    The work is based on the results of histological and immunohistochemical studies performed on the sectional material of 104 human corpses (59 men and 45 women) of young and old age. A comparative analysis of the morphological characteristics of the corpus callosum tissues using hematoxylin and eosin staining, the Nissl method (by Snesarev), by Van Gieson, by Spielmeyer, by Foot. An immunohistochemical study of the samples used a panel of antibodies to glial fibrillar acid protein (GFAP), the S-100 protein. It was found that by senile age, the tissue of the corpus callosum is characterized by the accumulation of glial macrophages. With age, there is a proliferation of GFAP-immunopositive astroglia. There is no dynamics of S-100 protein expression with age. Thus, the revealed regularity of age-related variability of the cytoarchitectonics of the corpus callosum is of interest in diagnostic and therapeutic work, and its morphological picture in old age can serve as an equivalent of the anatomical norm.
