Reduced neural feedback signaling despite robust neuron and gamma auditory responses during human sleep

Published in Nature · View the paper (DOI)

Researchers found that despite a powerful brain response to sound during sleep, the level of alpha-beta waves associated with attention and expectation is significantly reduced. This means the brain can analyze auditory input but fails to focus on it, resulting in no conscious awareness.
