Recording monocular VEPs under binocular conditions.
This report describes a technique for recording the visual evoked potential (VEP) arising from 1 eye under conditions of binocular pattern stimulation. The subject views a sinusoidally modulated vectographic checkerboard with orthogonally oriented polarizing filters before the eyes. This technique results in waveforms that contain monocular VEPs distributed in time. The technique is sensitive to interocular suppression and controls for the influence of various extraneous sources of variability. It is useful in clinical VEP testing.
