| Research Abstract |
When dissimilar images are presented to the two eyes, binocular rivalry (BR) occurs, and perception alternates spontaneously between the images. There are substantial individual differences in perceptual alternation rate during BR. Our fMRI study revealed that the individual’s brain activity in early visual areas evoked by the suppressed stimulus during BR predicts the suppression duration during BR. This suggests activity in early visual areas contributes dynamics of visual awareness during BR.
