Term Name:	allocortex
Synonyms:	allocortex (Stephan), heterogenetic cortex, heterogenetic formations, intercalated nucleus of the medulla, nucleus intercalatus (staderini), transitional cortex
Definition:	One of two types of cerebral cortex defined on the basis of cytoarchitecture and fetal development. The other is neocortex. Allocortex does not pass through a prenatal phase of six-layered structure and has three or four layers in the mature brain ( Schiebler-1999 ). Allocortex has three subtypes: paleocortex, archicortex and periallocortex. This definition differs from that in some older sources, which excluded the olfactory bulb and the accessory olfactory bulb ( Carpenter-1983 ).
