A new study reveals that the human brain may process visual information differently depending on whether the person is awake or asleep, challenging long-held assumptions about how perception works during sleep. Researchers found that while awake, the brain rapidly integrates visual cues to form a coherent picture, but this process appears to slow or alter during sleep stages. The findings suggest that even when asleep, the brain retains some capacity to register and interpret visual stimuli, though in a fragmented or less structured manner. This discovery could reshape understanding of sleep perception and its potential implications for memory consolidation and sensory processing.
