ch 1 - Biology and Behavior

Question 1

basal ganglia

Answer 1

smooth movement

Question 2

cerebellum

Answer 2

coordinated movement

Question 3

cerebral cortex

Answer 3

complex perceptual, cognitive and behavioral processes

Question 4

hypothalamus

Answer 4

hunger and thirst; emotion

Question 5

inferior and superior colliculi

Answer 5

sensorimotor reflexes

Question 6

limbic system

Answer 6

emotion and memory: septal nuclei, amygdala, hippocampus

Question 7

medulla oblongata

Answer 7

vital function (breathing, digestion)

Question 8

reticular formation

Answer 8

arousal and alertness

Question 9

thalamus

Answer 9

sensory relay station

Question 10

Four lobes of cerebral cortex

Answer 10

frontal lobe, parietal, occipital, temporal

Question 11

frontal lobe

Answer 11

executive function, impulse control, long-term planning (prefontal), motor function (primary motor cortex), speech production (Broca’s)

Question 12

parietal lobe

Answer 12

sensation of touch, pressure, temp, and pain (somatosensory cortex); spatial processing, orientation, and manipulation

Question 13

occipital lobe

Answer 13

visual processing: visual cortex (also called striate cortex)

Question 14

temporal lobe

Answer 14

sound processing (auditory cortex), speech perception (Wernicke’s area), memory, and emotion (limbic system)

Question 15

catecholamines

Answer 15

norepi (low = depression, high = anxiety/mania), epi (alertness), and dopamine (movement and posture (basal ganglia))

Question 16

dopamine hypothesis of schizo

Answer 16

schizo arises from too much or an oversensitivity to dopamine

Question 17

serotonin

Answer 17

monoamine and biogenic amine neurotransmitter - too little = depression; too much = mania; maybe regulates eating, mood, sleeping, dreaming

Question 18

GABA

Answer 18

gamma-aminobutyric acid; neurotransmitter stabilizes neural activity
