25 Cards in this Set
- Front
- Back
|
brainstem |
hindbrain & midbrain, most primitive region of the brain |
|
|
limbic system |
emotion & memory; aggression, fear, pleasure, & pain; septum, amygdala, and hippocampus |
|
|
cerebral cortex |
outer covering of cerebral hemispheres; language and problem solving; complex perceptual, cognitive, and behavioral processes |
|
|
medulla oblongata |
lower brain structure responsible for breathing, heart beat, and blood pressure |
|
|
pons |
above medulla, contains sensory and motor tracts between cortex and medulla |
|
|
cerebellum |
mushrooming out of pons; maintains posture & balance, coordinates body movements |
|
|
reticular formation |
hindbrain to midbrain; network of nerve fibers; arousal, alertness, attention |
|
|
superior colliculus |
receives visual sensory input |
|
|
inferior colliculus |
receives auditory sensory input |
|
|
thalamus |
important relay of sensory information (all except smell); sorts and sends to appropriate areas of cerebral cortex |
|
|
basal ganglia |
movement |
|
|
hypothalamus |
hunger and thirst; emotion "fight or flight" |
|
|
lateral hypothalamus |
hunger center; lesions cause aphagia |
|
|
ventromedial hypothalamus |
satiety center; lesions cause hyperphagia |
|
|
anterior hypothalamus |
electrical stimulation causes aggressive sexual behavior |
|
|
septum |
pleasure center of brain; damage can cause septal rage |
|
|
amygdala |
damage reduces aggression & fear; linked to defense & aggresion; Kluver-Bucy syndrome |
|
|
hippocampus |
learning and memory; lesions produce anterograde amnesia |
|
|
cerebral cortex |
comprised of four lobes - frontal, parietal, occipital, and temporal |
|
|
frontal lobe |
contains prefrontal lobes and motor cortex, also Broca's area (produce speech) |
|
|
prefrontal lobes |
association area - combines input from diverse brain regions |
|
|
projection areas |
receive incoming sensory info or send out motor-impulse commands (e.g. visual cortex and motor cortex) |
|
|
parietal lobe |
rear of frontal lobe; contains somatosensory cortex, which sends signals to motor cortex (sensory motor cortex) |
|
|
occipital lobes |
rear of brain, contain visual cortex (striate cortex) |
|
|
temporal lobes |
auditory cortex & Wernike's area (language comprehension) |
