chapter 60 - exam 5 Flashcards
(23 cards)
desynchronized brain waves
excited, irregular, no detectable wave pattern
beta brain waves
alert, attentive, focused
what lobes are associated with beta brain waves
parietal + frontal lobes
beta waves cycle
asynchronous, 14-80 cycles/sec
alpha brain wave
alert, quiet, resting, light sleep
alpha wave cycle
rhythmical, 8-13 cycle/sec
what lobe is associated with alpha waves
occipital
theta brain waves
sleep
theta wave cycle
4-7 cycle/sec
what lobe is associated with theta waves
parietal and temporal lobes
delta brain waves
deep sleep, infancy, surgical anesthesia
delta wave cycle
<3.5 cycle/sec
who are delta waves more common in
infants
what areas do alpha waves occur in
areas that have cortical connection to the thalamus
high frequency beta waves
alert wakefulness or sometimes REM sleep
REM sleep
brain awake, body asleep. dreams
slow wave sleep
healing, growing, learning, memory consolidation, restore balance, conserve energy, no dreams
characteristics of stage 1 slow wave sleep
light sleep, voltage lowering, sleep spindles of alpha waves
characteristics of stage 2 + 3 slow wave sleep
theta waves
characteristics of stage 4 slow wave sleep
deep sleep, very slow waves, high voltage
how long does REM sleep last for
5-30 minutes, every 90ish minutes
sleep theories
PUT ON EXAM SHEET
physiologic functions of sleep
maturation of neurons + NS, learning/memory facilitation, cognition, conserve metabolic energy, heal, grow, detox, restore balance to NS
