Odor Cues During Slow-Wave Sleep Prompt Declarative
Memory Consolidation


Sleep facilitates memory consolidation. A widely held model assumes that
this is because newly encoded memories undergo covert reactivation during
sleep. We cued new memories in humans during sleep by presenting an odor
that had been presented as context during prior learning, and so showed
that reactivation indeed causes memory consolidation during sleep.
Re-exposure to the odor during slow-wave sleep (SWS) improved the retention
of hippocampus-dependent declarative memories but not of hippocampus-
independent procedural memories. Odor re-exposure was ineffective during
rapid eye movement sleep or wakefulness or when the odor had been omitted
during prior learning. Concurring with these findings, functional magnetic
resonance imaging revealed significant hippocampal activation in response
to odor re-exposure during SWS.

P.S：SWS=Slow-Wave Sleep，其實就是大家熟知的NON-REM睡眠，也就是不做夢的階
段。
