Neural correlates of consciousness in the sound-induced flash illusion.

ABSTRACT: The visual awareness negativity (VAN) has been identified as a potential neuronal correlate of consciousness (NCC). The VAN is typically found when comparing experimental trials in which a stimulus was perceived with trials in which the same stimulus was not perceived. However, if the VAN represents a reliable NCC, it should also be observed under conditions in which participants report conscious perception despite the absence of a corresponding visual stimulus, i.e., a visual illusion. Our event-related potential (ERP) study (N = 47) aimed to investigate this question by using a suited stimulation design, the sound-induced flash illusion (SIFI), for which a visual stimulus is presented once together with two short beeps, leading - on about half the trials - to the illusory perception of a
