New paper alert!: Is the P300/P3b a neural signature of perceptual awareness? We combined a visual masking paradigm with a no-report paradigm and found that it is not.
To identify the neural correlates of perceptual awareness, researchers often compare the differences in neural activation between conditions in which an observer is or is not aware of a target...

very interesting! wanted to add that P3 has been dissociated from conscious vision also in a report-paradigm: participants can report conscious detection of a visual stimulus before P3 onset.
