isocortex

Neocortex or Neopallium, which corresponds to the isocortex.

In mammals, the pallium evolves into a complex six-layered structure called neocortex or isocortex.

The paralimbic cortex, also referred to as the mesocortex, is interposed between the isocortex and the allocortex.

The human pallium (cloak in Latin) envelops most of the telencephalon, due to extensive surface expansion of the isocortex.

Examples of heterotypic isocortex are agranular area 4 of Brodmann and striate area 17 of Brodmann.

Children with this disorder are born without a forebrain, the largest part of the brain consisting mainly of the telencephalon (which include the isocortex, which is responsible for higher level cognition, i.e., thinking).

With Gerhardt von Bonin (1890-1979), Bailey authored two works, "The Neocortex of Macaca Mulatta" and "The Isocortex of Man", which provided an accurate description concerning the cytoarchitecture of the cerebral cortex.

In mammals, the cortical part of the pallium registers a definite evolutionary step-up in complexity, forming the cerebral cortex, most of which consists of a progressively expanded six-layered portion isocortex, with simpler three-layered cortical regions allocortex at the margins.

Others postulate it directly transforms into the six-layered isocortex (neocortex) characteristic of mammals, and still others suppose that medial and lateral parts of the dorsal pallium contribute (perhaps with some contributions from the lateral pallium) to the alternative allocortical and isocortical fates.

The phylogenetically most recent part of the cerebral cortex, the neocortex (also called isocortex), is differentiated into six horizontal layers; the more ancient part of the cerebral cortex, the hippocampus (also called archicortex), has at most three cellular layers, and is divided into subfields.
