title: Cortical evoked potentials on stimulation of pudendal nerve in women.
abstract: Somatosensory evoked potentials were recorded in five normal women on percutaneous stimulation of the pudendal nerve. A consistent response was obtained over the scalp 2 cm behind the Cz electroencephalographic recording site. The latency of onset of this response had a mean value of 33 msec, and the mean latency of the first positive peak was 39.6 msec. This test has potential clinical value in the evaluation of patients with bowel, bladder, or sexual dysfunction when a neurologic causation is suspected.
