Answer 1

FTOP: frontal temporal occipital parietal

Question 2

central sulcus

Answer 2

between frontal and parietal lobes

Question 3

sylvian fissure (lateral sulcus)

Answer 3

between frontal and temporal lobes

Question 4

parieto-occipital sulcus

Answer 4

between parietal and occipital lobes

Question 5

sulcus

Answer 5

valley of the brain folds

Question 6

gyrus

Answer 6

hill of the brain folds

Question 7

primary motor cortex lcation

Answer 7

immediately rostral of the central sulcus

Question 8

primary sensory cortex location

Answer 8

immediately caudal of the central sulcus

Question 9

entorhinal location

Answer 9

bottom inside of the brain

Question 10

cingulate gyrus location

Answer 10

rostral anterior frontal

Question 11

orbito frontal gyrus location

Answer 11

front bottom of the brain

Question 12

visual network location and functions

Answer 12

back of occipital lobe
processes visual info
inferior temporal lobe helps determine what an object is

Question 13

somatomotor network

Answer 13

primary motor and primary sensory cortices work together

Question 14

dorsal attention network

Answer 14

next to occipital and around top of somatomotor
determine whether an object is moving, its location, and move the eyes to the object

Question 15

ventral attention/salience network

Answer 15

either side of somatomotor network
detect and direct attention to unexpected stimuli

Question 16

limbic network

Answer 16

orbitofrontal cortex regulates emotion
entorhinal cortex regulates memory

Question 17

control network

Answer 17

complex cognition, decisions, problem solving, holding info

Question 18

default mode network

Answer 18

suppressed while doing anything
responsible for internally directed thought

Question 19

commissural fibers

Answer 19

communication between hemispheres
ex corpus callosum

Question 20

anterior commissure

Answer 20

olfaction

Question 21

posterior commissure

Answer 21

pupillary light reflex

Question 22

projection fibers

Answer 22

communication with brain stem and body
ex. corticospinal tract

Question 23

association fibers

Answer 23

communication within a hemisphere

Question 24

u fibers

Answer 24

short range association fiber

Question 25

long fiber

Answer 25

long range association fiber
ex. arcuate fasciculus: connects language areas

Question 26

grey matter development trajectory

Answer 26

increases rapidly, peaks age 6, declines slowly

Question 27

white matter development trajectory

Answer 27

increases until age 20, then declines slowly

Question 28

cortical thickness development trajectory

Answer 28

increases rapidly, peaks at age 1, declines super slowly
