The age-related inhibition of motor excitation of the spinal cord in the early postnatal ontogeny of rats

In the experiments on the developing albino rats it was investigated the influence of the lesion of dorsolateral funiculus of the spinal cord on the age-related inhibition of the spontaneous periodic motor activity and late long-lasting discharges evoked by stimulation of n. tibialis controlateralis and recorded in m. gastrocnemius. The relative hyperactivity and increased duration of long-lasting discharges after the end of the second week was observed independently of the age of operated animal (3, 5, 10, 12 days after birth).
