title: Types of neurons in the nucleus ruber of the European bison. Klüver-Barrea and Golgi studies.
abstract: The studies were carried out on the mesencephalons of 4 European bison Preparations were made by means of Golgi impregnation and Klüver-Barrera method. Three types of neurons were distinguished in the red nucleus: 1. Large multipolar (perikaryons 70-105 microns) with 6-8 dendritic trunks which bifurcate twice and next give thin collaterals. 2. Small multipolar neurons (perikaryons 30-40 microns). These cells send 4-6 thick dendritic trunks. Most of the primary dendritic trunks bifurcate once. The remaining ones gives off only thin collaterals 3. Small triangular neurons (perikaryons 30-40 microns) with 3 thick dendritic trunks arising conically from perikaryons. Dendritic trunks bifurcate once near of the cell body. In all types of red nucleus neurons the axons arise directly from the surface of the perikaryons.
