Summary and Conclusions
Brain stems of 75 newborn kittens and 70 newborn rats and mice were treated according to three modifications of the Golgi method (Golgi rapid method, Golgi Cox method, and Golgi Kopsch method). As material of reference were employed sections of brain stems from newborn kittens, rats, and mice, stained with thionine or silver according to methods described by Nissl and Bodian, respectively.
The cyto- and fibroarchitectures of the vestibular nuclear complex are described. The general pattern of nuclei, cell groups, and subregions of the main nuclei as previously described by Brodal and Powtreiano (1957 a) was confirmed in the present material.
The nerve cells are grouped according to size in small, middle-sized, large, and giant cells. The latter cells are present mainly in the lateral vestibular nucleus of Deiters.
In the four main vestibular nuclei (the superior, the lateral, the medial, and the descending) the nerve cells are characterized by long, radiating dendrites with rather few branches. The giant cells have more richly branched dendrites than those of the other groups.
