visual evoked potential

In the field of neuropsychology, a visual evoked potential is an evoked potential caused by sensory stimulation of a subject's visual field. Commonly-used visual stimuli are flashing lights, or checkerboards on a video screen that flicker between black on white to white on black (invert contrast). Visual Evoked Potentials are very useful in detecting blindness in patients that cannot communicate, such as babies or non-human animals. If repeated stimulation of the visual field causes no changes in EEG potentials, then the subject's brain is probably not receiving any signals from his/her eyes. The term "visual evoked potential" is used interchangeably with "VEP", and "visually evoked potential".
