To study the effect of voluntary concentration on the visual evoked potential (VEP) with monocular and binocular rivalry stimulation, pattern reversal VEPs were recorded using 5.5 min arc and 50 min arc check sizes. Subjects viewed the VEP stimulus with the left eye and a light emitting diode (LED) with the right eye. They were asked to concentrate on(More)
The influence of neutral density (ND) filters on the pattern visually evoked response (VER) was investigated as a function of check size. Monocular and binocular transient pattern reversal VER's were recorded through three ND filters (0.6, 1.0, and 2.6 log units) before 1 eye on 55 adult subjects using 5.5 min arc and 50 min arc check sizes. The 5.5 min arc(More)
The effect of induced fixation disparity produced by negative lenses and base-in prisms on the pattern visually evoked potential (VEP) was investigated. Monocular and binocular pattern reversal VEP were recorded through the negative lenses and base-in prisms using a 9.5 min arc check size. The results suggest that the mean binocular amplitude was 27% larger(More)
