cortex
| Term | Description |
|---|---|
| paleocortex | associated with limbic sys |
| archicortex | hippocampus |
| neocortex | 90% of all cortex, have 6 layers some time during development |
| pyramidal cells | main projection to cortex; big neuron (10 to 70/100 microns), spines on dendrites may be involved in learning |
| stellate cell | interneuron w/short axons, locally acting |
| cortical layers | alternating layers of pyramidal and granule cells |
| afferents of cortex | intra-cortex connections, subcortical areas: thalamus, locus ceruleus (other chemically coded projections) |
| efferents of cortex | subcortical via Layer V. (thalamus, spinal cord, brainstem, basal ganglia- via internal capsule); Cortical- commissural via corpus callosum/ant commissure; association fibers to same hemisphere |
| significance of cortical columns | in some areas (SS/visual cortex), all cells in a vertical column respond best to certain stimulus |
| primary sensory areas | postcentral gyrus (3,1,2), primary auditory cortex (41), primary visual cortex (17) |
| primary motor areas | precentral gyrus (4) |
| unimodal cell | respond to complex input regarding a single type of stimulus (ie.SS OR vision) |
| what are the 4 types of cortical areas? | primary sensory, primary motor, association, limbic |
| the SS cortex is composed of? | postcentral gyrus; unimodal assn cortex in sup parietal lobule (areas 5 and 7) |
| what is the visual cortex composed of? | primary visual cortex (area 17); visual assn cortex (unimodal18 and 19); other visual assn cortex (heteromodal) in temporal and parietal lobes |
| auditory cortex composed of? | (41) primary auditory cortex on transverse temporal gyrus; secondary aud cortex (42) |
| specific motor areas? | premotor area and supplementary motor area(6); primary motor area (4); frontal eye field (8) |
| language areas? | broca's (44/45) inf frontal gyrus; wernickes (22) sup temporal gyrus |
| dominant hemisphere associated with | math skills, logic |
| non-dominant hemisphere associated with | face recogntion, musical ability, spatial tasks |
| prefrontal cortex associated with | emotions, personality, intellect |
| consciousness areas | ascending reticular activating sys (reticular formation); locus ceruleous (pons); intralaminar nuclei of the thalamus |
