| Popis: | Feeding habitats and behavior are connected with various environmental conditions and anatomical structures of the hippocampus, altogether with proteins expression level that may enhance their cognitive memory abilities. The current study investigated the cytoarchitecture anatomical variations, the differences in the hippocampus volume, and the distribution of the proteoglycan agrin and ryanodine receptor protein expression; in the brain hippocampus complex of three avian species (the hooded crow (Corvus cornix, food caching), the cattle egret (Bubulcus ibis, non-food caching), and the rock dove pigeon (Columba livia, food caching). The histological results demonstrated that the anatomical brain structure and cytoarchitecture did not reveal specific characterizing features expect for the hooded crow with large-sized soma. Immunohistochemical staining of hippocampus complex for agrin proteoglycans and ryanodine receptor calcium channels proteins showed a significant increase among the hippocampus of Corvus cornix brain in the medial hippocampus (HCm) and lateral hippocampus (HCl) with value P |
