context therefore ok if you're traveling with me on this journey, right. I'm gonna get to our focus. So I'm gonna now kind of pivot a little bit focusing on the trends that are associated with neurotechnology, then go after this particular event and what the implications may be. So the first is that we're all living in Moore's law. And most of the times when you think about Moore's law, again as you know this was the one of the founders of Intel, basically, his hypothesis was that computer technology was doubling in power originally in 18 months. We've brought that down, it’s actually collapsed, so it's less than 12 months. And that same period of time Moore said that, you know, the cost of that technology power was also being halved. So when I was at Apple Computer we spent, it was $2,300 to bring out the first Macintosh. And you know it's a little black and white screen, you know, and 30 Megahertz and it was a box and wow what does $2,300 get you today? Supercomputer, most of you carry them in there in your backpack. Right. So we're talking now about and no one's used this word before neuro-Moore's law. And you heard Dr. Balaban talk about these devices, he's absolutely right. You know this is not rocket science, we're not. This is all about Moore's law: shrinking smaller more powerful devices. So I'm not going to prosecute the “hey, maybe this is some exotic technology', maybe it is but maybe it actually is (that) somebody hacked some pest control devices and they wove it together and then somebody else looked at that as an example and they put something else together, right. So I mean, if you want to cut to the end, it might be you know what are the diagnostics and devices to be able to create ways to interdict and prevent this.
All the science is great but maybe there need to be devices that are stuck in every location that we want to stick them in there and they do two things: one is they monitor and they sense. And certainly every sensor is a small computer. They sense the inaudible range and they end up alerting through a cloud network the security services, if there is an intrusion and insult that's that's being monitored and shows up on our grid. And the other is we actually interdict it. Now that's the operational thing that quite frankly wouldn't be hard to put together, and that's an operational deployment.
Before we get there I'm going to look at some other issues as well. All right. So the other part of this neuro-Moore's law is not only every device getting smaller and more powerful and cheaper to deploy but it has to do with the proliferation of those five key technologies I talked about. so it's the proliferation of nano, bio, IT, neuro. So you heard Dr. Giordano reference nanoparticulates and nanotechnology. Again the manipulation of matter at the atomic leve, l just let me remind you the era that we live in, right? Anybody out there manipulating matter at the atomic level at home? What, you could, you don't have to have a big lab, right? CRISPR is a technology for doing genetic engineering, you know what the skill set is? Operating a video game. You know, we're living in an era of accelerated proliferation of 30 or more technologies which we don't have find the prosecute today and the implications obviously for security and defense and intelligence are massive. As well as they are for healthcare, manufacturing, finance and the beat goes on. So that's the area that you're living in, accelerated exponential technologies, I named five, and we'll be drilling down more on neuro.
Now, there's also two parts of neurotechnology. I'm carving that out of neuroscience and saying okay, so here is something to pay attention to. And when it comes to neurotechnology for the applications that looks like (those) in Cuba and we think (those) in China against officials, American officials, it's likely there are two dimensions to neurotechnology. One is a soft dimension, which is dysfunctionality, cognitive impairment, the inability to be able to make good decisions. Even dizziness and health effects but certainly cognitive dysfunctionality as a delivery, as a weapon system. Think about that. And then there's there's the hard dimension, soft and hard, of neurotechnology which is rendering individuals not just dysfunctional but inoperable or even dead. Fatality. All right... So we haven't gotten to that. But the issue of non-lethality, of weaponized capabilities non-lethal weapons that are associated with neurotechnology, that is the era that we're in. So my operating assumptions to do this work are one: Americans were attacked, American officials were attacked, there was a signal sent by certain parties for a purpose, we'll get into that. And the conclusion is of course, why was that done, was to demonstrate a proof of concept, we'll talk about the implications of that and we'll get into who, potentially, the geopolitical actors might want to accomplish that. But you could follow that logic pattern forward to be able to run that out. This is an operational deployed capability, soft, non-lethal.
https://youtu.be/TzHj8KQfD7o?t=731 The possibilities in what we call hybrid conflicts are that there is now a new weapon, a neuroweapon technology that was now available. We have to accept that as the new reality. And we particularly have to accept it for authenticity purposes because it has already been deployed. And it was targeted and purposeful. I don't believe that it was an accident because of the cohort that was targeted. And now that we have two incidences that we can compare data on, we don't really need to see the data, we know that there's two populations that are similar, there are other friendlies that were targeted, so the assumption of accepting the deployment of a new weaponized capability, is: let's get over it, okay we got that. Now the issues are deterrence, prevention, diagnostics. That's my operating premise. So neuro is likely a game changer, maybe.
https://youtu.be/TzHj8KQfD7o?t=794 I want to now drill down, just, again, this is the larger context but there's a variety of things you don't think about that neurotechnology as an implication on, which I'm trying to point out is that it's a much larger phenomena in terms of impact domains, where it's in the wild. And many of the same agents I've seen and I mean neuroagents, these are in silico programmed bots, (which) are now programmed on the way we model neuronal interactions in dendrites. So again this is just a bigger phenomena of which this is one carve-out but it's not like there's not tremendous opportunities that are going on in other areas (and the implications). And we haven't even talked about, also, enhanced minds and and the performance enhancement from neuro and cogniceuticals goals which is a whole other dimension to this which are not getting into today. There's direct implications, the other side of what we're talking about.
Also, it's had a massive impact on healthcare, we don't have time to go after all this but you know, if you look at the far side on the right, it's neural enhancement as a deterrence for prevention for age-related diseases. Again, every dual use technology will have a dark side and and a light side. We're in that era and now, why? Because half of the population is at risk for Alzheimer's, the other half of the population will be caregivers or dealing with a phenomena, global phenomena which comes from longevity in a variety of other factors that we quite frankly we don't understand but has to do with the aging of the brain and may have to do with insults to our civilization that we're creating. Which is a whole other factor. But that's the era that we are in. There's a hundred companies working to defeat aging. Which have to do predominantly not so much with your bones, your organs or even disease, we're navigating that, have to do with cognitive dysfunctionality decline-associated. So we're we're in an era, you might say where cognitive fitness is a capability that we will all need to understand better and the neurotechnology therefore it's a deliverable in this era of cognitive fitness. One side is enhancement, longevity, health, the other side is weaponization. I want you to just put that out it's a context you understand, for those of you who are unfamiliar where it is.
https://youtu.be/TzHj8KQfD7o?t=959 Everything you ever hear about robotics artificial intelligence, all this is what? Converging with neurotechnology. Can't get there without that, we're building robot brains, what are they going to do, they're modeled after what? Nature, bio, nano, mimetics. Parallel phenomenon, right? Not many folks understand the convergence of these factors. Remember, five key technologies. All right so neuronal self-assembly, again we're in an era where you know, one of the factors of nanoscience... And I was the first private sector advisor to the interagency working group on nanotechnology. So what we did at NSF was, we created, helped create the world revolution in nanotechnology by first investing under President Clinton and then under President Bush. We basically funded the formation of an entire new domain, nanotechnology. But really it was to be able to say nanotechnology should be at the table with these other key technologies. Why am I talking about this? Because when you start to talk about neuronal self-assembly and nanotechnology, you're talking about the ability to be able to create an entire new marketplace and understanding of science and drugs and other things and the dark side of that, the dual side of that which is weaponized capability. So that was a reference by Dr. Giordano made earlier, (for) which there is a whole other conversation we could brief on which has to do with nano, bio, neuro.
https://youtu.be/TzHj8KQfD7o?t=1051 Neuroreprogramming is likely the driver or architect of and the defeat of age-related diseases. And remodulating skeletal and organ combinations and the ability to be able to revise analyze and rejuvenate even your brain. And again this is stuff that sounds science-fiction, it's really not and we're getting there a lot faster and it'll likely be delivered as a device.
https://youtu.be/TzHj8KQfD7o?t=1079 Okay, so I would hypothesize that neurotech is going to be a contributing factor in driving the next hybrid war which is already started. And this is an era of again soft non-lethal moving towards something else. Think about the implications of a neural technology capability that could render for a decision-making command structure dysfunctionality in terms of decision-making and just distort time. I want to distort time. I want people to lose track with time and I want to affect that part of the brain that leaders have to do that. How would that affect the battalion, how would that affect the series of negotiators for a treaty? How would that affect people? You might lose track of time. And have a stress factor. Could I echo-locate and deliver that signal? Could I gentlemen? Yes. Possibilities are there. So we think about hybrid conflict as irregular forces, diplomacy. cyberattacks, economic warfare, what if this is a new contributing dimension to that and we haven't thought about that, we're not there. And if anything, this is a wake-up call to what? That capability said. You got to think about it in terms of deterrence like that. You have to think about that differently, why? Because we live in an era where most of our major threats have been because of the lack of imagination that it could happen. Why? Because we have most folks fighting, who were leadership for the last war. That last war by the way was yesterday, not tomorrow. Thinking about the last conflict. So my suggestion is we need to think or rally about these, again, one of the other factors of Moore's law, is the is the accelerated velocity of innovation.
Well, you could just listen to this alright, you're going back and you're gonna brief the command that there's, listen, there's these pest control devices you know, we think that created this, you know, this attack you know, I mean, I really want to do that brief in front of you know, Joint Chiefs, don't you? To hear them, to hear the laugh. Yeah? And it's like hearing, you know, guys hijack planes.
https://youtu.be/TzHj8KQfD7o?t=1230 So I just want to point out, interestingly, this is an example of a massive DDOS attack at St. Louis. Over the past you know year, someone is testing a DDOS attack on the West Coast. This is what it looks like, alright, this is what it looks like. Imagine that as a neurotechnology tone and notice also that what a botnet is, the core of a botnet is self-propagating wood. It's like a virus propagating in real time. It's an activated silicon programmable neuronal agent. That's a lot of what it looks like because once it's set in motion what does it do? It's like Ebola for networks. I'm just trying to disrupt your thinking, think along the lines, of how these it's a different way of paradigm of looking at this stuff.
https://youtu.be/TzHj8KQfD7o?t=1288 So as I said earlier every technology has kind of this, you know, dual side. So fantastic futures are low-cost designer drugs, stuff that, you know, as we go after being able to do proteomic targeting for cancer cells and living cells as bio founders. We're getting all there at the same time, we've got hyper-violent protoviruses, genetically selective pathogens, Trojan horses. Where you - same thing with neural - just apply that, this is applied to bio, play at the neuro. We need to be forecasting and imagining these kinds of models and possibilities because somebody's already shot across our brow. You know this is a clinical trial in the wild and they've used the target to be American officials. Now we've got two instances, we don't know any other instances, other like this, based on... So you have to assume it's a purposeful targeted attack. Okay? We got the message!
[Note: Referring to important slide, Figure 1 below] https://youtu.be/TzHj8KQfD7o?t=1352 So let's talk about this it's very interesting. Let me start with the data set in the middle, which is what is apparently “legal”. That's what's legal, in terms of confidence. The notice, it's psychological effects, psyops stuff, it's basically dysfunctionality-rendering, lack of capacity, acoustic weaponry. Alright. This is about ten years old, this slide. So it's not like this stuff is new, it's maybe being deployed in a new way, okay.
Figure 1: Slide from Dr. Canton's presentation
I also want to point out the effects and the effectiveness. We have had a lot of data. You've heard from our eminent faculty of doctors that this is: (1) credible, (2) here's what it looks like and (3) here's the science. So I'm not going to go through all that but I also want to point out that this is a patent from 1999. I did a scan as part of research with my team looking at patents and you know when you look at patents it gives you a sense of intellectual property of what people were thinking about that they wanted to do. 1999 you've got an acoustic heterodyne US patent 5889870 (https://patents.google.com/patent/US5889870A/en) of March 30th and it gives you a sense of what are the possibilities to be able to, what the science may tell you. Great. So also, this are devices that are being carried around from various sources, this one is from Canada, backpack that's Moore's law, the operationalization of Moore's law, but these are also devices that have been used for crowd control, larger populations. But they're targeted uses that are portable.
