paleocortex

 [pa″le-o-kor´teks]
that portion of the cerebral cortex that, with the archeocortex, develops in association with the olfactory system, and which is phylogenetically older and less stratified than the neocortex. It is composed chiefly of the piriform cortex and the parahippocampal gyrus.

pa·le·o·cor·tex

(pā'lē-ō-kōr'teks), [TA]
The phylogenetically oldest part of the cortical mantle of the cerebral hemisphere, represented by the olfactory cortex.

mesocortex

A region of the brain between the isocortex and allocortex, which contains the 1st, 5th and 6th layers and merged 2nd, 3rd and 4th layers.

pa·le·o·cor·tex

(pā'lē-ō-kōr'teks) [TA]

Segun el estudio de Barbas y Pandya (1989), el area 10 estaria dividida en 2 sectores, diferenciados por su origen filogenetico cortical: a) El area 10 orbital haria parte de la tendencia ventro-lateral que se origino en el paleocortex; y b) el area 10 de las superficies medial y lateral que formaria parte de la tendencia medio-dorsal originada en el archicortex (Barbas y Pandya, 1989).
Simulation of Paleocortex Performs Hierarchical Clustering.
Functional imaging shows the vulnerable circuitry for addiction originating in the paleocortex. Paradoxically, humankind's greatest adaptive advantage, the neocortex, responsible for the phenomenon of consciousness, is at best only minimally protective from addictive disease and may pose a hurdle for recovery.
