The neocortex has often been considered to … The neocortex has often been considered to be the evolutionarily most recent portion of the cerebral cortex, and has been shown to have undergone disproportionate enlargement with respect to the rest of the brain in insectivora through prosimians, simians, and apes to humans (Stephan et al, 1981; Rilling and Insel, 1999). It has been widely stated that expansion of neocortex underpins the higher cognitive functions in humans, though this is an area of contention and may reflect poor understanding of phylogenetic relationships and the neural substrate underlying what is deemed intelligent behavior (Stephan et al., 1981; Rilling et al., 1999). ephan et al., 1981; Rilling et al., 1999).

Part of cerebral cortex defined on the bas … Part of cerebral cortex defined on the basis of cytoarchitecture that has 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) * The largest portion of the CEREBRAL CORTEX. It is composed of NEURONS arranged in six layers. (MSH) * the newer, 6 layered portion of the cerebral cortex showing stratification and organization characteristic of the most highly evolved type of cerebral tissue. (CSP) hly evolved type of cerebral tissue. (CSP)

The term neocortex is somewhat controversi … The term neocortex is somewhat controversial (see notes below) but I am in agreement with Butler and Hodos (ISBN-13: 978-0471210054; pg 58) that even though the term is not correct in an evolutionary sense, it is the preferred term for the regions of cerebral cortex that it refers, compared to others like isocortex. So I am recommending it as a preferred label for now. ommending it as a preferred label for now.
