The term anterior part of the dorsomedial hypothalamic nucleus refers to one of three parts of the dorsomedial nucleus of the hypothalamus in the rat as subdivided on the basis of multiple criteria. The others are the posterior part of the dorsomedial hypothalamic nucleus and the ventral part of the dorsomedial hypothalamic nucleus. Functionally the dorsomedial nucleus is part of the hypothalamic periventricular region of the subcortical motor system ( Swanson-2004 ).
