Related to somatosensory evoked potential: Somatosensory Evoked Response

so·ma·to·sen·so·ry e·voked po·ten·tial

the computer-averaged cortical and subcortical responses to repetitive stimulation of peripheral nerve sensory fibers.

somatosensory evoked potential (SEP)

[-sen′sərē]
Etymology: Gk, soma + L, sentire, to feel
evoked potential elicited by repeated stimulation of the pain and touch systems. It is the least reliable of the evoked potentials studied as monitors of neurological function during surgery.
