Definition

Evoked potentials are waveforms that can be recorded from a peripheral nerve, spinal cord, or cerebral cortex after stimulation of a peripheral nerve. They are named based on the pathways stimulated. Somatosensory evoked potentials (SSEPs) are recorded after stimulation of upper or lower extremity peripheral nerves. Visual evoked potentials (VEPs) are cortical responses measured after visual input. Brainstem auditory evoked potentials (BAEPs) are cortical responses measured after timed auditory stimuli.

Current Knowledge

Evoked potentials have many clinical and research implications. Using sensory and motor pathways, intraoperative monitoring can be used to follow functional integrity of pathways during spinal and intracranial neurosurgical procedures. SSEPs can also be used diagnostically to delineate the location of lesions, such as peripheral nerve or spinal cord. The use of cortical evoked potentials, such as VEPs and BAEPs, can also supplement neuroimaging information...
