Abstract
The nervous system is one of the leading integrating systems of the body. In combination with the cardiovascular and endocrine systems, it unites the body into a single whole. The nervous system controls the level of adaptive reactions of a living organism to changing environmental conditions. The Nile bat (Rousettus aegyptiacus) is a typical representative of the order bats. The purpose of our study is to study the macromorphology of individual anatomical structures of the brain of the Nile bat (Rousettus aegyptiacus). The material for the study was four different-sex animals of the Nile bat species (Rousettus aegyptiacus) aged 10-14 years, obtained from private veterinary clinics. The methods for studying the brain of the Nile bat were: fine anatomical dissection, morphometry, photographing, weighing. The work was performed on the basis of the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine. As a result of the study, it was found that due to the strong development and large size of the auditory posterior tubercles of the quadrilateral, it is possible to judge the predominance of the auditory analyzer, while the anterior tubercles of the quadrilateral have a relatively small size, most of the structures of the visual analyzer are contained in the neocortex. It was found that there is no division of the cerebellar fragment into anatomical structures in the brain, and the size of the flocculonodular lobe of the cerebellum in this species is on average 1.30x1.10±0.15x0.10 mm. The absence of pronounced lobes and furrows was revealed, and the Nile bat (Rousettus aegyptiacus) belongs to lysencephalic animals. The obtained materials can be used as a reference material for continuing research on the brain of the Nile bat (Rousettus aegyptiacus), as well as in comparative morphology and physiology of humans and animals.
