MCAT BEHAVIORAL SCIENCES Flashcards
ORGANIZATION of the BRAIN:
hindbrain
cerebellum
medulla ob
retic formation
ORGANIZATION of the BRAIN:
midbrain
inf and sup colliculi
ORGANIZATION of the BRAIN:
forebrain
thalamus, hypothalamus, basal gang, limbic sys, and cerebral cortex
PARTS of the FOREBRAIN:
thalamus
sensory infor (hunger, thirst)
PARTS of the FOREBRAIN:
hypothalamus
drives behavior (fight, feed, flee, fuck)
PARTS of the FOREBRAIN:
basal ganglia
smooths movements and posture
PARTS of the FOREBRAIN:
limbic system
emotion and memory
- septal nuclei = pleasure seeking
- amygdala = fear/anger
- hypocampus = memory
- fornix = communication w/in
PARTS of the FOREBRAIN:
cerebral cortex
4 lobes
- frontal = executive fcn, long term planning, impulse, motor, speech
- parietal = touch, press, temp and pain (sensory)
- occipital = visual/color
- temporal = sound, speech
acetylcholine
voluntary control (somatic), parasymp
dopamine
smooth muscle, posture, euphoria
GABA
brain stabalization
sensation/sensory receptors
physical stimuli conversion and trigger electrical signals
Weber’s Law
just noticeable difference (proportional)
cochlea
detects sound
utricle and saccule
linear accel
semicircular canals
rotational accel
bottom up
(data)
parallel processing, slow
top-down
recognition, no detail
LEARNING AND MEMORY:
classical conditioning
unconditioned stimulus (food) and conditioned stimulus (bell)
LEARNING AND MEMORY:
operant conditioning
reinforcement and punish
add something to make it continue
pos reinforce
remove something and it continues
neg reinforce (anti-acid an escape from sumn)
add something to make it stop
pos punish (jail)
remove something and it stops
neg punish
COGNITION, CONSCIOUSNESS, AND LANGUAGE:
consciousness
stage -awake = beta and alpha -1 = theta, light sleep -2 = theta, sleep spindles/ k complex -3/4 =delta, deep sleep, slow waves REM = beta
COGNITION, CONSCIOUSNESS, AND LANGUAGE:
depressents
alcohol, barbs, benzos (relax)
COGNITION, CONSCIOUSNESS, AND LANGUAGE:
stimulants
ampheta, coke, Ex (incr arousal)
COGNITION, CONSCIOUSNESS, AND LANGUAGE:
opiates/opioids
heroin, morph, opium (descr rxn)
MEMORY:
explicit
conscious
MEMORY:
implicit
unconscious (riding a bike)
MEMORY:
declaritive
from explicit; facts and event
MEMORY:
procedural
from implicit; skills and tasks
MEMORY:
episodic
events and experieinces
MEMORY:
semantic
facts and concepts; general world knowledge
