NREM Sleep Enhances Cognitive Performance

A new study reveals how NREM sleep enhances cognitive performance by synchronizing neural activity and improving information encoding. Researchers observed macaques' brain activity during visual tasks before and after sleep, finding that neuronal desynchronization after NREM sleep led to better task performance.
