title: Absence of spinal N13-P13 and normal scalp far-field P14 in a patient with syringomyelia.
abstract: Short latency somatosensory evoked potentials to median or ulnar nerve stimulation were recorded in a patient with syringomyelia. Scalp-recorded far-field P14 was clearly preserved, but spinal N13-P13 components disappeared. Our findings support the hypothesis that spinal N13-P13 is generated by structures intrinsic to the cervical cord, most likely in the ventral central gray matter.
