lateral part of the medial mammillary nucleus (MML)

The term lateral part of the medial mammillary nucleus refers to the more lateral of two parts of the medial mammillary nucleus in the human ( Saper-2004 ), the macaque ( Paxinos-2009a ), the rat ( Paxinos-2009b ), and the mouse ( Franklin-2008 ). In the human it is considerably smaller than the medial part of the medial mammillary nucleus from which it is separated by fibers of the fornix ( Saper-2004 ). In the macaque, rat, and mouse the medial and lateral parts are more equal in size. Some authors do not divide the medial mammillary nucleus of the rat ( Swanson-2004 ) and mouse ( Hof-2000 ) into medial and lateral parts. The combination is equivalent to the body of the medial mammillary nucleus in their parcellation. Functionally the medial mammillary nucleus is part of the behavior control column of the brainstem motor system ( Swanson-2004 ).

Also known as: lateral part of the medial mammillary nucleus, Nucleus corporis mamillaris medialis, pars lateralis, lateral subdivision of medial mammillary nucleus, medial mammillary nucleus, lateral part, Nucleus intermedius corpus mamillaris, intermediate mammillary nucleus, intercalated mammillary nucleus, lateral mammillary nucleus (Gagel), Nucleus intercalatus corporis mammillaris

Models Where It Appears
Structural CNS Model - Macaque

Brain structures of the macaque are illustrated in BrainInfo’s NeuroMaps macaque brain atlas. Structures are grouped by proximity in a hierarchy corresponding to the central nervous system hierarchy of NeuroNames ( Bowden-1995 Martin-2000 ). Structures in the NeuroMaps atlas are based on the segmentation of an MRI of the brain of a 3-year old male rhesus macaque (Macaca mulatta). The atlas is most useful for targeting structures for implantating electrodes and chemtrodes. Updated 29 Oct 2025.
