Visual evoked potentials of adaptation to left-right reversed vision.

During the course of the adaptation to left-right reversed vision, visually, evoked potentials (VEPs) were measured for a light flash presented on either side of a fixation. The VEP amplitudes and latencies changed drastically as the adaptation progressed. The time course of the change was quite different between occipital scalp loci. These results indicate that the adaptation to the optical distortion takes place even in the relatively early stage of the visual information processing.