[Crowd control slide] https://youtu.be/TzHj8KQfD7o?t=1475 These are examples of deployments, real-time deployments. Again, am I saying they're exact for we've seen in Cuba or in Asia? Similar. But these are for crowds. In the circle is the devices that are mounted, some of them I'm not going to get into exactly what the actual technology is but as you can see the people the hands over their ears, you know, it's how you get a fact. Okay so it's not like this has not been fielded as well, okay.
Figure 2: Slide from Dr. Canton's presentation - Crowd control weapons
I want to also say that you know the neurohacking which is maybe a term you haven't heard of, the ability to be able to create bots but also I mentioned that earlier blend it with AI... But sensors and networks we haven't talked about that. The ability to be able to deliver this. So these devices which we think that were used either externally to the habitats where the subjects were targeted or it may be internally but we haven't talked about whether there could be other kinds devices such as flyables, drones or they were tied to other sensors or sensors or hat. Where am I really going or this is that in an era where everything is hackable, everything is hackable, health devices, routers, I bet you you know a large portion of the folks listening to this in their home and we have some experts here can attest to this that most devices that are now networkable are what? Hackable. And neural hacking we're just you know as we develop devices to adjust or refresh memories, which we will have at the nanoscale, you don't even need them at the microscale, you're gonna end up, everything that can be made, can be hacked. And neurohacking is an area that we don't even have people really thinking about yet, because we don't have all the devices but that's where we're going, that's part of the story that we're learning today. Okay.
https://youtu.be/TzHj8KQfD7o?t=1618 Weaponized neuroagents, interestingly, this is kind of heading towards our bad guy actors here. You know, for all intents and purposes in the era of nano, neurobiology, synthetic biology, molecular delivery, the ability to deliver these days it doesn't have to be that sophisticated. We've had two events of use of neurotoxins that should show us. So one part of the continuum is kind of crude weapons and they're clearly weapons right, the Russian neuroagent used in in Europe against targets, that was purposeful. Then we've had another example of the agent used to inflict insult and mortality in Asia against North Korean X resident. So for all intents and purposes, that's the crude part of the neurosupply chain. This is a more sophisticated non-lethal part of the supply-chain, neuraweapon supply chain alright but I would forecast is going to be a lot more. We'll talk more about that doesn't not have to be as sophisticated and this.
https://youtu.be/TzHj8KQfD7o?t=1691 Again we don't kind of prosecute this but in the modeling of where it can be done... At the Potomac Institute for this conference on neurowar and the implications of neuro technology we modeled out a variety of things, of which we've done about since that time, about 2014. About half of these are now deliverable as capabilities.
So the other part of this, as we make a transition now from talking about really kind of an overview of technologies and drilling down on neurotechnology, I want to talk a little bit about the other complimentary story, the geopolitical implications and of course who might be potentially interested in doing this.
https://youtu.be/TzHj8KQfD7o?t=1739 So this is again a body of work that I had developed when I was advising SOCOM: Iran bad guy hunting targeting. And I came up with this concept of dark networks. Dark network is a criminal terrorist, sometimes sovereign, who worked together in a supply chain to be able to create and implement and plan and deliver. So in these global dark networks which is kind of what has evolved, there are a variety of actors, rogue states, radicals, non states, criminal who involved in a variety of parts of a supply chain that you need to be able to make stuff, deploy stuff and produce disruption and conflict. You have to have banking, you've got to have logistics, you've got to have things to trade that are non-monetary, you need to have crypto - where's our crypto friend, there he is, call out to the crypto world, crypto currencies - you've got to have the ability to be able to have other monetary forms to support your operation that are non-transferable, trend discoverable, you need to have a complete supply chain.
Think about it like, you know, Walmart has a supply chain, right? They grow stuff and make stuff all over the world and they figure out where to ship it to, to assemble for the best taxes and which monetary unit to use, where to deliver to, what markets or... It's a supply chain. So dark networks have supply chains. Criminals, terrorists and sovereigns, bad actors have supply chains. So if you're in the bad guy hunting business, you got to understand the supply chain. Follow the money, follow the logistics, follow the customers, follow the producers.
https://youtu.be/TzHj8KQfD7o?t=1852 So when we start to apply that thinking to who are potential bad actors that would do this and why, you have an interesting model. So I built the model around that, years before. But you also start to look at what does the literature indicate regarding who might be interested. The Russian view of modern warfare is based on the idea that the main battlespace is the mind. Well, interestingly, remember I said earlier about the supply chain around neurotechnology, you've got on one end, blunt tools, use neurotoxins to take out parties, you got subtler tools, which are information warfare and now we've got more aggressive stuff, penetration of elections, fake news, fake identities and all that. And then you've got these even subtler kind of non attributable phenomena, which is these incursions in Asia and Cuba. It's part of the same thing. You might add to that also you know Syria and other folks that are using neuro agents. So again, you want to start thinking about these as supply chains, ecosystems of involvement.
Bad Guy Hunting Threat Analysis
Figure 3 : Slide from Dr. Canton's presentation - Bad Guy Hunting Threat Analysis I
https://youtu.be/TzHj8KQfD7o?t=1926 So let's take a look at, this is the bad guy hunting threat analysis and I am working with a couple of other folks in this space, one is (...) about that guy hunting. But let me give you a kind of list and I'll prosecute a couple of them. So the threat analysis goes, it basically cuts around who, what, where, how and why. Not hard to figure out, that's what we're looking at. Identity analysis, what is this, is it an agent, is it a device, I think again I'm not gonna go back and do what our distinguished doctors had outlined for us because (...). I think it's important as a takeaways, this is not, as far as I'm concerned, you know an accident or some happenstance, this is a directed purposeful target at a population that are American officials and I understand there may be other officials from other friendly nations, but for all intents and purposes this is a capability analysis that's been deployed, targeted, chosen. So the second is, kind of benefits, wins and loses, who benefits from this. Who benefits. Well, the first order of benefits are the folks that are perpetrating this, what are they doing? Demonstrating capability said. Why would that be useful? Who would benefit from that? What's useful is to be able to determine what the impact is and did the impact confirm what our objectives of that was. I said earlier this is a clinical trial in the wild on humans. The second order of that is against whom. Well, the who is America's. That's very valuable to who? Well, that's a short list of people that would sponsor that and maybe they didn't sponsor it but maybe it's bad actors, rogues that are basically advertising. We'll get into that a little bit more. I talk totally about vendor supply chain so I don't want to go into that but I would say the vendor part of that is very interesting.
I bet you today, I can find similar pest control devices in Baghdad over the Internet. I ran an operation where I was putting together, I needed a drone delivery, I picked up the internet, found four or five places throughout Baghdad, Iraq, Afghanistan, Paris, Marseille to put together an order. Nobody ever asked me why I wanted to. Could I find pest control devices and a variety of other technology that are clearly available and I can ship them from FedEx, maybe even buy them on Amazon or Circuit City and have them delivered (not Circuit City anymore) Yeah. So vendor and supply chains very interesting.
Ideologic, for profit, research, likely all of them, probably the least is ideologic. So you know you think about things as ecosystems of interacting and related... folks don't be fooled by ideologies, 80% of the bad guys are doing it for some kind of profit, they are in the game. I mean the fuel that drives ISIS is the oil. It's a commercial enterprise the Taliban.
Figure 4 : Slide from Dr. Canton's presentation - Bad Guy Hunting Threat Analysis II
https://youtu.be/TzHj8KQfD7o?t=2132 Also number six is interesting geopolitical signaling and payback. What has occurred recently, what's the short list of trade sanctions that are currently been deployed? Against who? The short list? Look at the list. Is there a geopolitical payback of which this event might be related to? Or what are the implications of that? The short list for major countries. Not hard to figure out.
Rogue, sovereign, dark network. We spend a lot of time trying to figure out, is it this or is it that, maybe it's all of it. Maybe it's a carve out that doesn't know and they're playing. Also at the end of the day likely this event is a contractor looking for business, it wants to prove up a capability and you got to think, wait a minute, Cuba kind of get that a backorder, we don't really have a embassy per se you know. In China, given the treaties and associated with this and the target of the population, wait a minute. So that in some ways who does that eliminate? Probably eliminates China. And probably then you start to ask yourself who would benefit from trying to being embarrassed with this insult occurring where they're responsible based on the treaties against Americans. That's a shorter list. It could get more complicated because you've got what I call, we'll get to this, a fractured sovereign scenario. Okay I don't want to go into all this. It's like if you look at the incursion in India back in the day of Mumbai. That was an advertising for a capability that was deployed someplace else in the world. So you got to think geopolitical in terms of what are the largest cities, what those supply chains look like. And don't look at me over here, I'm going to try something over here but I'm really interested in showing this capability for something else. Think about it like the history of comparable events for analogous deployments, like cyber. Could neuro end up looking like cyber and the answer is yes it's a proven up model, in fact a product line extension from cyber would be neuro. Why not. Hey, we've done great with cyber and turns our profit center and now we've got a new capability, who wants to sign up? Prove up the capability. The commercialization of weaponized technology is a key driver. More so than you like.
Figure 5 : Slide from Dr. Canton's presentation - Possible scenarios
https://youtu.be/TzHj8KQfD7o?t=2323 Here are just the possible scenarios and then I will move forward.
(1) Fragmented sovereign
Fragmented sovereign is, most countries have a variety of warring factions that have different perspectives, ideologic, political, economic and for various reasons. These competing forces in regions and nations produce what we call fragmented sovereign. And a fragmented sovereign scenario says bad guys basically have implemented this that we're talking about, this new incursion, because they're trying to accomplish something else. You got to think three steps ahead. Well, they do this to be able to engage this, to get people busy over there but they're really interested in something over here. Fragmented sovereign.
(2) Terrorist clinical trial
Second is terrorist clinical trial, these are pretty self-explanatory.
(3) Rogue Actor Practice
https://youtu.be/TzHj8KQfD7o?t=2384 Likely I would bet on this as rogue actor practice. And that this is a messy clinical trial because they get to do what? They get to have the Americans who have the best research, to go ahead and do analyze it, bring in the best doctors and then do what? Open democracy, publish all the data, publish it all, do the hard work for us, thank you very much. Now we know and what's better than the Americans to be able to analyze this, because I can't find any Chinese reports. I have seen no Chinese data, very few Chinese reports, no pest control you know Chinese, denials.
(4) Asset for Hire Advertising
So this is something that understands. Now, I'll give you the profile right. This is a private sector bad actor who understands what? He understands social media and information warfare. Clearly he wants to advertise this capability, wants to embarrass the Chinese or at least put them in play and is attacking a select group of State Department officials that have functions. Two nations. Now who's on that list, that's shortlist. That's a short list. Do the math on that.
(4) Dark network show of force
And then a dark network show of force, criminal terrorist organization that again they'd only do that I think because of a commercial (...). Next slide.
So let me just say, willing to make a forecast and look forward. So you have to assume that we're at the beginning of neurotechnology being now incorporated into this kind of hybrid conflict era (number one). Two, you should recognize and I would suggest that we are looking potentially at additional instances. Why? Because this has been so effective. Americans played their part, host country played their part. A lot of good data, we're getting more data, are we getting more data? That's great. Cuba, China we got more data. What's the next target? We don't know. It's likely, it's not going away because it's been an effective trial but it now is revealing as a deployment. And of course the insult is, we're not talking about rocket science, we're not deploying you know some laser quantum fusion cannon, you know there's not like super sophisticated technology, which makes it even more interesting. So you're likely looking at as I said earlier the two parts of neuro technology, the soft part for all intents and purposes is hey, you know, you're talking about cognitive dysfunction, you'd be able to deliver, a deliverable as cognitive dysfunction to impact what? Decision-making, operations, negotiation, communications, that's a big deal. The hard part is - unless interested in - I don't think the design of this weapon is to kill or maim, I think it's a take parties out. And likely these State officials are not folks that are going to be able to go back in the game. So you got to think about that as a kind of a long-term impact and risk factor of which there could be additional locations.
