Topography and microscopical configuration of the corpus striatum of the dog

The basal ganglia are very similarly disposed in superior animal, but their way of grouping is different in human species and domestic mammals. We have studied them in the dog, except for the Nucleus accumbens, from macroscopic and microscopic points of view, with the help of 25 and 50 pm thick transverse serial sections, stained by Nissl's technique. Each of these nuclei presents its own characteristics, as well topographically and extended as of shape, size and neuron density.
