[FRIAM] levels of consciousness

[Prof David West]

Yes, the subject line is a bit of a troll aimed at professed behavioralists.

Using a single quantifiable measure - degree of diversity in brain activity:

People have a 'baseline number' established when "awake" and "aware."

People asleep, under anesthesia, in comas, or in vegetative states, have decreasing numbers — "lower levels of consciousness."

People under the influence of psychedelics have larger numbers — "higher levels of consciousness."
