medial amygdalar nucleus
Acronym: MeA
The term medial amygdalar nucleus refers to a composite structure of the amygdala defined on the basis of Nissl stain. In the human ( Mai-1997 ) and the macaque ( Amaral-1992 ) it consists of two parts, the anterior part of the medial amygdalar nucleus and the posterior part of the medial amygdalar nucleus.
     In the rat ( Swanson-2004 ) and the mouse ( Hof-2000 ) it is subdivided into five parts: the anterodorsal part of the medial amygdalar nucleus, the anteroventral part of the medial amygdalar nucleus, the posterodorsal part of the medial amygdalar nucleus, the posteroventral part of the medial amygdalar nucleus and the nucleus of the accessory olfactory tract.
     Classically the medial amygdalar nucleus is categorized as part of the corticomedial nuclear group ( Carpenter-1983 ). In the functional nervous system it is classified as part of the extended striatum ( Swanson-2004 ).
