Does postbrachial deafferentation modify the cortical responses to forelimb stimulation?
Epidural evoked potential recordings were performed in four macaque monkeys on peripheral nerve stimulation, before and after spinal transection, to evaluate whether the Schiff-Sherrington phenomenon could be demonstrated in this manner. No change in evoked potentials from upper extremity stimulation was seen after mid-thoracic spinal cord transection.
