EEG and eye-events relating to perceptual switching in the Necker cube

We studied perceptual switching in relation to EEG and eye-events such as blinks and saccades during 240 second continuous presentations of the Necker cube. Participants indicated switches by button presses. At several moments prior to, during, and after the button presses, the frequency of EEG and eye-events deviates significantly from the average. The results indicate that perceptual switching processes belong to a number of distinct categories. Eye-events have multiple properties in the process; some facilitate perceptual switching and the other are consequences of it. The pattern of EEG shows discrete variety depending on the properties of the eye-events.
