orbital frontal cortex

orbital frontal cortex (FRCor)

The term orbital frontal cortex refers to a segmentation of the orbital gyri on the basis of multiple stains for internal structure. One of two subdivisions of the orbitomedial prefrontal cortex, it is composed of six areas. In the human they are: area 10, area 11, area 47, area 13, area 14, and the agranular orbitofrontal cortex ( Ongur-2003 ). In the macaque area 47 was long named 'area 12' ( Carmichael-1994 ). The other division of the orbitomedial prefrontal cortex is the medial prefrontal cortex of Ongur. In both the human and the macaque the orbital prefrontal cortex is largely granular cortex, which has no equivalent in the rat ( Wise-2008 ).. Only the most caudal strip of the orbital prefrontal cortex is agranular. The equivalent of that narrow area may be found in the orbital areas (rodent) and the agranular insular cortex of the rodent ( Preuss-1995; Wallis-2012 ).

Also known as: orbital frontal cortex, orbital prefrontal cortex of Ongur

Models Where It Appears

orbitomedial prefrontal cortex hierarchy

refers to the organization of substructures of the orbitomedial prefrontal cortex of the human as described in Ongur-2003. The organization is the same in the macaque, except for a few minor differences in internal structure and names based on topology ( Carmichael-1994 ).

Topographic Model of Human Cerebral Cortex

The topographic model of human cerebral cortex is a closed partitive hierarchical model of cerebral cortical structure in the human. The cerebral cortex is segmented on the basis of internal structure, connectivity, and/or functions of cortical areas. It is designed to update the comprehensive early twentieth century parcellations of Brodmann and of von Economo and Koskinas and their successors. A work in progress, it integrates the most authoritative, comprehensive, and recent parcellations and nomenclatures from peer-reviewed publications and neuroanatomical texts. For an equivalent model in the rodent, Search BrainInfo for ' Functional CNS Model - Rat '. This segmentation of the human cerebral cortex, based on a combination of internal structure, connectivity, and function, complements the classical segmentation of the cerebral cortex into lobes, lobules, and gyri based on sulcal patterns: For the classical segmentation, see ' cerebral cortex ' and click 'Locus in Brain Hierarchy'.
