cortical amygdalar nucleus
Acronym: COA
The term cortical amygdalar nucleus refers to the greater part of the amygdala facing the medial surface of the anterior parahippocampal gyrus (PHGa) in the human and macaque ( Amaral-1992 ) and the ventromedial surface of the cerebral hemisphere in the rat ( Swanson-2004 ) and mouse ( AMBA-2024 ). Defined on the basis of histology, it is subdivided into an anterior cortical amygdalar nucleus and a posterior cortical amygdalar nucleus. In the human and the macaque the cortical surface is referred to as the periamygdalar area ( Carpenter-1983 ),
      In the human and the macaque the COA is located between the medial amygdalar nucleus (MEA) dorsally and the periamygdalar cortex (PAC) ventrally. In the rat ( Swanson- 2004 ) and mouse ( AMBA-2024 ) its neighbors dorsally are the are the MEA, nucleus of the olfactory tract or the amygdalohippocampal area; ventrolaterally it is bounded by the piriform amygdalar area, the postpiriform transition area and piriform cortex ( Swanson-2004 ).
