In all mammalian species thus far studied, it is well established that the large, prominent, mammillothalamic tract (MTT) of the mammalian forebrain, with nearly as many fibers as the optic nerve, connects the phylogenetically primitive mammillary bodies to the uniquely mammalian anterior thalamic nuclei (Fry, et al. , 1963; Fry et al . , 1964; Guillery, 1961). This tract is thus interposed between hippocampus, many of whose projections terminate in the mammillary bodies, and the cingulate cortex, which receives fibers from the anterior thalamus . In contrast to the morphological prominence of the mammillothalamic system, which is seen upon even gross examination of the mammalian brain, knowledge of the function of this system is relatively limited.
