area 8B - BrainInfo

area 8B (8B)

The term area 8B refers to the more dorsal and medial of two components of area 8 in the human. It is located posteriorly in the superior frontal gyrus and the middle frontal gyrus. Defined on the basis of multiple stains, it is bounded rostrally by area 9 and caudally by area 6; on the medial surface of the superior frontal gyrus it is bounded ventrally by area 24 and area 32ac; on the dorsal surface it is bounded laterally by the other component of area 8, area 8A. Its equivalent in the macaque is similarly located, with the superior limb of the arcuate sulcus representing the boundary between it and area 8A ( Petrides-2012 ). Functionally it is referred to as the Premotor Ear-Eye Field, (PEEF) ( Lanzilotto-2015 ). As granular prefrontal cortex, it has no equivalent in the rat ( Zilles-2012 ).

Also known as: area 8B, area 8 of cortex, Premotor Ear-Eye Field

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'.
