Document Summary

Narcolepsy-sudden, uncontrolled sleep attacks, immediate transition to rem sleep. Sleep apnea- breathing stops and restarts during sleep. Sleepwalking: usually during first 2-3 hours of sleep (stage 4) Night terrors: usually during first 2-3 hr of sleep (stage 4) We dream the most when the brain is active we dream more in rem than in non rem sleep. Brain activity is also higher during the final hours of sleep. Brainstep bombards higher brain center with random neural activity. Cerebral cortex interprets activity and creates a dream. Propose that dreaming and waking though are produced by the same mental systems in the brain. Antagonists - inhibit or decrease the action of a neurotransmitter. Brain creates compensatory responses(e. g. reactions that decrease heart rate) Drug tolerance always leads to significant withdrawal. If a drug does not produce tolerance or withdrawal, you cannot become dependent on it. Physiological dependence is the major cause of drug addiction.
