[Quantitative characteristics of cellular elements in human cerebellar nuclei at different age periods].
Cellular elements in cerebellar nuclei were studied in humans aged 22-90 years. Series of horizontal sections of cerebellar nuclei, stained with hematoxylin-eosin, were examined. Numbers of neurons and glial cells were determined in standard section area and their ratio (glial index) was calculated. It is established that in the process of aging the number of neurons decreases, while that one of glial cells increases. The degree of these changes increases in the process of ontogenesis.
