Cortex Flashcards
what layer of cortex accepts most specific thalamic inputs
4
what layer accepts most nonspecific thalamic inputs
1
which is the main output layer
5
which layers specialize in cortico-cortical connections
2/3
which layer projects back to thalamus
6
what cell besides pyramid cells are excitatory
stellate cells
circuit of cortex
input to layer 4 –> layer 2/3 –> layer 5/6 –> output
primary motor cortex in pre-central gyrus
area 4
unimodal association (motor area
area 6
primary sensory cortex in post-central gyrus
3,1,2
unimodal association (somatosthesis) area in superior parietal lobule
5/7
primary visual area banking calacrine fissure
17
primary auditory area in transverse temporal gyrus of heschl
41/42
lesion of dominant side parietal association cortex
language disorders (aphasia)
lesion of non-dominant parietal association cortex
contralateral neglect syndrome - no attention to opposite side
function of parietal association cortex
attention to physical world
fuction of temporal association cortex
recognition/identification (naming things)
function of occipital association cortex
vision
function of prefrontal cortex
overall executive for behavior
responsible for “self” and “personality”
injury to temporal association cortex
decreased recognition of objects and people - agnosia
