[Plastic changes in the sensory elements of the spinal cord after decreasing the afferent inflow].

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.