Is it possible we could be looking at super drones that could deliver this in terms of capability said? Well we haven't looked at it but yeah that's a deliverable. It's episodic, it's acute, it's here, it's gone, you can deliver from various levels. There are questions about the ability to be able to deliver echolocation and these other targeted things from 35,000 feet or 5,000 feet and we don't know the answer to that. But there are devices that give us capabilities and again shrinking stuff down.
https://youtu.be/TzHj8KQfD7o?t=2631 So in summary let me just say to: (1) neurotechnology is here, it's not going really, it will likely shape the competitive advantage of nations, organizations and individuals and that's for both good, bad and ugly. So let's get on with it. Second is that the attacks in China, Cuba appear to be purposeful and directed at a population that by the way could be expanded. And three, the target, US officials is revealing in itself. And there have been no other instances similar to this, similar pathology, similar any place else that we were aware, so I think somebody is sending a clear geopolitical message. It is a bad actor whether they're in alignment with other sovereigns and that. So who would gain from this. The sovereigns again is a short list but it's clearly signaling a geopolitical signal. There is a communication going on. A new neurokinetic weapon would be disruptive in an era of hybrid conflict and we have to assume that we are in a new era. And that new era purports that we have to have a way to deter, prevent and detect. Thank you.

Transcript: "I d’first like to thank the organizers and everyone here for this kind invitation to speak, so I can share some of the ideas that we have been pursuing, looking at some of the mechanistic basis for how acoustic and or radio frequency exposures might affect the inner ear and the brain.
The work that I'm speaking about is a follow-up. We've known about energy exposures for some time. Noise exposure, for example, is one issue and this has been a major issue for hearing loss with noise exposure in military environments. And in fact, the work I'll be speaking about is supported initially by the Office of Naval Research. It's noise-induced hearing loss portfolio and the program officer Kurt Yankaskas unfortunately could not be with us today. But Kurt deserves a real shoutout for being right at the tip of the spear on this and really he's been along with us working from the very earliest time we called him up when we saw the very earliest exposures in Cuba and has been a partner with us fully. And I just wanted to acknowledge this at this point. His program, and you'll see some of that, you see some of the spirit of this through the talks that we've had so far, spans from looking at:
What are the noise sources (it is a systems approach)
What are factors that lead to human susceptibility to it
Prevention and treatment, and
How do we design personal protective equipment.
And you'll see, these are the first attempts to bring this sort of approach into the code 34 program at ONR.
Now, the scenario behind all this that we're discussing is the type of exposures that we've heard about that we're seeing in Cuba. Next slide please. And we've already heard the other speakers, Dr. Hoffer, Dr. Giordano refer to the fact there could be a number of potential energy sources. We know something happened to people, but we don't know what did it. So what I'm going to do today is go through some of these possibilities and looking at it from the perspective of sources.
One of the sources are hypersonic sound including LRAD type devices or that type of technology. Pulsed radiofrequency; there could be pulsed laser source or there could also be ultrasound such as the new photoacoustic devices (...) that are very small but actually very powerful and could be used in certain frameworks for it.
And the focus of the ONR work actually, the title of it, is “waveguide resonance and cavitation, properties of intracranial contents”. So that gives you sort of a picture of where I'm coming from. The question is if people are being exposed to different kinds of directed energy, what's receiving it, what's amplifying it, what are the vulnerabilities inside the head and other parts of the body. We don't know a lot about that now. But (...) if we're taking a look at these kinds of mechanisms, at wave transmission, resonance and cavitation properties, this is possibly a way that you could get additive effects for many of these multiple modalities of energy delivery simultaneously to the individuals.
Now so what I'm going to do is sort of go through three parts.
I'm gonna go through three general parts here and give an overview of each of them. The first is to take a look at research done, published research from the 1960s through the 1990s that deal a little bit with ultrasound and radiofrequency effects on inner ear and on brain. And we'll just consider this. There's a lot of work that's been done actually. The work that's done, I'm sampling from the papers, but this gives us a proof of concept for how to proceed. We don't have to start from square one. There was good work that was done before, funded by, among other sources, DoD.
And the point here that we've made, I want to stress that here (...) we're talking about hearing and hearing injuries or sound injuries. Consider the saccule and utricle to be part of it. The “Vestibular Evoked Myogenic Response Potential” that Dr. Hoffler talked about is recorded by playing a loud sound in the ear. The saccule and utricle sense linear accelerations, will also be sensitive (...). I will then go and discuss a little bit, we'll go through some, just to show you some of the COTS devices that are currently available for ultrasound and for radiofrequency application. They're used for sound delivery by modulating the ultrasound. But they're also used for pest control and I'll show you their wide availability, technologies out there and (that) in fact could be re-engineered and in a fairly small form-factor to be just placed in somebody's room. Finally, what I'll go through is illustrate some follow up on work that we've done with data that we hadn't previously discussed from the individuals who were affected from Havana looking at an eye movement-based test that can distinguish them with 90% overall accuracy from normal people and people with an acute mild traumatic brain injury.
Intracranial Wave Guide, Resonance and Cavitation
J. Vipperman, G. Klinzing, B. Saltsman, S. Mang
So this is the first portion I'll speak about. Some of the intracranial waveguide resonance and cavitation literature. And my colleagues, J. Vipperman is a Professor of mechanical engineering at University of Pittsburgh. G. Klinzing is Professor Emeritus of chemical engineering with expertise in cavitation related to pneumatic conveyance and two graduate students working with us, B. Saltsman, S. Mang. Next slide please.
So if we take a look at biological effects of directed energy, we all know that directed energy can affect, we can have various kinds of neurosensory symptoms and signs. And we have examples, if you take a look just in the occupational safety literature, the literature around introducing ultrasound into different industrial processes and also ultrasonic imaging, there's a large literature talking about safety, occupational environmental exposures and also untoward symptoms that we have come up, balance, hearing loss and features like that.
So one of the things that we are doing right now is looking to characterize the waveguide resonance and cavitation features of cranial contents. Dr. Giordano kindly reviewed all that, went over the basis for all this material. Blood vessels as he showed you are surrounded, major blood vessels are surrounded by interstitial fluid, brain fluid which is confluent with fluid in the subarachnoid space and look like coaxial waveguides in the Virchow-Robin spaces. Next feature, we have the ventricles, this external system which he mentioned again. Fluid-filled, possibly resonant chambers. We have the inner ear, we also have P air spaces, we have our sinuses, we have our middle ear cavity, all of which can act as amplifiers and have effect through cavitation as well as through different acoustic resonances of the structures.
[Simulation of presentation of sound waves to the human head]
[7min36s] Now this is a simulation (we'll play it in a moment) presenting a multiple sine wave. So sine waves being presented to the (head). This is a finite element model of the human head. The publication reference is here https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0113264. Dr. Vipperman and I did this. It contains hard and soft tissues. Brain is modeled with different white matter and gray matter constituents to it. Blood vessels are not included, the meninges are included. So I want to say right off, models as we discussed before are a nice way to think, but the joke is you can sometimes tell a person how a spherical horse runs with a model, depending on if you put legs on the model. So this doesn't have all the legs but I think this can show us some principles. Would you play the model, would you play the simulation please? (Play link: https://youtu.be/j1kKy82W0GE?t=500) So three sine waves are being played to this from externally and they are at 10, 10.166 and at 10.322 KHz. So this is as if you present a signal. Let's play it again please.
So what you'll see is a beginning in the ear and then you notice this is resonance in the subarachnoid space moving along that and centering right over here, over the temporal region. We saw the middle cerebral artery. It is a major artery with everything conveying along that area. (...) Next slide please.
Now, with this one, it's the same model but instead of having three different sines, we simply put in pseudo-random noise in the ultrasound level above 10 kilohertz. Next slide. So you see the same pattern when we're working with incident energy in that area. It is producing resonances, resonances over certain areas beginning in the ear and moving out into the subarachnoid space in a model, okay... Just let's store that away and remember this area as we look forward through some of the literature.
Acoustic stimuli: Georg von Békésy and Cochlear Transduction
[9min44] Now, the classic idea of acoustic stimuli impinging on us. We think about the ear and the cochlea is a transducer. The classic work on this, the Nobel work of von Békésy on cochlear transmission, in fact he was funded for a while for some of this work by Office of Naval Research historically back in the early 1960s. The mechanical resonance of the basilar membrane is one of the features as Dr. Giordano mentioned. The peak resonance varies from high frequencies at the cochlear base to low frequencies at the cochlear apex. So if I have high frequency ultrasound input in, where is it affecting you? Right down at the base. What's right next to the base? The otolith organs, your organs of balance and the activation of the sensory cells with relay through. Next slide please. I can show you this, okay. (...) Here is a cross-section through a human ear. (Figure 5). You can see the basal, middle and apical turns of the cochlea. Here is the hearing apparatus and if you unwrap it like this from the base to the apex, this just shows that when sound is incident at a certain level, it sets up a standing wave at a certain frequency. Based on the resonance of this membrane, this resonance it's like a resonating beam like a xylophone, it's going to resonate. And at the point where it's resonating these hair cells which are on the surface of the cochlea have their tips deformed and they transduce that sound. That's how the hearing system normally works. Now what you'll notice is off on the lateral edge here (I'll walk over here where I can point to it) you'll see there's a structure called the Stria Vascularis. We'll get to that in just a moment. Next slide please.
Figure 5: Slide by Dr. Balaban entitled "Classical Cochlear Mechanics". (Slide 12 in pdf link)
So here this just shows you, this just shows us that we come to the base of the cochlea, the hook portion of the cochlea which is excited by extremely high frequency sound. Sits in very close proximity to the organs of balance, the saccule and the utricle.
Figure 6: Slide by Dr. Balaban entitled "Vestibule and Hook Portion" (Slide 11 in pdf link)
So take-home message: they are in vulnerable spot guys, they're sitting right there.
Figure 7: Dr. Balaban mentions take-home message.
NOTE by information-book.com
Please refer to section: "Ear as a frequency analyser" http://www.information-book.com/neurosciences/ear-as-frequency-analyser-otacoustic-emissions/ for more information. The following figure is provided as reference
Figure 8: Please refer to section "Ear as a frequency analyser" http://www.information-book.com/neurosciences/ear-as-frequency-analyser-otacoustic-emissions/
Now another very interesting area that's come on, we started thinking about sound exposure. I realized that there was an area in the literature, I ‘ll go through right now. The Stria Vascularis is one of the regions that is important for recycling the endolymph and perilymph. Now the endolymph in the ear has a very high potassium content and it's important that it be 80 millivolts difference with respect to the perilymph in CSF. And this is a highly vascular structure that's really important for maintaining that ionic difference because potassium ions would drive the hearing process. You'll lose that potential difference, you'll lose that ionic differential, you're going to impair hearing and you're going to impair balance. But the Stria Vascularis has also in it a very intricate network. So here's the basilar membrane and you can see the Stria Vascularis arteries enter from the top. It percolates through this system and comes out venules at the bottom. And a methacrylate cast of it is shown on the other side. So what it actually looks like if you think about two pieces of chain-link fence, a two layer chain-link fence of a blood vessels network, vessel coming in from the top, vessels exiting from the bottom and the flow in these vessels (we know their dimensions) is non-pulsatile. What we have set up here is something that could be a phased array cavitation amplifier okay. I'll leave it at that point, that's one of the things that we're looking at right now. This is a structure inside the ear and in fact it's tightly packed with blood vessels which can act as cavitation sites when exposed to sound. Next slide please.
