Distinct MEG correlates of conscious experience, perceptual reversals and stabilization during binocular rivalry.

During binocular rivalry, when each eye sees a different image, perception alternates between them. Presenting the images intermittently with gaps longer than about 400 milliseconds slows or stops these alternations, a phenomenon called stabilization. Using magnetoencephalography (MEG) in healthy humans, the study found that perceptual content correlates with modulation of stimulus-specific activity in occipital/temporal brain areas 150–270 milliseconds after stimulus onset, possibly reflecting suppression of the non-perceived image. Stability builds gradually across at least ten trials and involves parietal activity.
