The term medial mammillary nucleus refers to a well defined group of cells located ventromedially in the posterior hypothalamic region of the human, macaque, rat and mouse. Defined on the basis of Nissl stain it is the most prominent cell group in the volume bounded by the mammillary body. In the human (Saper., 2004) and the macaque (Paxinos., 2009) it is composed of two parts, the medial part of the medial mammillary nucleus and the lateral part of the medial mammillary nucleus. In the rat (Swanson., 2004) and the mouse (Hof., 2000) it is composed of two different parts: body of the medial mammillary nucleus and median part of the medial mammillary nucleus [BrainInfo: http://braininfo.rprc.washington.edu/centraldirectory.aspx?ID=414].
