title: Structure and topography of the nuclei of mamillary region in the bison bonasus.
abstract: Studies were carried out on the brains of two aurochs. The paraffin cross-sections 15 microns thick were stained according to Nissl and Klüver and Barrera methods. In regio mamillaris were described two mamillary nuclei and two paramamillary nuclei. Nucleus mamillaris lateralis and nucleus supramamillaris are uniform cellular bands while the nucleus mamillaris medialis and nucleus tuberomamillaris pars posterior consist of subdivisions. Thopography of these centers in aurochs is similar to other mammals, but their shapes show the most common features with cow. Cell structure is characterized by typical species-related differences.
