Document Summary
Tononi"s integrated information theory (itt) of consciousness: conscious states are highly differentiated, conscious information is deeply integrated. Interactions in the brain create various states of consciousness. = extent to which brain is integrated. Itt explains why consciousness can occur without stimulation, as in rem sleep. Assumes that all beings can achieve some level of consciousness. Itt provides a helpful step forward in study of consciousness. Attention is important (but not essential) in controlled states of consciousness. Repeat once a day (cycle over ~24 hours) Continue even in the absence of external cues. Circadian rhythms are regulated by multiple internal clocks. Sleeping enough is important to ensure optimal cognitive functioning. Jet-lag, shift work, and ignoring one"s own sleep pattern results in difficulty sleeping and less efficient functioning. 4-5% light sleep, muscle activity slows down, occasional muscle twitching. 45-55% breathing pattern and heart rate slows, slight decrease in body temperature. 4-6% deep sleep begins, brain begins to generate slow delta waves.
