The aim of the research was to characterize the topography and cytoarchitecture of the hippocampus in the American mink (Neovison vison). The hippocampal formation is a neural structure of the rhinencephalon which stretches from the splenium of the corpus callosum to the ventromedial angle of the cerebral hemisphere. The hippocampal formation is subdivided into regions, layers, and fields (CA1-CA4). The brains of six sexually mature American minks were used in the study. The material collected was mounted in paraffin, and the paraffin blocks were cut into slices. Morphological examinations were carried out with an Olympus BX40 light microscope. The dominant neurons in the hippocampus proper and the subiculum are pyramidal cells. The neurons are morphologically different in each of areas CA1-CA4. Small, loosely arranged neurons form 2-3 layers of cells. In areas CA1-CA3 the neurons are densely packed, forming 5-6 layers of cells. Most of them are pyramidal in shape, with large round or oval nuclei. Area CA4 contains loosely scattered cells of a pyramidal layer located near the entrance to the sinus of the dentate gyrus. The regio superior is a part of hippocampus adhering to the subiculum, whereas the regio inferior adheres to the dentate area.
