REM sleep prefrontal high-frequency oscillation chains mediate distinct cortical-hippocampal reactivation patterns compared to NREM sleep

This study identifies distinct cortical-hippocampal reactivation patterns during REM and NREM sleep, mediated by prefrontal high-frequency oscillation chains in rodents.

Neuromodulation via muscarinic acetylcholine pathway can facilitate distinct, complementary, and sequential roles for NREM and REM states during sleep-dependent memory consolidation

The paper uses a computational model and in vivo recordings to show NREM and REM sleep have distinct roles in memory consolidation, with NREM expanding memory traces and REM preventing overlap.
