Abstract

When we look at ambiguous figures, perception spontaneously changes from one to the other (perceptual alternation). We measured the brain activity from subjects who observed the Necker cube, one of the most famous ambiguous figures, using magnetoencephalography (MEG). To identify the brain activity inducing perceptual alternation, we propose a novel change-point detection method using spectral clustering to recurrence plots, and apply to measured data. Synchronized activity changes were detected at parietal channels.
