title: [The structure of the motor cortex in the rat in hypokinesia].
abstract: Ultrastructure of neurons, synapses and glial elements was studied in the rat motor cortex under exposure to hypokinesia lasting for 40 and 90 days. Changes prevail in all cortical layers in 90-days hypokinesia and in upper ones in 40-days hypokinesia. These are basically reactive or not deep destructive changes. Cell elements and synapses with structural manifestations of low functional activity prevail with the increase of the experimental terms. Astrocyte number including satellite forms significantly grows in 40-days hypokinesia. In 90-days changes occur in all cortical layers with the increase of both astrocyte and oligodendrocyte number.
