  • Look Inside

Somatosensory evoked magnetic fields (SEF) in humans were reviewed. SEF are usually recorded following percutaneous electrical stimulation applied to the trunk of peripheral nerves such as the median nerve or tibial nerve or following tactile stimulation to the skin. In general, peak latency of the primary component is approximately 20 and 40 msec following stimulation of the upper and lower limb, respectively, and it is variable at the stimulatory site.
