Evoked potentials (Electrophysiology)
Processing of Visual Evoked Potentials using Mode Deviation
... VEPs initiated by strobe flash were noticed in the early years of clinical encephalography (EEG) in the 1930s. A VEP can often be seen in the background EEG recorded from the occipital scalp following a flash of light. ...