[13min54] And in fact it differs down in the portion of the base of the cochlea. There's a focus in kind at least in rodents where it's been looked at, it looks almost like a parabolic reflector pointing in down at that area suggesting there might be differential amplification. And so what this may do actually, we'd suggest is maybe a cavitation type of an amplifier. Now how might this work. This is a picture from Apfel’s classic work on acoustic cavitation from the book on ultrasonics in 1981 and this is just showing a frequency spectrum of output when you subject water to a 10 kilohertz acoustic stimulus. And you'll notice what you get out is a very characteristic spectrum, at relatively low intensities, you basically get a whole bunch of harmonics kicking right out. Looks like a comb coming out. You increase it a little bit you start to get half harmonics. Increase it a bit more that's what you get out. What you're effectively doing is taking one frequency in and you're amplifying over a broad range. By the way this gives us an acoustic signature to look for, for cavitation now in animal exploration using small hydrophones.
And just to point out okay at the time when we're worried about ultrasound safety for imaging, a lot of work was done looking at blood and they were going up in the megahertz range because they were interested in imaging. You'll work down in this range, needless to say we have good enough data to go on to start doing modeling and validation studies from the previous literature.
So one of the suggestions we have here is incident sound waves. We want to take a look and see how does incident sound (...) on the ear - might this be a mechanism in real hearing also. So there is literature in fact which gives us the basis for looking at it. You can see considerable pressure difference, (there) is actually a much higher pressure difference recorded inside the cochlea, pretty high sound pressure even to regular sound coming in through the normal transduction mechanisms. And what we can do here is, we have the potential to measure directly in these cases. Next slide please. And this just shows you some intra-cochlear recordings that were done of pressure waves. And just to show you this can be done, this has been done and you produce, you see an amplification in the sound level inside the cochlea over what we have coming in incident in the air and theoretical calculations suggest that it exceeds by several orders of magnitude cavitation thresholds for the liquids we'll talk about.
Now, when I was thinking about this, one of the good things or bad things about having a memory and being a professor and having read literature for years, (...) I remembered this paper from Fred Natales lab when he was at University of Michigan years ago, some of Quark’s work and this was published in 1991. And what they did was they put a fluorescent tracer in the blood and they are visualizing with a camera the lateral wall. They're looking at the vessels in the Stria Vascularis. So imagine you cut away the side of the cochlea and you're looking in there and watching the Stria Vascularis as you play loud sound. And what they observed was under control conditions the blood is flowing slowly through. You can see the red blood cells moving through. When they played about 110 decibels sound, you know the flow, this blood vessel didn't collapse, it just looks like a void space. Remember oxygen and nitrogen are dissolved in the blood. One of the possibilities is we actually have a compression-decompression. Does what? We know about this from underwater environments and aviation environments, right? You can get to compression sickness, you can get local bubbles or emboly of different kinds of different gases. They couldn't say what it was but again it recovered when they turned this off. Suggesting that there are sound induced events affecting the blood flow and possibly affecting the partitioning of gases in the blood.
So we come up with an integrated view that cavitation of water and blood can appear, they can occur within the audible and outside the audible range of frequencies of acoustic stimulation of the cochlea. Pressures come up into that area and dissolve gas, may form bubbles. Hypothesis okay. A possible mechanism highly plausible based on existing data.
https://youtu.be/j1kKy82W0GE?t=1130 Now what I'd like to do is shift to the Frey effect as it is called. In fact I spoke with Alan Frey a couple of weeks ago, he's working as a consultant in the Washington area still and remembers this well. Very useful, we'll be back in contact with him. But he was telling me how he went to a meeting and someone working with radars said: “I can hear the radar pulses”. He was skeptical, so he went up to a radar facility with the guy, they played it at him and yes indeed he could hear it. And so this is the first paper describing it from Aerospace Medicine in December 1961. Next slide please. And what they did, looking at this in more detail, they went up and basically with all the different kinds of radar emitters they could get their hands on easily, they played different pulses at each other and they found that they were indeed audible and that they could block it by putting a piece of screen over this part of their head. And I asked him how do you figure that out? He said, “oh I just took a piece of copper screening up with me that I had grounded I was moving it around”. And he said “you put it there it would block it”. Looks like a familiar spot doesn't it. Coincidence maybe.
And there's a small but very robust literature showing that human perception will vary depending upon the integrated power delivered, looking at parameters that could underlie this perception. And in fact this was pursued, some work supported by Department Defense Office of Naval Research looking at impulse exposures to microwave energy. In this case they put a little electrode on the round window membrane so you could record cochlear potential changes and played microwave pulses, roughly 900 Megahertz range pulses to guinea pigs and they recorded an ultrasonic emission. Meaning that the ear was emitting at that level and was excited at that level and in fact ringing at that level. Next slide please. And because this was fundamental work, I'll show you just to get a feeling for the original data. This is recording when there's a click either initially positive or initially negative, this is what you'll call the microphonic potential that comes out from that. Here is when it was played on the same time base, when they played a single radar click and this is magnified about a hundredfold in terms of the time base. And you can see how it is ringing. What they reported show you the traces that when they went with pulses ranging (...) you can see the different total energy delivery per kilogram that came out of this. But if you take a look at the range in times one microsecond to 10 microseconds you got a resonance inside of the ear. Ok? What is it? Next slide please.
They really don't know but there was some work out of the former Soviet Union where they did something I would be reluctant to do nowadays, they took a big old horn antenna and stuck it right up on the side of the head of people and they asked the question: at what frequency of pulse repetition do people hear radars. They did an audiogram for radar pulses and they found in the 10 to 15 kilohertz pulse repetition range, a maximum sensitivity of people for it.
Now other work I'm just I'm breezing, these are not all the papers, I'm picking just a few illustrative cases. There was work done recording from neurons in both the auditory nerve and here from the cochlear nucleus, this time in the cat, and they basically showed that cells with acoustic responsiveness, typical acoustic responses also could respond to radio frequency pulses. So the ability of radio frequency to affect the nervous system through some mechanisms is real. Next slide please.
And in fact here's one of my favorites even though this was published in 1988. They took a cat and put a series of hydrophones into the cerebrospinal fluid and played radar pulses from the back of the head of the animal. And this is a power spectrum coming out. You notice how it looks like a comb? They had no idea what mechanism was there, they said it's clearly propagating but it sure looks like it could be a cavitation type of phenomenon.
So we see, they were positive that the thermoelastic response was responsible for this audibility and we have several mechanisms that are possible for this, including effects on the saccule and utricle and perhaps effects through intracranial blood vessels. So all of the mechanisms that Dr. Giordano spoke about are actually supported by a fairly robust older literature and sometimes we have to just sit back and read the older literature and remember that we're standing on the backs and working on the backs of those people who did some really fine work, dedicated people and many of them DOD-related researcher at that time.
So this just reminds us of the location of the otolith organs. You see it is hanging loose in close proximity to the base of the cochlea where the frequencies we are talking about are expected to create maximum resonance.
https://youtu.be/j1kKy82W0GE?t=1468 I'd like to point out there's some very small COTS devices that with modification could deliver this if planted in someone's room. Many of these in principle, can be put in something like a heating duct, an HVAC duct, could even sit in a thermostat.(...) Here's one device that I listed, I urge you to look up this at https://myskunkworks.net/. They tell you that they have a power amplifier and here it can be used as a phaser pain field generator, if you use it with our sweep frequency I see or for experimenting with an LRAD sonic weapon. There it is, sitting right out there on the internet available for anyone to buy with PayPal. Next slide please.
And this shows all of their ultrasound products, that they sell. Experiment with your own sonic weapon guys, okay? This is out of the bag, it's Pandora's Box open. This is from a major retailer and this shows you what they sell for pest control, the latest in pesticide for your pest control! Ultrasound, ultrasound plus electromagnetic pulse. Ultrasound, all of these advanced pest repellents. Guess what? They're being produced at a lower range than we need to see the effects we want but they're being stuck by people in their own houses. Suppose someone decides to soup it up and give you the next super duper one. Are we looking at a public health risk? Maybe.
Here's one of my favorites okay. I woke up one morning to news radio and they had this “make your house pest free”. They were describing this, I looked it up. They're pumping electromagnetic pulses through the wiring of your house, to eliminate pests, okay? Guess what. Anybody can, okay? The technology is there, it's in a lower level, you think that an adversary couldn't very easily design something a little higher power, okay? It's there, it's out of the box.
Now, one of the things that we've been experimenting with is a version of this device called “sound waves”. This is called a parametric speaker. You see a whole series little elements there. Each one of those are piezo-electric emitters and this is a 40 kilohertz carrier. And the way it works is you can project a beam, we could project easily all across this room, it is about three feet in diameter and if you amplitude modulate the 40 kilohertz with whatever you want, with speech or something like that using a carrier frequency, you will hear the sound on beams (being used) in museums and other places. You walk off being misguided. Sounds a lot like something we heard about that was described to Dr. Hoffer by some exposed individuals. And they sell a variety of devices. Next slide.
And this is the one of their devices that we've been working with a little bit. It actually uses a series of commercially available ultrasonic transducers. We can pull out the properties of each of them, easily if you take off their amplifier, usually you can crank out 140 DB out of this device at a meter and what I'd like to do here, just before we play it, here is that board and I'm going to show you one of the first time we saw this in the lab. The graduate students are going to move the board over a cup of water and watch the cavitation on the cup of water. Please play it. We're not getting the sound but there see the water? That's a standoff across the interface and it looks like we're working with it, we have high-speed cameras on the side and such looking at this now and it looks as if the surface tension of the water is creating nucleation sites for cavitation. So yes we can get with even commercially available devices without scaling this up or anything else, just putting a little more powerful amplification on, we can get cavitation across an air gap.
Operational Scenario for Technology
So now let's shift a little bit to take a look at what might be going on in Cuba and what I'd like to do is present some evidence of a technology that could be deployed far forward for detecting something like this, caveat okay. We only have those 25 people exposed as our pool to look at. So we're basing this on limited data. But I'd like to show you what we do have right now, next slide please. And this again is part of the ONR, Noise Induced Hearing Loss Program portfolio. So we talked about these potential types of exposure, next slide please. And we saw, reviewing what Dr. Hoffer presented, a high prevalence of what looked like otolith (saccule and utricle) related effects in these individuals. It was more homogeneous than you see in TBI populations and a much lower prevalence of headaches. So maybe it's like a TBI, maybe it isn't. And the cognitive symptoms were more pervasive and we saw some other elevated cognitive type of signs like an abnormal antisaccade test. And here’s a contest, you're asked to look, you have a spot come on over here, you have to look in the opposite direction at the same spot. And when we're intact we can do that, when you're as I put it, dings and not quite right in QR you have trouble doing the task. And sort of my definition of traumatic brain injury has been all along this. I don't mean to upset someone or mean to be provocative when I say (this). You have an event that they got dinged and they're not quite right, they meet the NQR criterion and (what) we try to do is quantify and specify what NQR means so we can treat them, diagnose, treat, document and take care of these individuals.
And this is just a publication we've been hearing illusions that otolith dysfunction or ear dysfunction can affect cognitive functions. This was done with a colleague, Ashley Wacom who's currently the chairman of Rutgers University and we found that we could document it in the wide range analysis of learning and memory type of tests that there were deficits pre-surgery in people with otocapsule deficits and when they were fixed and they were asymptomatic they improved their performance on learning and memory tasks. So this is one of the few studies that have shown, objectively, that kind of find.
So I also want to warn us, warn everybody, let you know we're not naive enough to think that if people think they heard something, there really was a sound there. Okay? We could by activating the area of the nervous system by something other than sound, like RF you could hear it, so we have to be very cautious and interpreting symptomatic reports especially after people have heard from other people what they thought they were exposed to.
