1

basal ganglia

smooth movement

2

cerebellum

coordinated movement

3

cerebral cortex

complex perceptual, cognitive and behavioral processes

4

hypothalamus

hunger and thirst; emotion

5

inferior and superior colliculi

sensorimotor reflexes

6

limbic system

emotion and memory: septal nuclei, amygdala, hippocampus

7

medulla oblongata

vital function (breathing, digestion)

8

reticular formation

arousal and alertness

9

thalamus

sensory relay station

10

Four lobes of cerebral cortex

frontal lobe, parietal, occipital, temporal

11

frontal lobe

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

12

parietal lobe

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

13

occipital lobe

visual processing: visual cortex (also called striate cortex)

14

temporal lobe

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

15

catecholamines

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

16

dopamine hypothesis of schizo

schizo arises from too much or an oversensitivity to dopamine

17

serotonin

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

18

GABA

gamma-aminobutyric acid; neurotransmitter stabilizes neural activity
