The subiculum is still an understudied part of hippocampal pharmacy. According to histological terminology, the following layers are distinguished in the subiculum: molecular, pyramidal, multiform, perforating tract, tray, commissure of the arch, layers of dorsal and ventral fibers. In the presubiculum there are molecular, outer and inner small pyramidal, reticular, pyramidal and multiform layers. Parasubiculum contains molecular, pyramidal and multiform layers. II, the main layer, is formed by the perikarya of large pyramidal neurons. The dentate gyrus (parahippocampus) in the anterior part of the brain is located under the hippocampus proper, and in the posterior part it is medial to it. It consists of three layers. There are 9 types of neurons in these layers. The data presented in the article can serve as a fundamental basis for further study of the parts of the rat brain in normal and pathological conditions with further extrapolation of the obtained data to humans.
