Evoked potentials (EPs) are neural responses time-locked to some stimulus. Used clinically and in research, EPs are objective physiological markers of clinically relevant abnormalities in sensory or motor systems. In this article, clinical applications of event-related potentials (P3 or P300) and visual, somatosensory, brain stem auditory, motor, and premotor EPs are discussed. The use of EPs for intraoperative neuromonitoring is also discussed. An overview of the methodology of clinical EP recording is provided, with a description of pathologic and nonpathologic factors that can significantly alter EPs.
