Single trial prestimulus oscillations predict perception of the sound-induced flash illusion

Abstract In the sound-induced flash illusion, auditory input affects the perception of visual stimuli with a large inter- and intraindividual variability. Crossmodal influence in this illusion has been shown to be associated with activity in visual and temporal areas. In this electroencephalography...
