Abstract

A subject viewed a different grating target with each eye in a binocular rivalry situation and continuously indicated with a response key which target he was seeing. Each target was illuminated with flickering light at different frequencies superimposed upon a steady background. The evoked cortical responses were tape-recorded and later analyzed by average response computer separately for each eye, seeing and not seeing. Differences in latency and amplitude of the evoked responses were found in comparing the dominant and suppressed conditions of the same eye.
