The 100 ms time domain corresponds closely with the known brain physiology of consciousness, including brain rhythms in the alpha-theta-gamma domain, and event-related potentials in the 200–300 ...
Thomas Henry Huxley for example defends in an essay titled "On the Hypothesis that Animals are Automata, and its History" an epiphenomenalist theory of consciousness, according to which consciousness is a causally inert effect of neural activity—"as the steam-whistle which accompanies the work of a locomotive engine is without influence upon ...
The potential richness of conscious experience appears to increase from deep sleep to drowsiness to full wakefulness, as might be quantified using notions from complexity theory that incorporate both the dimensionality as well as the granularity of conscious experience to give an integrated-information-theoretical account of consciousness.

Reduced duration of sleep, as well as an increase in time spent awake, are factors that highly contribute to the risk of traffic collisions, the severity and fatality rates of which are on the same level as driving under the influence of alcohol, [53] [54] with 19 hours of wakefulness corresponding to a BAC of 0.05%, and 24 hours of wakefulness ...
