記憶のための睡眠：睡眠が記憶をどう形づくるか | Dr. Abdelrahman Rayan | TEDxHSRW

神経科学者のアブデルラフマン・ラヤン博士は、睡眠は受動的な休息ではなく、脳が活発に働く状態だと論じています。TEDxHSRWの講演では、睡眠が脳による記憶の安定化、再編成、統合をどう助けるかを説明し、一日の出来事の一部が翌日へ引き継がれる仕組みに触れています。講演は神経科学と日常的な睡眠の経験に基づいています。講演者はナイメーヘンのラドバウド大学で、覚醒と睡眠の間で脳の活動がどう変化するかを研究しています。

What happens to your day when we fall asleep? Neuroscientist Dr. Abdel Rayan explores how sleep helps the brain stabilize, reorganize, and integrate memories, turning the day’s experiences into tomorrow's memories. The talk shows that sleep isn't a passive break or wasted time, but an active process in which the brain uses experience to make memories last. Filmed and edited by Fotocinema (Arkadiusz Tomala). Dr. Abdel Rayan is a neuroscientist and founder with a broad background spanning medicine, systems neuroscience, computational neuroscience, and mathematical modelling. His work explores how the brain reorganizes its activity as it moves between wakefulness and sleep, and how these changing brain states support memory consolidation. At Radboud University and Radboudumc in Nijmegen, he uses AI and machine learning to explore sleep states across species, bridging animal and human sleep research to better understand how the brain processes experience and memories during sleep. In his TEDx talk, Abdel invites the audience to rethink sleep: not as a passive break during the night, but as an active brain state in which the brain works with experience and memory. Drawing on neuroscience and the everyday experience of sleep, he explores how the brain stabilizes and reshapes memories, allowing parts of one day to be carried into the next. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
