area 10p - BrainInfo

area 10p (10p)

The term area 10p refers to one of three subdivisions of area 10, an area defined on the basis of multiple stains that occupies the transverse frontopolar gyri and most rostral portion of the orbital gyri at the frontal pole of the frontal lobe in the human. On the ventral surface of the lobe it is bounded, from medial to lateral, by area 11m, area 11l and area 47/12r. On the medial surface of the lobe it is bounded caudally by area 9 dorsally and by area 10r ventrally. The other subdivisions of area 10 in the human are area 10r and area 10m ( Ongur-2003 ). Its equivalent in the macaque is a combination of area 10o orbitally and the portion of area 10m at the frontal pole where the superior frontal gyrus and straight gyrus merge. The rat has a tiny area at its frontal pole that is similar in that it is granular cortex with input from the medial dorsal nucleus of the thalamus ( Krettek-1977 ), but it is not regarded as equivalent to area 10p in the human ( Wallis-2012 ) or the architectonically equivalent area in the macaque ( Preuss-1995 ).

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'.
