The term intermediate part of the tuberal nucleus refers to the part of the tuberal nucleus located between the subventromedial part of the tuberal nucleus and the tereta hypothalamic nucleus components of the tuberal nucleus in the rat. Defined by multiple criteria, the four components line the lateral hypothalamic area at the base of the intermediate hypothalamic region. Functionally the tuberal nucleus belongs to the lateral motor zone of the subcortical motor nuclei ( Swanson-2004 ).
