[The modular organization of the granular layer of the human cerebellar cortex in postnatal ontogeny]

Abstract

Age changes of microstructure of granular layer of the cortex of human cerebellum superior lobe (the area of clivus, posterior lateral regions of right and left tetrangular lobules) were studied in annual intervals from birth up to 20 yrs using computer analysis of optic images. Enlargement of the area of profile fields of cell groups in apical and basal regions of cerebellar folia from birth up to 14-15 yrs and differences between hemispheres in clasterization of granular layer were demonstrated. The data on age changes of cellular aggregations obtained allowed to formulate a hypothesis on autonomic local sensory networks of human cerebellar cortex associated with granular layer of cerebellar cortex that are considered as structural elements of module organization of the latter.