[Vergence - Eye tests of Cuba victims]
So what I'm going to look at here now is some aspects of vergence and these are convergent eye movements which distinguish Havana syndrome from mild TBI. Convergent eye movements: if you follow your finger going toward your nose, your eyes will converge, your pupils constrict. And this is work done with Dr. Hoffer and Dr. Levine at University of Miami. And this is done with data that were gathered but these were gathered, these are things that Dr. Hoffler recorded with the eye device, but they're not medical tests, so we analyzed them post-hoc looking back at it. The device we use is right here, it's an neurokinetics eye portable assessment system. That's a virtual reality display. Inside it you can analyze each eye’s movement independently to better than 0.1 degree accuracy. It's fully calibrated and it allows us to control stimuli for the people to look at. And for studying convergence eye movements we can have spots moving and the disparity - watch them so you don't see double. We have no change in overall illumination, so we can study the convergence movement and movements of the pupil and eye without any interference of changing ambient light levels which will affect the pupil. So we can watch the eye movements, we image the eye under infrared diode illumination and we can track the eyes with great accuracy as well as measure the size of the pupil, the area of the pupil. So as I mentioned before, the convergent side movements we're all familiar with, as you move your finger toward your nose, your eyes will converge so you don't see double and your pupil constricts to increase the depth of focus. When you move away you get the opposite effect. The eyes diverge and the pupil will dilate.
And so we took a look here at 51 normal control subjects, 18 subjects with mild TBI taken from the regular emergency rooms at University of Miami, Naval Medical Center San Diego, Madigan Army Medical Center. So three different labs were making these measurements and the 19 subjects was completed data from the Havana affected population. And so two tasks were done. One I call the binocular disparity, sometimes fusion task. So you're looking at the display and at a certain point they move away from each other by a small distance about one and a half degrees and so you don't see double, you naturally fuse the two, we've all had that experience we do that all the time when they move in the other direction toward the nose. Second one we call a disparity pursuit task. They start like this and here they move, they diverge and converge but very slowly and we naturally follow them and during both tasks you have the illusion that it's moving toward you and away from you. They're making the movement like that and we simply record the eye and pupil movements during those tasks.
This shows you, from two different control subjects, one shown in green and the other shown in black, the eye movements and you see people follow that, the spot shifting quite well. And then these are the pupil movements going on at the same time recorded simultaneously. And this shows you for the pursuit the same two subjects. So you see if we follow it quite nicely and quite naturally and you'll notice the pupil is dilating when the eyes diverge and constricting when the eyes converge. And it's a very regular process that one can analyze with simple engineering models. Next slide please.
And in fact, this, I don't mean everybody to read. Basically from work done by Larry Stark and others in the 1980s, very fine work on this, we can model, make an engineering model and estimate parameters that describe these responses quite well. And this just shows you the model fit for a control subject for the eye movement. That's the gray line and just modeling the pupil based on the eye movements alone as the gray model on the pupil, does pretty well. The the fits are pretty reasonable. And I by the way I found out when they put the models up I thought oh I can do better than that and I probably went through every experiment that they did and showing why you couldn't - right afterwards. And then this shows you from a subject from Havana the same kind of data and one thing you'll notice foreshadowing it, you notice how much larger the pupil response is. Pupil responses really are larger. Next slide please.
So this summarizes data from the step binocular fusion test. And what I've plotted here is what's the amplitude of the eye movement converging or diverging from the model and you can see that there's no difference between the Havana affected people. But the people with mild TBI as we've seen before have a significantly lower magnitude of those movements. And in fact the fit, the coefficient of determination, the r-squared values are quite high for the model fits, so there's quite high fidelity, but the people with mild TBI don't follow it so well. So their magnitude is lower for the movement and less accurate. If we take a look at the pupil constriction, how much the pupil constricts per degree of convergence eye movement though, you'll notice there's no difference in behavior between the control and the acute TBI, but take a look, it's a more deterministic fit interestingly enough so maybe they don't have the other emotional effects on the pupil but the magnitude is much greater. And that's significantly different. And we see a very similar picture for the pursuit tasks except we see there that the amplitude of the eye movements is reduced for both the control, for both TBI and the Havana exposed individuals. But when we come down and take a look, the fidelity of fit is different and the pupil constriction is much more active, it’s hyperactive programmed at the same time in these individuals exposed in Havana and the same feature for the fits. So we take all these data, next slide please and if we do a discriminant analysis with it, very simple, I've got three different groups. How well can I pick out, based on these tests results, based on these test results these different groups. And you can see we get 92% correct classification. We take the one out cross validation, we get close to 90%. These people you get no cross classification errors between the Havana people and the mild TBI population. This is a fieldable technology (test).
So we think we have shown here, is first of all we can distinguish objectively by performance in these kinds of tasks, these binocular disparity vergence tasks. They show an abnormal convergence and (...) response behavior is distinct from what we see in (...) variety concussive injuries coming into a an emergency room. So what we suggest is, right now the current technology is something that could be taken out at least to a far forward medical station and deployed to see as a first read whether people had some kind of exposure. This technology itself, next slide please, can be miniaturized, okay. The form factors are not great now but within less than a year you could probably have something that could be installed on any battle helmet, on any helmet, any kind of headgear you want, instead of having the personal computer you simply put a processor right on the back of a custom-built camera, you can increase the sampling speed and get even more precision for picking up other kinds of eye movement deficits. This is ready for (...) at this particular point and pushing forward with these features and this is being supported, some of this, but at a slower development rate now by the ONR noise induced hearing loss program.
Finally, looking at this, I just want to say this technology and our ability to read the covariation between pupil and eye movements is potentially useful in many environments, OBOG type of problems that we see can probably be detected because oxygenation state changes the pupil responses. You can look at undersea hypoxia, hypercarbia in these areas and also what's the person looking at, how are they reacting to it. We could use this in a variety of different kinds of cognitive interfaces whether we're dealing with virtual reality or augmented reality kinds of platforms. So this is where we are at this point in time and pushing forward with it, we don't know what the exposure was, we're working along on that side, but at least it's interesting to see we can distinguish between them which is very important, which I think this is going to end up being very important operationally. We want to be able to pick out people objectively, take a look at it and so we don't just have these 25 people running down along the line, that we can study. Thank you very much for your attention and we'll get to questions later I guess."
“Embassy Encephalopathy”: Induced Hearing Loss, Cognitive Dysfunction and Neuropathological Changes - Possible Causes, Mechanisms, and Effects
James Giordano PhD
Departments of Neurology and Biochemistry, Georgetown University Medical Center, Washington, DC, USA
Transcript: "First and foremost I want to thank Lieutenant Colonel Snow for inviting us, certainly the rest of my esteemed colleagues, Drs. Hoffler, Balaban, Canton. Thanks very much to SOFWERX for having us down. Will be back here again in January to spend some time with you. My training, I'm a neuropathologist, I've been doing neuroscience for about 38 years. Very often my colleagues like to call me and jokingly we addressed us this morning, a disruptive neuroscientist because I work in the area primarily of the way neuroscience can be utilized for a variety of different purposes not all of the medical. And certainly on the medical side you can do two things. You can help or you can harm. You can withdraw certain types of care and that can be harmful or the very same things that work on a biological and physiological system through a variety of different anatomical sites can be inductive of things that are at least burdensome, if not threatening and harmful, I d’say probably what we've got here. So as you heard from Dr. Hoffler, he got a call early in 2017 that said “this is Department of State, we've got a problem”. In the middle of 2017, I got a call from Department of State saying “Dr. Giordano we've got a question”. “And the question is what do you think we're doing here, what do you think we've got here, we've got this set of findings and apparently this is going to be some type of problematic issue.”
My work is fairly well known for the term "neural weaponology." Back into 2006 and 2007 we developed a paradigm by which neuroscience could be weaponized and we assessed that on the world stage. In 2008, the National Academies National Research Council came back and said: “You know brain science really is not ready for primetime”. That was a misnomer. Our work in 2009-10 and the work of the Nuffield Council in 2013 demonstrated that not only was brain science viable and a value to be weaponized but in many cases it was already being weaponized based upon older technology that was now taking updates and being put increasingly into a variety of circumstances that would yield individuals to be in harm's way. We're beginning to see a little bit more of this and perhaps this is what we're seeing here. I want to start out with that premise because I'm not gonna point any fingers. I'm not going to make any accusations. However, what I want to do is to work with two things: the explicit findings and the implications those findings give rise to. Particularly in light of the fact that by 2014 the National Academies and National Research Council reconvened and demonstrated that not only were the brain sciences viable but they were in fact of high value and were in use globally as neural weapons.
Characteristically, we take a look at neuralweapons as what we think of is drugs, bugs, toxins and devices. Not all of these things will work directly in the brain, very often they will work on the peripheral nervous system or on the neurosensory organs to then have a feedback effect that are going to disrupt the process of cognition, emotion and behavior. What I want you to remember is that these are not weapons of mass destruction, these are weapons of mass disruption. Where the disruption can be on the level of the individual and then creating a ripple effect not only on that individual and their cohorts but on larger scales socio-economic scales. Geopolitical scales, military scales, keeping that in mind it's very very important to determine a pattern of use with the implication being that something's going on here and this was probably, very probably not an incidental event. Now, could it have been? Yes absolutely. What is the likelihood of that? Think about it. So if we're talking about things that go bump in your brain, there's a lot of different ways to get into your brain.
The primary findings as you heard from Dr. Hoffler were primarily autological findings and vestibular findings, things that happen in the ear and there are two terms I think that become important for you to understand. The first is the idea of otopathology which is there's something wrong there and the second is that this may be adduced to some toxic event. The initial thought was perhaps these individuals were exposed to some compound either an environmental compound or an intentional compound that then caused some type of pharmacological or chemical damage to the organs of the inner ear, whether that organ was the hearing organ, the cochlea or the organs of balance and orientation which are the semicircular canals, the saccule and the ampule. There are a number of different drugs that could do this. So we know that there are certain things that were called damage to the ear, structural damage to the ear, a blow, a pressure wave. There are certain drugs that can create a toxic effect in the ear or components of the ear and what these will then do is they'll affect a variety of the components inclusive of the nerve that emanates from the ear and goes into the spiral ganglion and then up into the brain.
So the idea of an ear brain connection is not far into this type of otopathology and ototoxicity. What are the various signs and symptoms: hearing loss, tinnitus, vertigo, disequilibrium, nausea, visual features, such as nystagmus and oscillopsia which you heard earlier. And then certainly a whole different types of headache and or disruption of cranial functions. There was not only headache but facial pain, unusual sensations and then a loss of attentiveness and cognitive functions that can be accompanying this. Next slide please. What type of things can do this? What type of agents could do this? Well, certainly if we take a look at just defining these into two major categoricals, we have drugs and devices. The drugs that could do this, I have listed for you. The likelihood of this being a drug-induced event is very very low. The reason for that is that the drugs would have to be given repeatedly. Characteristically, I'd have to be giving you the spiked doses that would have another host of effects, we call a constellation of effects. This would be notable and you wouldn't tend to see uniform effects based upon the way the drugs were given. In other words, drugs being given in different doses, at different times might manifest distinct effects in different people but also not had this particular pattern of presentation. So we can take the drugs and say: of those that we would say we're probably most notably those that are anti-tumour drugs like cisplatin and carboplatin. And probably the organic solvents. Once again these drugs are highly toxic. There'd be no way these individuals would present with this symptom alone and not present with another cascade or constellation of symptoms that would be indicative of exposure to these agents.
[5min56s] Which then brings us down to the idea of devices. What type of things could it be.
