area 47 - BrainInfo

area 47 (47)

The term area 47 refers to the lateral portion of the orbital gyri segmented on the basis of multiple stains for internal structure in the human ( Ongur-2003 ). Composed of granular cortex, it is located between the agranular orbitofrontal cortex posteriorly, area 11 anteriorly, and area 13 medially. It extends across the ventral margin onto the lateral surface of the frontal lobe, where it is bounded superiorly by area 45 caudally and area 10 rostrally. It is one of five subdivisions of the orbital prefrontal cortex; the others, in addition to the three mentioned, are area 14 and the orbital portion of area 10p. It is subdivided into four areas: area 47r, area 47m, area 47l, and area 47s. The equivalent area in the macaque is often referred to as area 12 ( Ongur-2003 ) or area 47/12 ( Petrides-2012 ). As granular prefrontal cortex, it has no equivalent in the rat ( Wallis-2012; Ongur-2003 ).

Also known as: lateral orbital cortex, area 12, area 47, area 47/12, area 12 of Carmichael, area 12 (macaque), area old 12

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'.
