Abstract
A 30-day motor training of rats started at a month's age does not reduce the duration of the excitability recovery cycles of neuronal populations in the sensorimotor cortex. A three-month training is accompanied by a considerable reduction of excitability recovery cycles. This coincides with a pronounced increase of the average density of spines on the apical and oblique dendrite branches of the pyramidal cells in the cortical layer V, which exceeds that observed after a 30-day locomotor training. In 30 days, the rats with a three-month training reveal a partial recovery of functional and structural parameters, and in two months, approach their initial values.
