An area of cerebral cortex defined on the basis of cytoarchitecture that have six layers. Starting from the cortical surface the layers are: molecular layer (I), external granular layer (II), external pyramidal layer (III), internal granular layer (IV), internal pyramidal layer (V), and multiform layer (VI). Neocortex is most prominent in the frontal lobe, the parietal lobe, the temporal lobe and the occipital lobe, less so in the cingulate gyrus, the parahippocampal gyrus and the insula. It is composed of two subdivisions: true isocortex and proisocortex (Carpenter-83)(NN). [ BIRNLEX:2547 OldNeuroNames:754 ]
Synonyms: homotypical cortex neocortex (isocortex) cerebral neocortex isocortex (sensu lato) neopallial cortex homogenetic cortex neopallium
