[Age and changes in nerve endings on the surface of the ependyma of the human brain].
Using scanning electron microscopy, the human brain ependyma was studied in different age groups (18-98 years). Sphere-shaped structures directly connected with the cellular surface were found on the surface of ependymal cells. In patients over 60 years such formations were flattened and deformed, sometimes completely destroyed. The detected age-related changes are considered as manifestations of atrophy of neuronal endings localized on the ependyma surface, which may affect different properties of the cerebrospinal fluid.
