[Plastic changes in the sensory elements of the spinal cord after decreasing the afferent inflow]. / Plasticheskie izmeneniia sensornykh élementov spinnogo mozga posle umen'sheniia afferentnogo pritoka.

After partial deafferentation of one of the hindlimbs changes of the cord dorsal potential and mass discharge from the anterior-lateral filament of the exposed spinal cord were studied after maximal recovery of function of the deafferented limb in adult cats. Neuronal activity in response to electrical stimulation of the dorsal roots was considerably higher on the deafferented side than on the intact one. This seems to be due to plastic properties of the c. n. s. responsible for the recovery of functions.

The hindlimb deafferentation was found to entail disorders of the motor activity and sensitivity, as well as a decrease in the evoked activity in the cortical somatosensory areas, although in a lesser degree than transection of the same amount of dorsal roots innervating the forelimbs. Apparently, the afferent organization of the cat hindlimb is different from that of the forelimb. This accounts for preservation of a part of the afferent inflow from periphery to the cortex after partial deafferentation, as well as for the considerable rehabilitation of functions of deafferented hindlimb.
