Chap 8-sleep Flashcards
(25 cards)
EOG
Eyelids
EMG
Chin
Alpha
8-12hz
More prevalent when eyes are closed
Beta
13-30hz
Alertness
Wakefulness consists of
Alpha and beta activity
Stage 1
Theta activity (3.5-7.5hz)
Stage 2
Irregular
Theta
Sleep spindles (2-5/min)
K complexes (1/min)
Sleep spindles
Increased # = higher intelligence test scores
K complexes
Forerunner of delta waves
Isolated periods of neural inhibition
Stages 3+4
Delta activity (slower than 3.5hz)
Slow oscillations of less than 1hz (up state = inhibition, hyper polarization
Down state = excitatory depolarization)
REM sleep
Approx 90 min into sleep
Paralyzed
8 hour sleep contains
Four or five periods of REM sleep
Most slow wave sleep occurs
During the first half of the night
Sleep apnea
Inability to breathe
Snoring
Narcolepsy
Sleep at inappropriate times
Cataplexy (muscle weakness, sleep attack while conscious, precipitated by strong emotion)
Sleep paralysis
Hypnagogic hallucinations ( often terrifying)
REM sleep behavior disorder
Associated with slow wave sleep
Bed wetting (nocturnal enuresis)
Sleepwalking (somnambulism)
Night terrors (pavor nocturnus)
Sleep related eating disorder
Orexin is responsible for
Canine narcolepsy
Glomeruli
Where axons from olfactory receptor cells and mitral cells meet
