APA Dictionary of Psychology

a type of evoked potential recorded from electrodes placed on the scalp, overlying the cerebral cortex, in response to sensory stimulation. The stimuli may be visual, auditory, somatosensory, gustatory, or olfactory, and the mapping of sensory evoked potentials in the cortex helps to locate the different sensory areas. See also auditory evoked potential; visual evoked potential. Compare motor evoked potential.
