Where is the major sleep center located? - ANSWER Hypothalamus
Hypothalamus - ANSWER secretes hypocretins that promote wakefulness and rapid eye movement
(REM)
Stages 1 of sleep cycle - ANSWER -lightest level of sleep, only lasting a few minutes
-gradual fall in VS and metabolism
-awakened, person feels as though daydreaming has occurred
-sensory stimuli (noise) easily arouses

-lasts 10 to 20 minutes
