The neural correlates of consciousness (NCC) for auditory awareness include auditory awareness negativity (AAN) and late positivity (LP), but it is unclear which is the true NCC. By inducing simple auditory hallucinations through a Pavlovian conditioning paradigm, where participants rated near-threshold tones and stimulus-absent trials, AAN appeared as an early event-related potential difference between aware and unaware stimuli, suggesting it is a genuine NCC for auditory consciousness. Late positivity was absent in these hallucinations, indicating it may not be essential for auditory awareness.
