[The possible pathways of age-related inhibition of the spinal generators of motor excitation in rat pups].
In experiments on rat puppies, it has been demonstrated that cutting the dorsal part of the spinal cord at the 10th day of postnatal life results at the 17-18th day in a relative hyperactivity, which is revealed in significantly higher volume of the spontaneous motor activity, duration and number of discharges, as well as in significant facilitation of reactions of late discharge type. Therefore, in rat puppies, the pathways of age inhibition of the activity of spinal pacemakers of motor excitation are located in dorsal and dorsolateral parts of the spinal cord.
