biopsychosocial systems

Answer 1

study the links between biology and behavior.

Question 2

Gall’s Bumps:

Answer 2

DONT tell us about how our brain areas work;

DO tell us the brain separated into different operating functions

Question 3

action potential

Answer 3

stimulation -> electric charge -> depolarization -> transmission -> recharge/refactory

Question 4

Answer 4

types of imaging

Question 5

brain structure (bottom -> top):

Answer 5

Cortex areas:
Frontal: everything else
*Motor, Somatosensory
Parital: sensory(touch)
Temporal: auditory
Occipital: visual
Limbic system:
hippocampus: conscious mems
amyglada: fear/agression

Cerebellum (judgment, processing, voluntary movement/life sustaining, etc.)=Brainstem:
thalamus (comm.)
reticular formation (road/channel)

            pons (coordination)
            medulla (breathing/heartbeat)

Question 6

neural plasticity

Answer 6

brain’s ability to repair itself to function after damage to an area via neurogenesis

diminishes abilities with age increase

Question 7

split brain vs intact brain

Answer 7

cuts tissues making up corpus callosum
