1

EOG

Eyelids

2

EMG

Chin

3

Alpha

8-12hz
More prevalent when eyes are closed

4

Beta

13-30hz
Alertness

5

Wakefulness consists of

Alpha and beta activity

6

Stage 1

Theta activity (3.5-7.5hz)

7

Stage 2

Irregular
Theta
Sleep spindles (2-5/min)
K complexes (1/min)

8

Sleep spindles

Increased # = higher intelligence test scores

9

K complexes

Forerunner of delta waves
Isolated periods of neural inhibition

10

Stages 3+4

Delta activity (slower than 3.5hz)

Slow oscillations of less than 1hz (up state = inhibition, hyper polarization
Down state = excitatory depolarization)

11

REM sleep

Approx 90 min into sleep
Paralyzed

12

8 hour sleep contains

Four or five periods of REM sleep

13

Most slow wave sleep occurs

During the first half of the night

14

Sleep apnea

Inability to breathe
Snoring

15

Narcolepsy

Sleep at inappropriate times

Cataplexy (muscle weakness, sleep attack while conscious, precipitated by strong emotion)

Sleep paralysis

Hypnagogic hallucinations ( often terrifying)

16

REM sleep behavior disorder

Associated with slow wave sleep

Bed wetting (nocturnal enuresis)
Sleepwalking (somnambulism)
Night terrors (pavor nocturnus)
Sleep related eating disorder

17

Orexin is responsible for

Canine narcolepsy

18

Glomeruli

Where axons from olfactory receptor cells and mitral cells meet

19
