ERPs to changes in both eyes.

<p>(a) ERPs averaged within clusters of six electrodes at frontal, temporal, parietal, and occipital regions for the left and right hemispheres involving orientation changes in one eye (rivalry–rivalry—dotted lines and fusion–fusion—solid lines) from the attend-to-grating condition (black lines) and from the attend-to-fixation condition (blue lines). The major ERP components are marked with letters (P1, N1). Again, the N1 is greater in the attend-to-fixation conditions than in the attend-to-grating conditions; this is most pronounced from the occipital sites.
