Flashcards in Functional Organization of Cerebral Cortex (Lecture #2) Deck (24):
1

insula

cortex inside lateral fissure

2

cerebral cortex

gray matter of cerebral hemispheres (cell bodies)

3

where do cell bodies in cerebral cortex send axons to

1. another part of the cerebral cortex
2. another part of the brain or spinal cord

4

Broadman's areas based on

gorss and microscopic appearance

5

Types of primary cortices

motor
somatosensory
visual
auditory

6

where is primary motor cortex located

precentral gyrus

7

location of primary somatosensory cortex

postcentral gyrus

8

location of primary visual cortex

surrounds calcarine fissure

9

types of unimodal association cortices

motor
somatosensory
visual
auditory

10

location of unimodal motor association area

anterior to precentral gyrus

11

function of unimodal motor association area

motor planning

12

function of unimodal somatosensory association area

assigning meaning to sensory input

13

location of unimodal somatosensory association area

parietal lobe, posterior to post-central gyrus

14

location of unimodal visual association area

occipital lobe

15

function of unimodal visual association area

depth
color
motion
shapes

16

location of unimodal auditory association area

superior frontal gyrus

17

function of unimodal auditory association area

interpretation of sounds

18

what happens if unimodal auditory association area destroyed on right side

inability to understand body language and vocal social cues (ie. sarcasm)

19

heteromodal association cortex

association cortex that receives information from 2 or more unimodal association cortices

20

parietal-temporal-occipital association cortex

complex interpretation of stimuli
-tells you what to do with stimulus

21

prefrontal association cortex location

everything anterior to frontal eye fields

22

prefrontal association cortex function

restraint, initiative, order

23

limbic cortex

-receives info from heteromodal association areas, cerebral hemispheres, and diencephalon
-involved in homeostasis, olfaction, memory, emotion
-sends info to prefrontal cortex to aid in decision making

24

general flow of info in cerebral cortex

1. primary sensory cortex
2. unimodal sensory association cortex
3. temporal-parietal-occipital association cortex
4. frontal heteromodal association cortex
5. unimodal association cortex
6. primary motor cortex
