area 47/12s - BrainInfo

area 47/12s (47/12s)

The term area 47/12s refers to one of four subdivisions of area 47 in the orbital gyri of the human cerebral cortex. Composed of granular cortex, it is defined on the basis of multiple stains for internal structure. It is located adjacent to the agranular orbitofrontal cortex in the posterior part of the lateral orbital gyrus and in the dorsal bank of the anterior horizontal limb of the lateral fissure. It is bounded medially by area 47/12m. The other subdivisions are area 47/12l and area 47/12r. For the relations of this segmentation and terminology to others, see Ongur-2003. It may be equivalent to area 47s in the human ( Glasser-2016 ). The equivalent area in the macaque is area 12o (macaque) ( Ongur-2003 ). As granular prefrontal cortex, it has no equivalent in the rat ( Wallis-2012 ).

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'.
