Document Summary
Intro to cerebral cortex: cerebral cortex, neuroanatomy of the cortex. Central sulcus, lateral fissure, parieto-occipital sulcus divide brain into lobes. Don"t forget the insula and gyri: segregation of function: each lobe performs a specific function. Primary visual area is in occipital lobe (banks of calcarine fissure) Primary motor area is in frontal lobe (precentral gyrus) Primary somatosensory area is in parietal lobe (postcentral gyrus) Primary auditory area is in temporal lobe (lower bank of lateral fissure) Info from primary areas sent in two directions: memory areas in ventral temporal lobe, motor planning areas in caudal parietal lobe, definition of a cortical area. Function: this is the primary determinant of an area. Connections: define an area based on characteristic connections to other areas, e. g. connections that give an area its function.
