[Nuclei and fields of the rabbit hypothalamus].
Common features and distinctions in the structure of certain fields of the rabbit hypothalamus were established on the basis of cytoarchitectonical and cytological analysis. It has been shown that there are three types of nerve cells in the nuclei and fields of the hypothalamus which can be referred to somato-, cyto- and karyochromic elements of the nervous system in accordance with the Nissl classification. All the cellular structures of the hypothalamus can be divided into heteromorphic and isomorphic types. The medial and lateral hypothalamic fields of all the rostro-caudal length of the hypothalamus are referred to the first type. The hypothalamic nuclei occupying its basal part are referred to the second type. On the basis of the obtained data concerning the neuronal composition of the fields and nuclei of the hypothalamus, it can be divided into three zones: the medial zone, including 3 medial hypothalamic fields disposed along the 3d ventricle; the lateral zone comprizing two a lateral hypothalamic fields occupying its lateral parts along its all length and the basal zone including hypothalamic nuclei disposed mainly in the ventral part of the hypothalamus.
