| The morphology of neurons and topography of gyrus parahippocampalis in the chinchilla |
| The aim of the research was to learn the structure and topography of gyrus parahippocampalis in the chinchilla (Chinchilla laniger). The examination was carried out on 5 brains of sexually mature chinchillas. The examination material was fixed, dehydrated and embedded in paraffin. Frontal slices were stained according to Klüver and Barrer`s method. Gyrus parahippocampalis, which was the object of the examination, is a cortical structure which joins the hippocampus formation with neocortex. It is a rear part of gyrus fornicatus, which stretches from splenium of corpus callosum to the abdomino-medial angle of the brain hemisphere. It is made up of the following cortical structures: area entorhinalis, parasubiculum and presubiculum. The above-mentioned parts of gyrus parahippocampalis cortex are made up of four layers: marginal layer, external cellular layer, medial cellular layer, and internal cellular layer. |
