Prior knowledge is essential for the beneficial effect of targeted memory reactivation during sleep


Groch, Sabine; Schreiner, Thomas; Rasch, Björn; Huber, Reto; Wilhelm, Ines (2017). Prior knowledge is essential for the beneficial effect of targeted memory reactivation during sleep. Scientific Reports, 7:39763.

Abstract

Prior knowledge speeds up system consolidation and accelerates integration of newly acquired memories into existing neocortical knowledge networks. By using targeted memory reactivations, we demonstrate that prior knowledge is also essential for successful reactivation and consolidation of memories during sleep, both on the behavioral and oscillatory level (i.e., theta and fast spindle activity). Thus, prior knowledge is a prerequisite for new memories to enter processes of system consolidation during sleep.
