Abstract

When the two eyes view large, dissimilar patterns that induce binocular rivalry, alternating waves of visibility are experienced as one pattern sweeps the other out of conscious awareness. Here we combine psychophysics with functional magnetic resonance imaging to show tight linkage between dynamics of perceptual waves during rivalry and neural events in human primary visual cortex (V1).

Comments/Discussion

The third William James Prize for Contributions to the Study of Consciousness was awarded in Oxford England at the 10th Annual Meeting of ASSC to Sang-Hun Lee and colleagues for this article. The research described in this publication combined psychophysics and FMRI to show that there is a tight linkage in humans between the dynamics of perceptual traveling waves experienced during binocular rivalry and the neural events in primary visual cortex (i.e., V1). Sang-Hun Lee received his Ph.D in Visual Neuroscience from Vanderbilt University in 2001. He is presently an Assistant Professor of Psychology and the Interdisciplinary Program in Brain Science at the Seoul National University.
