Document Summary

Temporarily holds data we may want to remember. Brain wave patterns and the eeg: electroencephalogram, outer 2-4 mm, gray matter, 4 general classes of brain waves, used to diagnose sleep disorders, also to demonstrate brain damage: flat line compliment/replace eeg. Consciousness: continuum: alert -> drowsy (lethargic)-> stupor -> coma. Nightmare (remember)/ night terrors (more: rapid eye movement (rem) sleep follows, gradually stages 1-4, sleep becoming deeper, bp/hr severe, don(cid:495)t remember(cid:524) muscle paralyzed. Normal dreaming. (cid:573) wave on eef: eyes moving rapidly under eyelids, most skeletal. Penile/clitoral erections: bp/hr/respiration rate increase, use of o2 by brain. Infant 16 h/night -> 8 h young aults -> level->elders less: rem 50%->25% by age 10. Stage 4 decreases from birth, disappears by age. Importance of sleep: slow wave sleep (stage nrem) restorative: neural activity winds down. More prevalent in sleep-deprived depressed, personality disorders: rem: brain analyzes day/solves emotional problems via dreams. No rem-: rem may also (cid:494)unlearn(cid:495) accidental, meaningless, repetitive communications from cortex.