Well, it could be subsonic stimulation, it could be ultrasonic hypersonic stimulation. it could be a combination of both or it could be some type of microwave or electromagnetic pulse. The idea is that it could be all of these things. These are not mutually exclusive and very often devices can in fact be manufactured that will combine one or more of these different types of phenomenon to induce a percussive effect. This is not foreign as well. We understand that during the 1970s and 1980s a number of countries were examining the idea of electromagnetic pulse devices, sonic devices. Some of these have gone sort of mass-market production, some of these are commercially available even today as Dr. Balaban will illustrate to you. These are purchasable direct off the shelf. Moreover, we know that there have been a lot of dedicated efforts by nation-states and including from non-state actors that have tried to get work in this area, primarily to create weapons of mass disruption. And we see these being used for example with varying success on crowds, small aggregates of people and against individuals. But the problem is, very often, the older technology required fairly large-scale devices to implement this. However, with the sophistication of the tools that we have, we're now able to see this being shrunk down like so many other things. I'm looking at an audience of group of people, a variety of ages. Remember those first cell phones at about the size of a Volkswagen. We felt really good, “yeah I'm on the cell phone” you have to hold it like this. Now take a look at the size of a cell phone. What we see is compartmentalization and shrinkage of technology that increases its viability and utility of application. Next slide please.
THE INNER EAR
[7min23s]This is where we're talking about. Ladies and gentlemen, welcome to your inner year. So if we're looking at the ear, take a look at a slot on the upper left, what we see is that the ear basically has an external meatus, this thing out here and then there's a canal. There is a membrane which is the tympanic membrane, the eardrum to which are connected a series of bones which are called the ossicles. These things will move with a particular stiffness which will then intrude on to the hearing organ which is called the cochlea. So there are really two components of what the ear does. First is that the ear hears naturally. However, we also have to understand that the secondary component of what the ear does is the organs of balance and orientation. These referred to as the vestibular apparatus and they include the semicircular canals or the three looping canals and the saccule and ampule as you see here. Now, these are highly vulnerable organs to a number of different things. They're vulnerable to heat, they're vulnerable to pressure, they're vulnerable to sound. They're also exceedingly vulnerable to any other form of disruption that then caused a head trauma. So it's not unusual individuals have a jaw fracture or a mandibular fracture, maxillary fracture that very often you'll see secondary symptoms occurring as a consequence of inflammation. I'd bring that to you simply to tell you that these are exceedingly small structures that are exceedingly vulnerable to a variety of different injuries and insults. Moreover, take a look at the structure of the inner ear. The inner ear provides a mechanism by which a variety of different pulse stimuli can be amplified. Now, if we're looking at where damage can occur particularly with regard to hearing loss, we're mostly looking at this larger organ here called the cochlea. It's a semi-stiff organ, there's fluid in the middle and we know that various types of auditory stimuli can disrupt the cochlea and its function, sheer the hair cells, induced damage. You would see hearing loss with that. Next slide please.
What types of pathologies would you see, you'd see inflammation both locally and then more distally, you see hair cell damage and hair cell death. These are the organs for example in the cochlea that are sensitive to disruptions of the membrane that then transmitted, transduce the necessary stimuli for hearing. You would see membrane scarring and any of the membranes that were affected. You ‘d begin to see neurological damaging. Realistically, we know that we begin to see neurological damage as a consequence of two things. Number one, that the nerve itself is directly damaged, because of some insult to the nerve. Or number two, we then begin to see is if you're damaging the sensory organs of the inner ear you're seeing changes due to what is called excitotoxicity of the nerve. In other words you're overstimulating that area of the inner ear,you're hyperstimulating the nerve, as the nerve becomes hyperstimulated, you then see a disruption of neurological calcium and with the disruption of calcium you then get something called excitotoxity. Once that nerve becomes excitotoxic, characteristic is to be giving to see changes occurring upstream. This is just basic neuropathology. Next please.
MECHANISMS OF EFFECT - DRUGS
What type of things can do this. Well, again a host of drugs could do these types of things but we have to rule these out because we're not seeing drug like effects. Number one. Number two, we didn't see a constellation of signs and symptoms from these individuals that would be suggestive of some type of pharmaco-toxicology. And number three, the long-term effects really do not match what you would tend to see with either cisplatin or organic toxins. So as a consequence of that we can rule this out. Some of the early hypotheses were well perhaps these individuals were exposed to one or more of these compounds either directly or indirectly. Is it possible? Yes it is possible, might this have been a beta test where there was some priming or synergistic effect where individuals were exposed to low doses of these drugs? Yes. But these drugs were non recoverable as well. Moreover that didn't seem to be any other physiological signs that would suggest that these individuals received a high enough dose of these drugs to do the job. So we can rule these out. Next please.
"Mechanisms of Effect
"Sub-/Ultra-sonic Stimulating Devices"
"Pulsatile/tonic delivery of inaudible sonics"
[10min52s] What about sonic devices and/or electromagnetic pulse and microwave devices. Well, there's a number of different things that could be done here. Realistically, would you see is either pulsatile or tonic delivery of either sound pulse, particular a hypersonic pulse that would begin in the subsonic then translate through the sonic and into the hypersonic range. And/or you can engage some type of electromagnetic pulse, microwave pulsing that could then affect these symptoms in a very similar way, these signs in a very similar way. You would get over stimulation of hair cells, clearly with any type of sonic delivery. You would get hair cell fatigue breakage and death, you would get scarring and denervation.
[11min27] But you would also see that if in fact it was a hypersonic pulse and/or an electromagnetic pulse. You would then begin to cause cavitation in anything that has a fluid medium in it. Which would include any one of the vulnerable organs of the inner ear, the cochlea included. But most notably those that would concentrate this type of an energy pulse mode most directly. In other words, an acoustic or an electromagnetic lens. Are there structures of the inner ear that can do this. Next slide please.
The auditory features you would see if we're just limited to the auditory system would be these.
Note - Slide description:
High frequency hearing loss (~4000 Hz “muna”)
High to low progression (3-6 KHz spread, with < 1KHz spread)
However this was not noted as you saw in the earlier data. We're ruling out the idea that this was just an auditory assault. Next slide please.
So if you're going to engage the diagnosis for this and you're thinking, well, could there have been some means with focused energy that would then produce the signs and symptoms that we're seeing in these individuals with the statistical significance as was demonstrated here. What might be the viability to do such a thing. Well, you heard that audiological testing suggested that indeed these individuals were exposed to something but there's no long-term audiological or hearing changes. Pharmacological, toxicological recovery early on did not demonstrate that there was in fact any toxic substances or pharmacological poisoning. Cochlear imaging is difficult to do. Biopsy and forensic anatomy can certainly be done after the fact but your most reliable tests are those that are used in neurosensory defect. Those tests that as you saw earlier will determine the function of those nervous systems that are involved, in vestibular apparatus, balance, orientation and position. And in fact that's exactly what we saw. However, there also seemed to be some mild cognitive changes that were initially somewhat high and then tapered off and then some that were a little more progressive and that were more persistent. Is it possible, as you heard earlier, that the primary effect was localized to the inner ear and you're seeing secondary effects, what we call sequelae, with the individual's levels of cognition and emotional challenge then disrupted by the fact that they were highly vertiginous?
Yes, absolutely. I mean look, in a previous life, I flew airplanes for a while. And I got to tell you I mean one of the things that happens if you put individuals in a spin or an unusual altitude, it is exceedingly disorienting. Pilots and aircrew are trained to be able to function cognitively and with emotional stability and unusual environments that disrupt their positional sense. You recognize that. One of the most curious phenomenon is when an individual is exposed to either spinning or tumbling, very often what you'll find is cognitive deficits that will persist for several minutes to hours after that exposure. The longer the exposure, the longer the cognitive deficits occur. What type of cognitive deficits? Most notably with regard to information transfer, information assimilation and synthesis and the ability to then process information in a proactive way. And if you think about it, it almost makes sense. As you heard earlier from Dr. Hopper. It obtains. The issue here is simple. If I have to concentrate very very strongly on orienting my environment to what is up and what is moving around, it becomes exceedingly difficult to do anything else. We can tell you that one of the things we use very often is something called a branny chair. We'll put an individual on a spinning chair and then we'll ask them to do various tasks both during the spin and after the spin. And they become so disoriented as a consequence of loss of their vestibular senses and their positional upright and/or processional surround that their cognitive capabilities seem to be grossly, grossly impacted. Almost to the point that you are now saying this is a cognitive, a full cognitive defect? Now clearly when everything returns back to normal for these individuals, the cognitive defect then tapers it, diffuses it or damps over time.
But you do see similar phenomena with regard to cognitive blunting and cognitive defects in individuals who have profound Meniere's disease, which is an inflammation of the inner ear that then causes vestibular and semicircular disruption. Not only these individuals are positionally disrupted with vertiginous defect and dizziness, but they're also cognitively disrupted because the ability to process information inclusive of things like upright orientation, interactions with others then induces as the neuroscientist Antonio Damacio says a feeling of “what happens”. It is anxiogenic, it produces anxiety. If you've ever been dizzy, if you've ever had vertigo, you know that this is a very unsettling experience. And the phenomenon of that itself can be cognitively blocking. So could this be focused to the inner ear as a primary pathology, that then caused a secondary reactive or manifest changes in individuals ability to process and engage cognitive information transfer and capability? Yes, certainly it could. But could it be more, could it be that in fact you are also seeing an indirect or direct effect on the brain itself? Next please.
[15min59s] This is the idea of targeting the brain by accessing the periphery. Is it possible that what we're seeing here is not only a form of traumatic neurological injury to the ear but a communicating neurological injury that was then able to evoke indirect or direct effects on the brain? How might that happen? Well, again, there are a number of different things that can do this. We've talked about a variety of different pharmacological agents that co-present with some initial ototoxic or auto pathologic effects but realistically are working more in the central nervous system. But once again we can rule these out. The reason being is we're not seeing the recovery of these agents in blood, lymph, cerebrospinal fluid nor are we seeing the constellation of effects in the brain that would be reflective or indicative of this type of pharmacotoxicology.
However, if we then focus more on the devices, there are a number of different things that could work on the brain directly and/or affect the brain indirectly by working through one or more of the sensory portals. These include sonic generators, electromagnetic pulse generators and although not necessarily pertinent to this discussion, something I do want to bring to your attention is nanoparticulate matter and this is becoming increasingly a problem because as Jen Snow and I are working on this is now aerosolysible. The idea of aerosolysible nanobots has become a reality. So the idea of being able to utilize nanoparticulate matter as a neuroweapon now has become in fact real.
[17min25s] What are the possible mechanisms of effect? Whereby you could get an indirect or direct action into what's called the supratentorial space. The space above the tentorial membrane essentially the brain. Well, I think one thing it becomes exceedingly important to understand is that the brain is bathed in fluid, this is called cerebrospinal fluid. The brain is protected by a set of membranes, called the meninges and the meninges are basically threefold. The outermost and the most durable is called the dura mater. There's an in-between membrane that looks very much like the articulations of a spider web and in fact it's called the arachnoid membrane and it is filled with fluid called subarachnoidal fluid. And then this interfaces directly with the surface of the brain which is called the pia mater, the dear mother literally. That layer right on top of the brain is very very thin. The area of the subarachnoidal space is also a very richly vascular area. So what you now have is blood vessels that are interfacing with a fluid space existing in this kind of padded zone that looks like a spider web. So that particular structure itself might lend itself to some type of pressure-damage, inter-cavitation damage if we're looking at the meninges. But it's pretty hard to get those kind of waves at that level of effect through the skull. But what happens if you didn't have to go through the skull. What if you could go in the side door. What if you could create a pressure wave that was amplified through peripheral structures, that could then be communicated directly up into the brain. Essentially, what you're doing is now you don't have to storm the castle to go through the walls, you can literally sneak through the side doors and then go up to the parapets.
Figure: Inner ear - Brain. Slide by Dr. Giordano.
[18min54s] Let's go back to the inner ear. This is the inner ear. This is the brain. One more time. This is the inner ear, this is the brain. They live right next door to each other, they communicate, they communicate primarily through this region here. And this region here is called the Ductus reuniens (note: between red lines at the figure). And this area here where there's an actual communication that goes from the inner ear space that contains fluid called perilymph into the brain is called the cochlear aqueduct (note: between blue lines at the figure). It is an aqueduct. But what I want you to take a look at is the size differential between this fairly large vestibular space (note: shows area in green ellipse), would be basically called here as the foraminal area, the opening area, sometimes referred to as “the foyer” and the brain space. See the tube? This tube essentially, works as a venturi, it communicates fluid between these two spaces. One of the things we worry about for example for an inner ear infection is the communication of that infection into the brain space that then would produce a meningitis.
