anterior cortical amygdalar nucleus
Acronym: ACo
The term anterior cortical amygdalar nucleus refers to one of two subdivisions of the cortical amygdalar nucleus as identified by multiple criteria. It is located rostral to the other subdivision, the posterior cortical amygdalar nucleus. In the human ( Mai-1997 ) and the macaque ( Paxinos-2009a ) its surface is the posterior part of the periamygdalar area of the parahippocampal gyrus on the medial surface of the temporal lobe; internally it extends ventromedially from the medial amygdalar nucleus. In the rat ( Swanson-2004 ) and the mouse ( Hof-2000 ) it is located on the ventromedial surface of the cerebral hemisphere and extends laterally from the medial amygdalar nucleus. The nomenclature, boundaries and internal subdivisions of the structure vary greatly from author to author depending on species and method of identification.
