Biological Bases of Behavior V: Special Topics Flashcards
tonic vs clonic stage
continuous tension/contraction, involuntary alternating contractions/relaxation
waves in stage 1 sleep
theta
muscle tone in REM vs. nonREM
maintain tone in REM, very relaxed during REM
waves in stage 2 sleep
spindles
used for visualizing brain structure with radio waves
MRI
when a person closes their eyes and relaxes, ________ waves dominate
alpha
which stage of sleep involves REM?
4
health belief model says
people who think they can control their health engage in health behaviors and decrease harmful behaviors
electrical abnormalities in focal area of brain, consciousness retained
simple partial seizures
sleeper is hard to awaken during ______ sleep
stages 3 and 4
used for demonstrating brain activity or funcitoning
PET scan
waves in stage 3 sleep
delta
used for visualizing brain structure with x-ray
CAT scan
waves in stage 4 sleep
theta
initially localized motor seizure, with a spread of abnormal activity to adjacent brain areas
jacksonian
seizures that last from 1-30 seconds, with blinking or eye rolling, and slight muscle movements
petit mal
when a person is alert and attentive, _______ waves dominate
beta
gate control theory
sensations of pain aren’t directly related to activation of pain receptors, but are mediated by neural gates in the spinal cord. Why rubbing on a hurt area can relieve pain.
REM proportion over the lifespan
decreases
3 stages of General Adaptation Syndrome
alarm, resistance, exhaustion
preceded by an aura, purposeless behavior, lip smacking, unintelligible speech, with consciousness impaired
complex partial seizure
which stage of sleep occupies the greatest amount of time?
2
