Brodmann area 14

Brodmann's Area 14 is one of Brodmann's subdivisions of the cerebral cortex in the brain. It was defined by Brodmann in the guenon monkey. No equivalent structure exists in humans.

Anatomy
Area 14 is located in the insular cortex and is not normally visible on the brain's surface. It is hidden at the bottom of the Sylvian fissure between the frontal and parietal lobes.

Brodmann's areas were defined based on cytoarchitecture rather than function. Area 14 differs most clearly from Brodmann area 13-1905 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

Function
Area 14 is believed to serve as association cortex for the visceral senses and olfaction along with Area 13. They also serve to aggregate autonomic information.
