title: Topography and cytoarchitectonics of small-cell nuclei of the tuber cinereum in Insectivora.
abstract: Results are presented of the comparative studies on location and cytoarchitectonics of the nuclei in tuber cinereum of hypothalamus in 3 insectivorous mammals: hedgehog, mole and common shrew. Paraffin scraps were stained with the methods of Nissl and Klüver-Barrera. It was found that this part of the brain in Insectivora was characterized by: well developed nucleus infundibularis, less developed nucleus dorsomedialis compared to nucleus ventromedialis, weakly pronounced differentiation of the periventricular part, and lack of nucleus tuberis lateralis. From among the Insectivora under study, cytoarchitectonics of tuber cinereum in mole and common shrew was more or less similar, while it differed from that of hedgehog, in which nucleus dorsomedialis and nucleus hypothalamicus parvocellularis were less developed, nucleus ventromedialis was different, and so was cell structure of nucleus infundibularis.
