[Topography of cell populations of the solitary tract nuclei of rats].

At the light level by means of some morphometrical methods topography and morphological peculiarities of certain cell populations in the solitary tract nuclei (STN) of rats have been investigated. Basing on dimensions, form and tinctorial properties studied, as well as on arrangement density of the cells in the STN, 15 cell groups and 3 acellular areas have been distinguished. For designation of the subpopulations revealed a unified nomenclature, integrating the literature data is suggested.
