Functional Organization of Cerebral Cortex (Lecture #2) Flashcards
insula
cortex inside lateral fissure
cerebral cortex
gray matter of cerebral hemispheres (cell bodies)
where do cell bodies in cerebral cortex send axons to
- another part of the cerebral cortex
2. another part of the brain or spinal cord
Broadman’s areas based on
gorss and microscopic appearance
Types of primary cortices
motor
somatosensory
visual
auditory
where is primary motor cortex located
precentral gyrus
location of primary somatosensory cortex
postcentral gyrus
location of primary visual cortex
surrounds calcarine fissure
types of unimodal association cortices
motor
somatosensory
visual
auditory
location of unimodal motor association area
anterior to precentral gyrus
function of unimodal motor association area
motor planning
function of unimodal somatosensory association area
assigning meaning to sensory input
location of unimodal somatosensory association area
parietal lobe, posterior to post-central gyrus
location of unimodal visual association area
occipital lobe
function of unimodal visual association area
depth
color
motion
shapes
location of unimodal auditory association area
superior frontal gyrus
function of unimodal auditory association area
interpretation of sounds
what happens if unimodal auditory association area destroyed on right side
inability to understand body language and vocal social cues (ie. sarcasm)
heteromodal association cortex
association cortex that receives information from 2 or more unimodal association cortices
parietal-temporal-occipital association cortex
complex interpretation of stimuli
-tells you what to do with stimulus
prefrontal association cortex location
everything anterior to frontal eye fields
prefrontal association cortex function
restraint, initiative, order
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
general flow of info in cerebral cortex
- primary sensory cortex
- unimodal sensory association cortex
- temporal-parietal-occipital association cortex
- frontal heteromodal association cortex
- unimodal association cortex
- primary motor cortex
