corticomedial

The reduction of size occurred in a structure known as the corticomedial nuclear group which the CE nucleus belongs to.

Serving as a major output pathway of the amygdala, the stria terminalis runs from its corticomedial division to the ventral medial nucleus of the hypothalamus.

The pheromonal information travels via nerves to the accessory olfactory bulb, and then to the corticomedial amygdala, accessory olfactory tract, and stria terminalis.

It includes the central amygdalar nucleus and a portion of the corticomedial nuclear group of the amygdala, the portion of substantia innominata ventral to the globus pallidus and putamen, the medial portion of nucleus accumbens, and the nucleus of stria terminalis.
