Sleep's Role in Shaping and Strengthening Our Memories
TL;DR
A new theory suggests that the sequence of sleep stages—non-REM followed by REM—is crucial for strengthening and organizing memories, with non-REM sleep reinforcing memories and REM sleep pruning overlapping ones, supported by mouse studies and computational models. Reversing this order impairs memory, highlighting the importance of sleep architecture in learning and memory consolidation.