[19min56] But if we create a pressure wave here, we can disrupt the internal structures in two ways. Number one, primarily by amplifying it through the Venturi effect (note: relevant gif https://gfycat.com/delightfulunripebichonfrise) of creating cavitation in this structure here called the ductus reuniens, which then affects the saccule, the ampulus here, the utriculus. And/or by then creating an effect that would then communicate upward into the brain space by creating a cavitational wave that goes up through the cochlear aqueduct directly into the cerebrospinal fluid.
Now recall the cerebrospinal fluid bathes the brain. So what you would tend to see is injuries that occur in around the space beginning here, that could then cause a more disruptive effect as you actually disrupt the flow of this fluid. This fluid moves. Any cavitation in this fluid is going to be disruptive and it can create something which is known as “communicating hydrocephalus”. So now what's happening is you're actually getting a change in the level of the fluid because of bubble expansion, bubble collapse. This continues to communicate, it doesn't disrupt the flow of that fluid, but it can produce neurological sequelae, both short and long-term. The other thing that that can then do is that can produce a lot of change in the way the brain resorbs its blood flow, because this particular mechanism also affects the way blood is exchanged between the brain space and the vascular space. But the vascular space is also a portal by which peripheral disruption can then lead to central disruption. Next slide please.
"Mechanisms of Effect
Focused cavitation in fluid media | Perilymph - Sub-arachnoidal media"
[21min11s] So clearly if we're looking at the paralymphatics we can see that once again disruption of the paralymphatics, as we said earlier, can communicate into the brain space. It can also communicate up here into the subarachnoidal space because we know that the paralymphe will communicate with the CSF via that particular aqueduct. But once again we have blood vessels that are embedded within this subarachnoidal membrane that then interfaces directly with the substance of the brain. If we disrupt that fluid around the brain, could we then create a disruptive pressure wave by cavitation into these blood vessels, that would then be communicated into the brain space by both the paralymphatic CSF communication and the blood space? Yes we can. These things are essentially talking together. Next slide.
"Mechanisms of Effect
Direct and/or Communicating Effects"
[21min56s] So if we look at these communications what we can see is that any type of communication here into the subarachnoid space is capable of inducing a variable pressure wave, a cavitation wave, inclusive cavitation damage at a variety of different brain locales. We know that one of the things that this can then do is that can actually disrupt the integrity of the tissue because you're now increasing two things: number one, localized pressure, which then actually creates a traumatic event, which can then lead to axonal shearing and vascular effects which can then disrupt the blood flow to the brain. Disrupt the blood flow to the brain can then lead to microhemorrhagic infarcts, small level blood blood flow disruption, small areas of necrosis in the brain and this would then be more long-term. So clearly one way we could affect the brain through the inner ear is through the fluid medium that occurs via the inner ear directly to the subarachnoid space affecting the fluid medium that surrounds the brain and thereby causing a disruption to the brain structure directly.
Mechanisms of Effect
Focused cavitation in fluid media: Blood
[22min47s] But we can also affect the blood. And there's a number of different ways we can affect the blood. Certainly we can engage the inner ear and most of the pathology we're seeing here with this embassy encephalopathy would suggest that the inner ear provides for us an acoustic or some other form of energetic lens. This is going to concentrate this type of information creating disruption primarily in the vestibular area in and around the foyer that would then affect the saccule and the ampule. This would then disrupt the function of the inner ear, this could produce a cognitive constellation but at the same time could have a secondary disruptive effect, where it's now creating a cavitation wave that spreads throughout the paralymphatic fluid, communicates via Venturi effect up into the cerebrospinal fluid space, disrupts the flow of the cerebrospinal fluid in the subarachnoid space and thereby can also disrupt the vasculature.
But could you disrupt the vasculature directly, could you incur cavitation changes in some area of the vasculature that's going to affect both the inner ear and the brain? Oh yes you can. This is the area in and around the inner ear and what we can see is that there is a direct concentration of blood vessels - once again take a look at the upper left-hand portion of the slide - this shows the arterial supply to the inner ear, the utricle and the saccule. This is supplied by the anterior vestibular artery which forms a direct connection to the basilar artery which then communicates the cerebral arteries, most notably the middle cerebral artery. The middle cerebral artery branches up into the brain and has what's called here as this lacunar effect, in other words through these deep penetrating arteries that go into the brain space. These are exceedingly small vessels and the concentration of pressure within these vessels is exceedingly important to maintain a variety of neurological responses and cerebral vascular responses. These things will change as a consequence of local pressure and they'll alter the blood flow to maintain stable pressures across the brain space. Brain is highly vulnerable to these types of things. But if you disrupt the flow of arterial blood, you're going to get two things. Number one you get a compensatory arterial response and going to see changes in perfusion that'll occur in the vascular site. If this occurs as a consequence of bubbles what you are essentially producing here is microemboli. Can the microemboli lodge here in these lacunar vessels to create lacunar infarcts, microstrokes? Yes indeed they can. Can you get disruption of the brain space directly by disrupting the arachnoidal membrane, by disrupting the fluid that exists in the arachnoidal membrane by disrupting the fluid of the paralymph in the ear? Yes, you can. Can you do both at the same time? You betcha. What would the effect be? Well, clearly, if you're disrupting the inner ear directly by affecting the foyer, by affecting the utricle and the saccule by virtue of a pressure wave that then creates some type of cavitation within those structures that are fluid filled structures. You are going to disrupt, otolithic effects and you're going to get a change in the balance organs and balance function. Could that lead to problems with regard to cognitive processing? Absolutely. But based upon the structure of the inner ear could you also then begin to cause neurological changes and neurological damage? Yes, that's a possibility as well. You could certainly begin to cause degenerative changes at the innervation of the inner ear that could communicate along the cranial nerves, then have a neurodegenerate change. Is this easy to determine? Not necessarily, but certainly it could be done by virtue of certain types of imaging and certain types of nerve conduction velocity testing.
[25min59] But what if he didn't have to affect the nerve itself and you can get directly into the brain. The same pressure wave that would affect the utriculus and the saccule could indeed create a pressure wave with inside that foyer that would affect two components that would directly and indirectly assess the brain. The first direct effect being the communication through the paralymph of cavitation disruptions that then enter through the cochlear aqueduct to profuse the subarachnoidal space and cause a disruption in cerebrospinal fluid. And the second which would be a disruption of the vasculature here in the arterial blood supply that would then communicate back to the basilar artery and communicate up with cavitation in the blood flow to the brain. So what you see here is converging pathologic effects. Disruptive pathologic effects. Next slide please.
How would look to assess these types of things. You've already heard this, I'm not going to repeat the information. Dr. Hoffer’s group did a wonderful job in neurocognitive testing, neuroimaging, Clearly if you wanted to look a little more deeply, you have to take a look at some of the forensic anatomy (...). But you could also model some of this work, vivo, in vitro and with computer simulations. Which becomes probably the most accurate way to take some simulacrum in a phantom or in some other type of situation that would then model what these effects would be on the mammalian ear and on the mammalian brain. Of course for that our next speaker Dr. Balaban will discuss some of the work that he's done to empirically demonstrate what these findings not only are but could be based upon not only a type of image we see here or the type of image that we would then see if you were to increase the frequency or change some of the electromagnetic pulse. And next slide please.
[27min27s] So based upon that, what's the take-home messages I have for you. Like anything else let's go through a process of elimination. We have to go about this somewhat deductively. Because we have a set of individuals who've suffered this particular constellation of signs and symptoms and we recognize that from that these are the things we're seeing. What types of changes could we be seeing in the peripheral and central organs, neurosensory organs and in fact the brain that might be indicative of this and what could do it. Is it possible that drugs alone could have done that. Well early on in our discussion we ruled that out. Is it possible that ultrasonics could do this. Yes this is very likely and highly probable. Is it possible that electromagnetic pulsing, microwave pulsing, in some way could do that. Very possible, highly probable. Is it also possible there may be some combinatory approach, a beta test if you will to see if we give drug first at a low dose or ultrasonics at a low dose coupled with some type of electromagnetic pulse, microwave dosing in some combinatory form, could these be worked. Quite possible with very positive explanatory value.
In other words if someone put a gun in my ear and said which one do you think is going to produce this constellation of effects that we saw in those individuals who are most affected not only in Cuba but more recently in China, I would tend to think that what you're probably finding is this last one. Whether or not drugs or some other form of pharmaco-toxicologic agent we use I think remains dubious. But certainly there are devices that are widely available that we also have know have been dedicated activities in the neural weapons space by a variety of nation states. They would be capable of doing just this type of thing. The inner ear provides a locus forum for this to then be conducted in such a way to manifest these effects, but it's not the inner ear alone. It could occur through the sinuses both the ethmoid and the sphenoid sinuses. It could occur through the hard palate of the mouth. Any one of the vulnerable amplifying spaces of the head could do it and certainly what becomes important is how such a weapon could then be focused and utilized in those ways to be able to create this effect. Might it be once again that this was something it was serendipitous, sarcastic, that this was some type of vermin protecting agent or device that was simply in those rooms which these individuals were then suspect. Perhaps. Is that likely? Not very. The reason for that would be that many others would have these signs and symptoms, for one, number two there would be some engineering artifact which would then be attributable. Here's the device, this is what was being used for and there would be an attribution or custodial record for that. Absent that, once again by virtue of implication, this is intentional, this is directed, there seems to be a beta test of some type of a viable neuroweapon that utilizes one or more of these modalities for its effect. Next slide please.
That's all I have for you. Clearly what I'd like to leave you with is speculation. Speculation based upon the facts of the case, speculation based upon what we know about the weaponology and or at least the device-ology. Speculation about what we know about what the pathology is and could be and how this would work. So what I'm asking you to do is something quite simple. Take the facts of the case based upon the findings that were presented to you by Dr. Hoffler. Want you to take the level of possibility and probability in terms of what the viable structures are that could communicate such effects in real life terms. And then pair that if you will to our next set of speakers will not only talk about what the empirical findings are that could reproduce this in a model scenario, but how this could also be leveraged geopolitically with regard to the viability of an increasing capability confidence in consideration in neural weaponology. Thank you."

"Acute presentation of an acquired neurosensory syndrome"
Hoffer M., Levin B., Snapp H., Burkirk J. and Balaban, C.
University of Miami, Miller School of Medicine, University of Pittsburgh
“First of all I'd like to thank the Donovan group, SOFWERX, SOCOM (USSOCOM J5) and the group for inviting us to speak. This is a very important topic and we're honored to be here and present today. So thank you very much. So these are the author affiliations for the group, these are the views of the authors, not the views of the government, not the views of the Navy, not the views of my University. So in February of 2017, I literally got this call: "this is the State Department, we have a problem". So what happened was individuals began experiencing symptoms - late in 2016 - of ear pain, tinnitus, dizziness and cognitive issues. The profiles were: all experienced a loud noise or pressure phenomenon before and during the symptoms. All were members or family members of individuals stationed with the U.S. diplomatic mission in Havana Cuba and the sound was localized and followed the individuals. In fact, if they opened the door to the outside the sound immediately went off.
So thirty five individuals who were symptomatic or at risk were evaluated at our facility, at the University of Miami. Twenty five who were exposed and had symptoms and ten who were not exposed but lived with the individuals who were exposed and were in the houses when the individuals were exposed. We also saw a hundred and five unaffected Embassy members. We evaluated those people in Havana. They were largely selected by the Embassy to see us, however we did ask to see all the Marines who are assigned to the Embassy detail ourselves.
