Somatosensory evoked potentials (SEPs) to unilateral or bilateral posterior tibial nerve (PTN) stimulation and to stimulation of the dorsal nerve (DN) of the penis/clitoris were recorded on 32 channels in 10 volunteers. SEPs to unilateral PTN stimulation consisted of the classic 'W' complex P38-N45-P56-N75 maximal on the ipsilateral central and parietal leads, and two negative waves, N33 and N37, maximal on the contralateral post- and prerolandic areas, respectively. A lemniscal P30 was also recorded. Bilateral PTN stimulation caused, by algebraic summation, the disappearance of both N33 and N37; the W complex was symmetrical and the amplitude of P30 increased. The SEPs to DN stimulation were also symmetrical, and N33 and N37 were absent. These features can be explained by the bilateral character of DN stimulation. They also differed from bilateral PTN SEPs in 3 respects; the absence of P30, the small amplitude and the weaker gradients of field distribution of the 'W' complex, and the somewhat different distribution of penile from clitoral or bilateral PTN, N45 and P56. These differences can be explained both by physiological (the different fiber composition of the DN) and anatomical (the deeper localization of the DN cortical receiving area) mechanisms.
