Topography and cytoarchitectonics of the nuclei of the posterior part of hypothalamus in insectivora. Part II. Regio premamillaris.

Cross-section paraffin scraps were stained with the methods of Nissl and Klüver-Barrera. A description was given of the topography, shape and cell structure of the nuclei in the regio premamillaris in 3 insectivorous mammals: hedgehog, mole and common shrew. Attention was also given to the nervous centres located in the mentioned region but extending over the whole hypothalamus (nucleus perifornicalis, area hypothalamica lateralis). No differences were observed as to the location of the centres under study, but their cytoarchitectonics differed depending on the species.
