RealFeedApp Sleeping brains filter out neighbor sounds
During sleep, the brain actively processes sensory signals, generating illusions of sounds that do not exist. Research indicates this occurs due to changes in information processing rather than a shutdown of consciousness.

- the brain and neuroscience
- What they did
- Researchers studied how the brain processes sounds during the transition from wakefulness to sleep and found that it tends to perceive insignificant sounds as louder.
- Why it matters
- This helps explain the mechanisms behind false dreams and night terrors, where the brain interprets random noises as a threat.
