Brain & Behavior Ch 14

Front 1

measure of gross electrical activity of brain

Back 1

electroencephalogram (EEG)

Front 2

measure of eye movement

Back 2

electrooculogram (EOG)

Front 3

measure of the electrical activity of muscles, esp of the neck

Back 3

electromyogram (EMG)

Front 4

emergent stage 1 EEG is usually called __ sleep

Back 4

REM

Front 5

stages 3 and 4 are referred to as __ __ __ after the delta waves that characterize them

Back 5

slow wave sleep (sws)

Front 6

information supplied to cortex during REM sleep largely random and resulting dream is cortex's effort to make sense of random signals

Back 6

activation-synthesis theory

Front 7

environmental cues (such as light-dark cycle) that can entrain circadian rhythms

Back 7

zeitgebers

Front 8

circadian rhythms in constant environments (no zeitgeber)

Back 8

free-running rhythms

Front 9

brief periods of sleep (2-3 seconds) when subjects become less responsive to external stimuli

Back 9

microsleeps

Front 10

sensory tracts that mediate entrainment of circadian rhythms by light-dark cycles branch off from the __ __ and project to the __ __ of the hypothalamus

Back 10

optic chiasm, suprachiasmatic nuclei

Front 11

recurring losses of muscle tone during wakefulness

Back 11

cataplexy

Front 12

inability to move just as one is falling asleep or waking up

Back 12

sleep paralysis

Front 13

dreamlike experiences during wakefulness

Back 13

hypnagogic hallucinations
