area 12 of Brodmann (guenon)

area 12 of Brodmann (guenon) (12)

The term area 12 of Brodmann (guenon) refers to a subdivision of the cerebral cortex of the guenon defined on the basis of cytoarchitecture. It occupies the most rostral portion of the frontal lobe. Brodmann-1909 did not regard it as homologous, either topographically or cytoarchitecturally, to area 12 of Brodmann (human). More recent authors consider it the equivalent of area 12 and area 47 of the human ( Carmichael-1994; Ongur-2003 ). Distinctive features according to Brodmann-1905: a quite distinct internal granular layer (IV) separates slender pyramidal cells of the external pyramidal layer (III) and the internal pyramidal layer (V); the multiform layer (VI) is expanded, contains widely dispersed spindle cells and merges gradually with the underlying cortical white matter; all cells, including the pyramidal cells of the external and internal pyramidal layer are inordinately small; the internal pyramidal layer (V) also contains spindle cells in groups of two to five located close to its border with the internal granular layer (IV).

Also known as: frontopolar area, area 12 of Brodmann (guenon), Brodmann's area 12

NeuroNames is used as a term's source if no published source of the term has been found. In most cases, the term is an English translation of a commonly used Latin term. In some cases it is a Latin translation of an English term for which no published Latin equivalent has been found. Latin roots of words not found in the neuroanatomical literature are derived from Cassell's Latin Dictionary (Simpson-59).
