Document Summary

Damage to the scn delayed sleep phase syndrome. Hebb believed that sensory information serves two purposes: to provide information, or what he termed the cue function of a stimulus, and to arouse the individual (the arousal function). A 4-hour delay in rhythms of sleep and temperature cycles, possibly caused by a mutation of gene (per3) involved in the rhythmicity of neurons in the. People with this syndrome are typically unable to fall sleep before 2:00 am and have great difficulty waking before midmorning. withdrawal of amphetamines leads to prolonged rem rebound, sometimes lasting up to two weeks, accompanied by vivid nightmares. Even alcohol, if taken in sufficient doses, leads to rem suppression. It is possible that the vivid hallucinations sometimes experienced in alcohol withdrawal (termed delirium tremens [dts]) may result from rem rebound intruding on waking behavior. Regular synchronous electrical activity occurs during the deepest stages of slow-wave sleep.
