Visually Evoked Potentials | Detailed explanation of visually evoked potentials. The terms visually evoked potential (VEP), visually evoked response (VER) and visually evoked cortical potential (VECP) are equivalent. They refer to electrical potentials, initiated by brief visual stimuli, which are recorded from the scalp overl... | Text |
