( Natural News ) Targeted memory reactivation (TMR), a procedure which presents learning-related cues during sleep, can better strengthen memory when it is accompanied with undisturbed sleep to encourage memory consolidation, according to a study in the journal Sleep Spindles & Cortical Up States . Previous studies have shown that an undisturbed short plastic period after cueing is needed for TMR to be effective. Therefore, researchers from Université libre de Bruxelles in Belgium looked at the effect of verbatim or interfering auditory presentation during wakefulness or non-rapid eye movement (NREM) sleep and its impact on memory consolidation. The researchers recruited 96 participants for the study. The participants were tasked to study a list of 40 word pairs that were presented both visually and aurally. During a consolidation interval of 90 minutes spent either awake or asleep, the researchers provided the first word of 20 of the pairs aurally, succeeded by its correct (verbatim) or incorrect (interference) association. After that, they assessed memory for all pairs. Results revealed that the participants in the wake conditions showed improvement in their memory after verbatim cueing; however, their memory weakened after an incorrect association was presented, when compared with uncued word pairs. On the other hand, the targeted memory reactivation or sleep did not affect the memory consolidation of the participants in the nap conditions. Moreover, time-frequency assessments indicated that increased spindle-related sigma activity succeeds the presentation of the first word during NREM sleep. This indicated that the reactivation of the related memory content was instigated. On the other hand, the immediate presentation of the second word, either correct or incorrect, led to the elimination of sigma activity.
