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
