The gamma wave could be related to image processing. Even if the retina deliver a continuous stream of pulse (Action potential), I think that one early processing performed in the visual cortex is to synchronize the visual data with a clock (Clock as defined in computer hardware). The signal is strong, easily detected with electroencephalogram because a large number of neuron (the entire visual field, approximately 1 million neuron) happen to be controlled by that particular clock. It seems that approximately 7 of these gamma wave can fit inside the slower clock. These clock are independent but can be modeled as "coupled oscillators". I would think that the visual cortex perform one visual processing one each gamma pulse. The processing involve feedback loop where the answer from the visual memory is feedback, in part or totally replacing, to the visual input. In other words, as the brain process a stream of though, the information from the retina is replaced by images generated as answer to previous query. After a few (possibly 7 in the timing example presented in the video), the answer is presumed good enough to be sent to other brain area.

Christian Gingras Vestibular Question...Can pppd or other inner ear issues show up on an eeg? What I mean is can an inner ear issue cause misfires in the brain due to the wrong signals being passed through ears, eyes, brain ect?

I would like to know what is the size of human neurone. I cannot find this information on the Internet neither on RUclips nor on Wikipedia. Can you help me?
Could you please give your opinion on this subject? How much is the damage in the brain by the technology used to project voices and pulsed electronics waves into the brain, for exemple V2K, REMOTE NEURAL MONITORING. I am asking because I am concerned about what the Brazilians are doing to me here in the Bay Area, they are projecting a technology and hating my brain even when I am in bed, I am feeling that my brain is very exhausted and swallowed. Please answer my question. Adriana Flores a victim of electronic harassment done by illegal Brazilian here in California.
Only thing I don't like about talks like these are that they impress people by focussing on the broadest and most obvious 'skills'--plasticity, conscious awareness--when there are a vast other number of feats that apparently organisations like TED and the RSA feel are too quotidean for the general public to digest. And this is a real shame: besides the grotesque exaggeration of plasticity that many popular authors have described, some of the most fascinating/mind-boggling/confusing/awe-inspiring 'computational' feats of the animal brain (including humans) is demonstrated in such simple tasks as avoiding the sugar bowl in reaching for the tea bags beside the recently boiled kettle. I reckon lectures for public audiences should start steering away from contentious and mysterious aspects of neuroscience in favour of developing really entertaining accounts of, say, the interplay between motor cortex, parts of the cerebellum and the vestibular system. I know there's already much of this in medical education videos. But I'd like to see more of this well-understood (or at least well-understood relative to speculative 'mirror neurons material) material becoming popular. At the least, I could have interesting party conversations about the 'miracle' of balancing a coffee cup in one hand while running to a meeting, rather than the banal hackneyed and pretty much useless discussions so many people seem to love striking up about 'neural plasticity' and 'consciousness', the latter of which seem to be not more more than signalling or posturing instead of being informative and born out of genuine interest in the world.
+Rawdon Waller, you're talking about "the grotesque exaggeration of plasticity" : I can see your speech writen here in youtube and you are just 100% totaly reacting to the talk. You are like water in a container. You are just almost totaly adpating the form of your idea to the form of the speech. Youre ideas are totaly plastic !!! I could almost say : youre ideas are totaly liquid. How is that possible ? ( sorry for my english, i'm french ) Hence I don't think the plasticity of brain is exagerated ( maybe it's even underrated ). I can precise the "mental" is plastic or liquid. Brain may generate these properties at a level or another. If not, what does ?
Too much information about an important subject is actually wonderful thing!
The pace of brain research is such that we are learning things year on year. I can't even imagine what they will know say, a generation from now.
Yup.
50 years ago, what we know now was pure science fiction.
Well conveyed, enjoy listening
Thanks for this lecture! Important data love it!
What an informatie lecture. Thanks.

Did you record this video with a toast machine sir ?
haha
is very important learning how work our brain i like know
thanks for the vid :-)
my i5-2500k that plays Crysis owns this
tNx
thanks ::)
TO DR LANDRUM....IF YOU TOOK THE TIME TO SPELL CORRECTLY,I MAY HAVE CONSIDERED YOUR RESPONSE!

There is no existing compelling evidence that contentiousness is a bi-product of the brain...
Because science, Mike!
Brains - something coincidence theorists and liberals and Reddit atheists do not currently have.
