[Recovery of function following incomplete section of the posterior funiculi of the spinal cord].

The course of functions recovery and the changes of somatosensory cortical evoked potentials were studied in cats after incomplete dorsal funiculi section at the cervical level. The restoration of functions was more rapid and complete in animals with the partial section as compared with those with complete dorsal funiculi section. The latter had no evoked potentials recovery. Undamaged fibers were concluded to be able to send a significant afferent inflow from the periphery to the cortical somatosensory areas and, apparently, to play an important role in the process of the compensatory reorganisation.
