Clocks in the brain - How Consciousness Forms, 40 Hz Thalamus Clock

Excerpts from a Rober Pollack's book, suggested by a new article discussing Executive Attention, published by the AGI researcher Boris Kazachenko:

The Missing Moment: How the Unconscious Shapes Modern Science

The key topics include:
- The thalamus as a clock, 40 Hz and 1000 Hz.
- 0.5 sec delay after a stimulus turns into a conscious sensation
- clock's phase synchronizing to external sound stimuli
- incapability of brain to discriminate and feel consciously events shorter than ~1/80th of sec
- even a slight thalamus damage may cause deep coma - circuitry goes out of sync

Thanks Todor! That knol is still pretty raw, I'll have a new edit soon. The Missing Moment looks interesting, though a bit fruity (I only skimmed some of it). That excerpt is pretty good, but the format is atrocious. You can read most of the book on Google Books.

You're welcome!

Yes: font, background, abbreviations...

Thanks, but are you sure (I've been confused for other books). I can't find such edition, only the first 48 pages.

You're right, the chapter "Sensation" is missing there. BTW, I posted a new edit: "Executive Attention".
