The mammillothalamic tract (also mammillary fasciculus,[1]mammillothalamic fasciculus, thalamomammillary fasciculus, bundle of Vicq d'Azyr) is an efferent pathway of the mammillary body which projects to the anterior nuclei of thalamus. It consists of heavily myelinated fibres.[1] It is part of a brain circuit involved in spatial memory.[2][3]
It arises from (the medial and lateral nuclei of) the mammillary body and from fibers that are directly continued from the fornix.[2][3] It connects the mammillary body to the dorsal tegmental nuclei, the ventral tegmental nuclei, and the anterior thalamic nuclei.[2][3][4]
