Page "Evoked potential" Paragraph 3

Sensory evoked potentials ( SEP ) are recorded from the central nervous system following stimulation of sense organs ( for example, visual evoked potentials elicited by a flashing light or changing pattern on a monitor ; auditory evoked potentials by a click or tone stimulus presented through earphones ) or by tactile or somatosensory evoked potential ( SSEP ) elicited by tactile or electrical stimulation of a sensory or mixed nerve in the periphery.

They have been widely used in clinical diagnostic medicine since the 1970s, and also in intraoperative neurophysiology monitoring ( IONM ), also known as surgical neurophysiology.
