Consolidated memories may be reactivated by a reminder of the original memory; followed by a process of re-stabilization known as reconsolidation. We have previously observed that the presentation of two consecutive reminders reinforces memory re-stabilization. Furthermore, a 90-min nap after memory reactivation shortened the time window of reconsolidation being SWS sleep EEG slow oscillations involved in this process. However, it is not clear whether it stabilizes the trace protecting the memory against interferences or if it also strengthens the labilized memory making it more difficult for it to be disrupted.
