We examined 16 healthy adults in order to evaluate the hypoglossal nerve using magnetic stimulation. Surface electrodes were located in apex and anterolateral third of tongue. We stimulated two sites of head, vertex and occiput.

For occiput stimulation, the mean latency was 3.77±0.32 msec in male and 3.81±0.36 msec in female, for vertical stimulation, 6.94±0.56 msec, 6.91±0.52 msec respectively. For occiput stimulation, the mean amplitude was 4.84±2.80 mV in male and 5.09±2.88 mV in female, for vertical stimulation, 1.96±1.34 mV, 1.15±0.64 mV respectively.
