area p24d - BrainInfo

area p24d (p24d)

The term area p24d refers to an area at the caudal extreme of the anterior cingulate gyrus that is defined on the basis of internal structure. It is the part of the posterior midcingulate cortex located caudal to area a24c' and rostral to area 23c of Vogt in the human and the macaque ( Vogt-2012 ). In the human it is divided into to subareas: area p24dv in the ventral bank of the cingulate sulcus and area p24dd in the dorsal bank. In the macaque it is distinguishable from area a24c' by: 1) larger cells in the internal pyramidal layer (V), 2) cells of medium size in the lower part of the external pyramidal layer (III), 3) a more prominent columnar pattern, and 4) greater myelinization with a horizontal plexus ( Matelli-1991 ).

Also known as: area 24d, gigantopyramidal field, area p24d

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'.
