Binocular Rivalry and its neural processing in cortical hierarchy

binocular rivalry

It has been a mystery as to what level of cortical hierarchy is suppressed in visual processing from the amblyopic eye and how neural representations change when increasing contrast or paying attention to the amblyopic eye. In this project, we will adapt a standard EEG binocular rivalry paradigm, which modulates stimuli at different frequencies in each eye and incorporates a behavioral measure of perceptual eye dominance. We will simultaneously measure neural activity along the cortical hierarchy and perceptual eye dominance under 3 conditions: equal contrasts in the two eyes, perceptually balanced contrasts in the eyes, and paying attention to the amblyopic eye under equal contrasts.
