The term area 14 of Brodmann refers to a subdivision of the cerebral cortex of the guenon defined on the basis of cytoarchitecture. It differs most clearly from area 13 of Brodmann in that it lacks a distinct internal granular layer (IV). Other differences are a less distinct external granular layer (II), a widening of the relatively cell-free zone of the external pyramidal layer (III); cells in the internal pyramidal layer (V) are denser and rounded; and the cells of the multiform layer (VI) assume a more distinct tangential orientation ( Brodmann-1905 ). Brodmann's area 14 is unrelated to area 14 of Walker and area 14 (macaque), which are located in the orbital gyri. It is more equivalent to the dysgranular insula or the dysgranular insular cortex (Roberts) of later architectonic segmentations.
