[The structure of the higher sections of the motor system in the rat brain after different forms of hypokinesia].
Composition of structural elements and different types of glial cells of caudate nucleus head were studied after 40, 90 and 120 days of intensive and 90 days of non-stress hypokinesia. In small portion of neurons and synapses non-stress hypokinesia causes changes basically indicating their low activity while intensive hypokinesia leads to more significant disorders. Motor area retains almost normal structure in both forms of influence. Decrease of spine number and variability is characteristic. Number of neurons with satellites and separate satellite forms in intensive hypokinesia significantly increases in different cortical layers. Oligodendrocyte and astrocyte number grows appropriately in surface and deep layers.
