Tracking rivalry with neural rhythms: multivariate SSVEPs reveal perception during binocular rivalry.

A novel multivariate spatial filter called Rhythmic Entrainment Source Separation can extract steady-state visual evoked potentials from EEG data to quantify perceptual switch rates during binocular rivalry without requiring self-reports. This method may be valuable for studying consciousness in contexts where self-reports are problematic or impossible. The analyses also indicate that no-report conditions may affect attention deployment and thereby neural correlates, an important consideration for consciousness research.
