Brain turns listening inward during REM sleep, EEG recordings suggest
New EEG recordings during REM sleep reveal that the brain shifts its focus from external stimuli to internal processing, a finding that could reshape our understanding of dreaming and memory consolidation. The study, published in a leading neuroscience journal, observed distinct neural activity patterns suggesting the brain 'listens' to its own signals during this sleep phase.
During REM sleep, the brain appears to prioritize internal signals over external ones, a shift that may be key to how we process memories and emotions.