So all the individuals at University of Miami underwent a standard history and physical with an additional targeted neurologic history and physical. They all had eye movement tests that included tests for a nystagmus, smooth pursuit, saccades and anti-saccades, optokinetic response and vergence responses. They all had standard audiometry and then a subset of individuals had additional vestibular testing and additional neuropsychological testing. We were seeing these individuals as patients. Only clinically relevant data were collected and all testing that we did had to be justified and approved by insurance. New individuals we saw were acute and unaffected by the influences of time, variable pre-treatment modalities, compensation - they weren't seeing us for workers comp - and media attention. So when we saw the individuals they did not know what they were supposed to be presenting with, because at that time the media had not publicized what the effects were. So they came to us without the ability to “kind of know” what they should say.
The prevalence of the symptoms in the unaffected groups and the affected group were analyzed with a two-tailed Fisher's Exact test, this is going to be explained, going to be used in the following slides and due to the non Gaussian distribution we used the lower fifth percentile, and the lower one percentile of performance to judge abnormalities. And this is up there because there's been a criticism that some of the tests that we're going to present, people that have anxiety or people that have other disorders have these abnormalities. But not to this degree. So that counters that argument. This is a population study in 140 total,105 in Cuba and 35 in Miami distributed as I reported earlier. So here is the presenting symptoms of the groups. So the affected group you can see, they had a lot of, a great number of them reported dizziness. This is reporting when they saw us in Miami. Cognitive disorders in about half. Hearing loss in one-third. Tinnitus one-third. Ear pain in 20%. And none of the ten individuals who were in the houses at the same time but were not affected had any of those symptoms. In fact, except for headache which is a common symptom in many individuals, the affected group had statistically more symptoms than the unaffected group. Notice said again 96% of the affected group had at least two symptoms and 64% had at least three symptoms. Again, symptoms being dizziness, cognitive disorders, hearing loss, ringing in the ears, pain in the ears or headache.
This is the data by group of the 25 affected individuals. So now we're not talking about the ten that weren’t affected, the 25 that were affected. 88% of them had an abnormal subjective visual vertical testing, 52% of them had abnormal anti-saccade testing, 83% had Chair impulse testing. You can read the slide yourself and 92% had at least one VEMP abnormality.
And let me explain: subjective visual vertical is a test where individuals are told to take an object that's off-center and make it point straight up. Vestibular Evoked Myogenic Potentials (VEMPs) are tests that explore how the organs of gravityception both either the utricle or saccule, how they respond to sound. If you have an abnormal VEMP or an abnormal subjective visual vertical it's telling us that the organs of gravityception, which are the utricle and the saccule, are affected. So what we're seeing is that if you take the subjective visual vertical and the VEMP data, every one of the affected individuals, all 25 of them, had at least one test that was abnormal telling us that their utricle or their saccule in least one year were affected. So the organs that tell you that you're up and down were affected universally in this population. That set of organs is extremely important because that gives you a perception of where you are in space. Not where your head’s turning but how your body is oriented to gravity. And when these organs are affected, when these organs are abnormal in this population and in other vestibular populations, individuals are severely affected. Because if you don't know which way up and down is, you're not really good for anything else. So these are the definitions, again you can read them, but what we want to point out is that we're taking abnormalities that are extreme. So subjective visual vertical abnormalities in the lab are 1.5 to 2.5 degrees, we're only accepting over 3.2 degrees and on down. Cervical VEMP errors abnormal if amplitude is less than 100 microvolts or greater than 35% amplitude asymmetry between the sides, again those are much stricter criteria than the standard vestibular lab uses. So if you see arguments that “well people have these abnormalities with other disorders”, not to this extent. Not to the extent we're reporting. And again that's important because there was a recent article in JAMA where someone said “well lots of people have these abnormalities”, well not to this extent.
So there were also some cognitive and neuropsychological symptoms that Bonnie Levin who's an (...) physician did this data, so I'm reporting her data. Cognitive fog, inattention, problems retrieving information and increased irritability. And when you did the testing they were below the expected level for verbal fluency, for working memory and for sustained attention. They had difficulty with auditory processing and difficulty with increased levels of cognitive load. Now while this pattern of abnormalities can be seen in other populations, at least according to our neuropsychological colleagues, the unique pattern seen here is unique to this group. So we have a unique set of vestibular findings and we have a unique set of neurocognitive or neuropsychological findings, and that combination is not seen in any other group of patients.
The exposure is unknown today, we're going to talk about that a lot this morning. It could be ultrasonic energy, it could be microwave energy, it could be one of a variety of things. Dr. Balaban is going to talk a lot about directed energy, can produce cavitation bubbles. I think Dr. Giordano is gonna speak about this as well. Bubble formation and bubble bursting can produce damage in any hollow space and candidate spaces exist right in the area of those vestibular (...). So I use the term utricle and saccule, I think dr. Giordano’s got a picture of those in his presentation, and those organs sit right next to areas where cavitation can occur. So it makes sense that if I'm getting a sound in and it cavitates in that area it's going to affect those two gravity organs, the utricle and the saccule."
IS IT TRAUMATIC BRAIN INJURY (TBI)?
"The aura of mild traumatic brain injury. I use this term because if you really break down the term mild traumatic brain injury, it's simply injury to the brain that is mild and that occurred from trauma. And it's synonymous with concussion, nothing more. So if you say you ‘ve a sprained ankle, you have a sprained ankle. If you say you have MTBI, all of a sudden you're some mystical creature who crawled out out of the lagoon. It doesn't make any sense because again medically, it's just traumatic damage to the brain that's mild. Just like traumatic you know damage to the ankle that is mild.
So one important question we're always asked, we were asked by the State Department, we were asked by DoD, we were asked by CDC and we were asked by NIH is “is this what you saw in these Cuba patients, is this traumatic brain injury. This is the definition of traumatic brain injury as determined by the DoD back in 2005, reaffirmed in 2009 and finally reaffirmed most recently in 2017. Individuals suffer a blow to the head. The individual has a period of altered or loss of consciousness of less than 30 minutes, some groups not the DoD but some groups will accept less than 60 minutes. Individual has a sequela, they have a finding after that. And the same individual does not have intracranial bleeding, does not require surgery for the injury or acquiring an intensive-care state. Essentially, synonymous with concussion. Now I will say that the blow to the head could be either a natural physical contact with the head or could be a pressure sensation. It doesn't have to be physical contact. So that's what the DoD said a year ago and still stands by as their definition for mild traumatic brain injury. Now it doesn't need to be our definition but it's their definition. And it's one that we use in a lot of our work because I was in military for 21 before this, so I'm a good soldier or good sailor. So this is what mild traumatic brain injury looks like.
If you look at people that were injured in a war, this is data from when I was in San Diego. The acute group was collected acutely, when I was deployed in Iraq. These individuals were all within three days of having had an injury in theater usually a blast injury. Subacute group was collected in San Diego when I was there and the chronic group also at San Diego. To give you some idea about how much traumatic brain injury was produced, the number of individuals in the acute group is 88, the number of individuals not shown here in the subacute group, but this is all published data already, is seventy and there's about sixty in the chronic group and that was collected subacute and product in San Diego over a two-month period of time at the height of the war in Iraq. A lot of individuals were coming back with brain injury.
So notice that dizziness is the most common symptom. At all time epochs. Acutely, subacutely and chronically. Different groups of people but again very similar presentations. So notice that dizziness is there 98% of the time almost universally in the acute group and it falls off but not very much. Headache is the next most common. See it at 72 percent, 82 percent long-term. And then you can see vertigo and hearing loss. So for those of you who do vestibular stuff, dizziness in this case was unsteadiness, being off-balance. Vertigo is actually room spinning phenomenon. So there was a lot of off-balance, not as much room spinning and not as much hearing loss. And notice the high prevalence of headache. This is the ROC curve, again published data that from from Carey Balaban and I on our group, where we take a pair of goggles, the same pair of goggles that we applied to the Cuba individuals, Kerry's going to talk about these a little bit later, and these are the key factors: anti-saccade error rates predict dif. saccade error rates and it had even post-testing error rates. Okay notice that the visual vertical, vemp testing are not on there, they're not the key indicators for TBI, they are the key indicators for the group in Cuba. So is this traumatic brain injury? The definitions don't match, the findings don't match. Anti and predictive saccades and head thrust tests are used for MTBI, whereas odourless findings are seen in those with this syndrome, so different findings. There's a much higher incidence of headache in the mild traumatic brain injury, I showed you anywhere from 76 to 82 percent versus the low incidence in this group 32%. And there's a difference in neuropsychological testing outcome as well that Bonnie Levine showed. So I'm not we're not saying this is not MTBI but this does not fit the military definition of MTBI as subscribed a year ago.
[14min08] So what is it. It's an acquired neurosensory dysfunction with essentially universal otolithic disorders, some additional vestibular findings and a unique pattern of cognitive findings. Remember, I described for you that otolithic abnormalities, utricle and saccule, mean that the individual has an abnormal gravity sense. Now, the site of injury could be limited to the inner ear with secondary cognitive dysfunction. Because when you don't know what upright is. Essentially when you're being chased by a tiger in the jungle and you fall down, you ‘re dinner for the tiger. It really doesn't matter if you can balance your checkbook or function cognitively. So it's quite possible, we have data in our lab with Carey and Bonnie as well that show that if you have a dysfunction of what's up and down, you don't have a lot of mental energy left over for cognitive tasks. So the injury could be limited to the inner ear and the cognitive effects may be secondary as simply the inability to know what up and down is. Or there could be injury in multiple parts of the system, that remains to be determined. But we're working on that now because again if you don't know what up and down is, you can't do much cognitively.
Most importantly this is a real physical injury and those truly affected. The 25 individuals we saw had objective findings of a disorder that came acutely from what happened in Cuba. I'm not talking about the word well, I'm not talking about people who presented later somewhere else. I'm talking about people who came to Miami, they didn't know what they should report and they had objective findings. You can't fake a VEMP test, you can't fake a subjective visual vertical. You can fake it but it will be apparent to us that you're faking it. So the tests were real and they were objective. And that's important because the 25 most affected individuals and we're not sure if anyone got affected elsewhere in the world until we do this kind of testing on them, but the 25 affected individuals are often accused of malingering or exaggerating. I can tell you those 25 are not. And that's an important message. Also importantly, these findings suggest the ability to screen potential cases. So otolithic tests, the test for whether you are up and down are easy to transport and quick to perform. And a quick cognitive screen could be easily designed. And these screening techniques are critically important for distinguishing the word well. We already have at least 25 documented cases of word well from the truly affected. And the fact that these findings are known means, I mean it's going to call out groups, they should have been applied to anybody else who complain to this, and we feel that again, we can design a fairly easy screen and Carey is going to show you an additional part of that screen in his talk, to really determine who's affected and who's word well. Because now that it's out there, now that people know what they should complain of, now they know what the symptoms are and this is all almost all lay media attention, they can fake this stuff pretty easily and again we've had 25 people trying to fake it come to us and we've been able to rule them out. In any current or future evaluation of case, you should include at least this short battery as a screening battery, for what's going on.
So I'd like to thank a bunch of people because this work doesn't get done in a vacuum kaskus. We've been doing work with the Office of Naval Research, funded work with that office for many many years. They did not fund this work but they fund similar work. Fred Telischi is my department Chair who allows me to do this stuff and see these patients. Toni (...) is our Vice Chairman who watches all of our finances at Miami. Even more important for allowing me to do this stuff. Danna is my administrative assistant who scheduled all 35 of these patients from Cuba to Miami. Interestingly enough almost all the people who saw these individuals were Cubans that worked in our clinic. Constanza Pelosi is our research director, Aaron Williams is my research coordinator. The nurses, audiologists and support staff at the Miami Hearing Institute were amazing in helping us with these individuals and again we want to thank you for giving us a forum to present this and you know we think this is the true story, there are other stories out there, we know this is the real story of at least the acute individuals. Thank you very much”.
