Document Summary
Consciousness- oct 4 2015 chapter 5 part 1. Includes everything of which we are aware at any given time, our thoughts, feelings, mental processes, and events outside ourselves. Our awareness of ourselves and our environment. Most of us need about 7-10 hours, newborns need about 16 hours throughout the day. Often we are unaware that we"ve been sleeping. May have sensation of falling (hypnic myoclonia) or experience sudden jerks (myoclonic jerks) of limbs. Bursts of electric activity called sleep spindles and k-complexes appear. Heart rate and body temperature lower, and muscles relax. We spend as much as 65% of our sleep in stage 2. Rats deprived of rem or total sleep typically die within a few weeks. Function of eye movements (darting) is unknown. Individuals with rem behaviour disorder act out their dreams because brain stem structures responsible for the paralysis (ex. locus coeruleus) aren"t functioning correctly.
