Abstract
A review of the literature pertinent to the nuclei of the cervoid mesencephalon was made, and species variations were compared with the observations made in the deer. A total of eight deer brains were sectioned, six in the transverse plane and one each in the horizontal and sagittal planes. The cytoarchitecture of the nontectal mesencephalic nuclei of the deer, Odocoileus virginianus, is described. The cell bodies of the deer mesencephalon can be grouped into nuclei that have their counterparts in the brain stem of other wild and domestic ungulates and carnivores. Although the brain stem of the deer resembles the same region in other mammals, differences are observed. These include variations in the size and topography of certain nuclei, differences in relative proportions of cell types in some nuclei, and the absence of a few nuclei in the deer.
