area 8Ad - BrainInfo

area 8Ad (8Ad)

The term area 8Ad refers to the more dorsal of two components of area 8A. In the human it is located posteriorly in the middle frontal gyrus. Defined on the basis of multiple stains, it is bounded rostrally by area 9/46d, caudally by area 6; dorsally by area 8B and ventrally by the other component of area 8A, area 8Av. Its equivalent in the macaque is similarly located with its upper boundary at the superior limb of the arcuate sulcus and its lower boundary partially defined by the principal sulcus ( Petrides-2012 ). As granular prefrontal cortex, it has no equivalent in the rat ( Zilles-2012 ).

Also known as: area 8Ad, area 8Ad of cortex, anterodorsal part

Models Where It Appears

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'.
