area 24o - BrainInfo

area 24o (24o)

The term area 24o refers to the portion of area 24 in anterior cingulate cortex of the human, macaque, rat and mouse. Located in the part of the anterior cingulate gyrus adjacent to the genu of the corpus callosum, it consists of three parts: area 24a, area 24b and area 24c. The rat and mouse lack an area 24c. While original sources name it simply '24' ( Vogt-2012; Ongur-2003 ), it is named '24o' in NeuroNames to eliminate ambiguity with the larger area 24 as defined in Brodmann-1909, i.e., as the combination of all subareas of area 24 including those in both anterior cingulate cortex and midcingulate cortex.

Also known as: area 24x, area 24o

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'.
