cortical amygdalar nucleus
Acronym: COA
The term cortical amygdalar nucleus refers to the greater part of the amygdala on the medial surface of the anterior parahippocampal gyrus (PHGa) in the human and macaque ( Amaral-1992 ). In the rat ( Swanson-2004 ) and mouse ( AMBA-2024 ) it is located on the ventromedial surface of the cerebral hemisphere. Defined topologically and histologically, It is surrounded in the human and macaque by the piriform cortex (PIR) ventrally, the entorhinal area (ENT) laterally, the medial amygdalar nucleus (MEA) dorsally and the hippocampal complex (HPC) caudally.
      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 ).
      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 ),
