Abstract In the search for neural correlates of consciousness (NCC), prominent theories disagree about role sensory versus wide-spread fronto-parietal brain activity. Research on auditory awareness has been widely neglected, and isolating NCC from task-related post-perceptual processes (e.g., report) is an ongoing challenge. The present study addressed these issues using functional magnetic resonance imaging (fMRI) during a no-report inattentional deafness paradigm. Sixty-three participants performed distractor task while supra-threshold but task-irrelevant sounds were presented in background. Whereas one group was aware stimuli, another remained unaware. Comparing responses to critical between unaware controlling postperceptual processing revealed that associated with significantly increased activity secondary not areas. These findings suggest dominant stimulus-specific rather than widespread information broadcasting conscious perception.

Negative-going responses in sensory cortex co-vary with perceptual awareness of stimuli. Given that this negativity has also been observed for undetected stimuli, some have challenged its role perception. To address question, we combined magnetoencephalography, electroencephalography, and pupillometry to study how sustained attention response criterion affect the auditory negativity. Participants first detected distractor sounds denied hearing task-irrelevant near-threshold tones, which evoked neither nor pupil dilation. These same tones both when task-relevant, stronger hit but present miss trials. then rated their perception on a six-point scale test whether explains presence these Decreasing ratings were associated gradually reduced responses, consistent signal detection theory. results support concept an is modulated by does not require non-linear threshold mechanism.
