Memory reactivations and consolidation: considering neuromodulators across wake and sleep

Abstract

Memory reactivations occur during different states and behaviours and they may serve a multitude of functions. In this review we summarize differences in content, participating brain regions and neuromodulatory milieu of these reactivations. Further, we highlight how such differences could lead to the same phenomena of memory reactivation having different possible functions and outcomes such as memory retrieval, cellular consolidation and systems consolidation.
