Is Consciousness operating at a frames per second mode? As in cinematography?


Experts from this blog entry by Rob Bryanton @10thdim:


"Perhaps the most fundamental question neuroscientists are investigating is whether our perception of the world is continuous or a series of discrete snapshots like frames on a film strip."


"And with this article, we see interesting new evidence of an idea we've talked about before, that the brain itself is also operating at a certain number of "frames per second" rather than in a continuous undivided stream (...)"


"(...) Dr. Stuart Hameroff and his theories showing that consciousness works at a certain number of "bings" per second" "this leads us to some fascinating ideas about the relationship between this frame rate and what happens when this frame rate is out of sync with the body. We'll talk about this more in our next few entries, Time and Schizophrenia, Consciousness in Frames per Second, and Time and Music."

"Coherence Potentials" are "perfect clones" of potentials in two brain areas

Coherence potentials are for a group of neurons what an action potential is for one cell


Related to the Genesis of Thought. An electrical signature of thought.


As a complicated waveform is replicated in a nearby brain area a notion of entanglement in the brain is proposed

Scientists had previously discovered the phenomenon of "phase locking": the electrical activity of neurons in separate parts of the brain can oscillate simultaneously at the same frequency. This is like a brain signature designating neurons working on the same task. 


The phenomenon termed “coherence potentials”, was much more complicated than the simple phase-locked oscillations and always matched each other in amplitude as well as in frequency. They consisted of sophisticated waveforms that were replicated for instance at area 10 millimeters away. 


For example, if you smell a flower you have a very complicated activity pattern in a specific brain area (let us say « smell center ») that appears milliseconds later e.g. at the visual center.


Coherence potentials for a group of neurons are similar to an action potential for one cell in the sense that  a specific threshold has to be exceeded for initiation.

Coherence potentials encode simple human sensorimotor behavior. Parameshwaran D, Crone NE, Thiagarajan TC.PLoS One. 2012;7(2):e30514.



Here is a 2010 Science Update from the National Institute of Mental Health:


From Neurons to Thought: Coherent Electrical Patterns Observed Across the Brain



"Amidst the background hum of electrical signaling generated by neurons in the brain, scientists have found that local groups of neurons, firing in coordination, sometimes create a signal that is mirrored instantaneously and precisely by other groups of neurons across the brain.  These transient episodes of coherence across different parts of the brain may be an electrical signature of thought and actions."



Blog of one of the authors cites a subsequent paper where authors related these coherence potentials to simple motor behaviors in a human patient:

In figure C below we see among other the coherence potential for clenching one's fist.
