Perceptual switching is a phenomena that the subjective appearance of multistable stimuli can switch spontaneously during prolonged viewing. This study addresses to extract the dynamical processes in our brain during the perceptual switching to a rotating sphere stimulus. The rotating sphere includes two types of dots moving leftwards and rightwards flickering at a different frequency, which induced the apparent motion direction spontaneously switches. The EEG signals recorded during the perceptual switching showed a significant difference in the SSVEP amplitude in the primary visual cortex between before and after the change of the motion perception.
