ALLOCORTEX

Introduction and Definition of Allocortex The allocortex represents a fundamental division of the cerebral cortex, distinguished anatomically and phylogenetically from the expansive six-layered structure known as the neocortex (or isocortex). By definition, the allocortex is cerebral cortex which possesses fewer than the six distinct cortical layers characteristic of the neocortex. This structural simplification, typically manifesting […]

PALEOCORTEX

Introduction and Definition of the Paleocortex The paleocortex, translating literally to the “old cortex,” represents a phylogenetically ancient division of the cerebral cortex, distinguished fundamentally by its simplified cytoarchitecture compared to the expansive six-layered neocortex. It is formally classified as a type of allocortex, a term encompassing cortical regions that possess fewer than the standard […]
