Periamygdaloid cortex

Cortex periamygdaloideus

Definition

Muhammad A. Javaid

The periamygdaloid cortex is an area of cortical grey matter closely related to and covering the amygdaloid body in the anterior part of the uncus. It should be distinguished from the amygdaloid body itself, which is a deeper collection of nuclei in the uncus and medial temporal lobe region.

The periamygdaloid cortex is continuous with the grey matter of the cortical part of the amygdaloid body, providing an anatomical transition between the superficial cortex of the uncus and the deeper amygdaloid nuclear complex.

In broader anatomical terms, the periamygdaloid cortex is considered part of the olfactory-related cortex and contributes to the integration of olfactory information with limbic and emotional processing. Thus, it provides an important cortical interface between olfactory regions and the amygdaloid complex.
