Question 1

thalamic reticular necleus (TRN) (what is it?)

Answer 1

region in thalamus with entirely inhibitory cells

Question 2

how many cortical layers

Answer 2

6

Question 2

thalamic reticular necleus (TRN) (what does it do)

Answer 2

recovers input form cortex and other regions, the cells inhibit the activation of primary an secondary thalamic regions

Question 3

cortical columns

Answer 3

unit of neurons in a column that respond to similar sensory features

Question 3

flow form thalamus to cortical layers

Answer 3

thalamus -> layer 4 -> layer 2/3 -> layer 5 -> layer 6

Question 4

frontal lobe

Answer 4

memory, planning, action planning/inhibition

Question 4

somatosensory cortex

Answer 4

in parietal lobe, different regions denoted to different body parts

Question 4

corticospinal tract

Answer 4

controls muscle required for prescies moment

Question 4

occipital lobe

Answer 4

visual cortex and sub regions

Question 4

temporal lobe

Answer 4

auditory cortex and subregions

Question 5

parietal lobe

Answer 5

sensory

Question 5

commissure

Answer 5

crossing axons

Question 6

primary motor cortex

Answer 6

located in the frontal lobe

Question 7

where does info cross

Answer 7

medulla

Question 8

retina pathway

Answer 8

lateral geniculate nuclues (in thalamus) -> primary visual cortex (V1) then sends to higher visual pathways (V2-V4)

Question 9

ventral visual stream (pathway)

Answer 9

visual cortex to inferior temporal cortex

Question 10

ventral visual stream (what it does)

Answer 10

determines what an object is, and where it is located in visual space

Question 11

dorsal visual system (pathway)

Answer 11

visual cortex to posterior parietal cortex

Question 12

dorsal visual system (what it does)

Answer 12

determines where an object is located and motion of object

Question 13

intertemporal cortex

Answer 13

face patch region

Question 14

FFA fusiform face area

Answer 14

indentification of a person

Question 15

OF A occipital face area

Answer 15

perception of specific facial features

Question 16

mirror neurons

Answer 16

cells that increase activity durning the execution of a task AND the observation of a task
