Somatosensory trigeminal (V2 and V3) potentials were evoked in 20, healthy, Senegalese subjects (10 men and 10 women). Norms hereby established differ little from those in literature, doubtless because skull patterns do not sufficiently influence the latency or morphology of these potentials, and because the racial factor plays no role here, not even with respect to size as in quoted somatosensory potentials for the extremities.
