Brain caught ‘filing’ memories during rest

Memories formed in one part of the brain are replayed and transferred to a different area of the brain during rest, according to a new study in rats.The finding suggests that replay of previous experiences during rest is important for memory consolidation, a process whereby the brain stabilizes and preserves memories for quick recall in the future. Understanding the physiological mechanism of this is essential for tackling amnesiac conditions such as Alzheimer’s disease, where memory consolidation is affected.
