Reconsolidation is necessary for the restabilization of reactivated memory traces. However, experimental parameters have been suggested as boundary conditions for this process. Here we investigated the role of a spatial memory trace's age, strength, and update on the reconsolidation process in mice. We first found that protein synthesis is necessary for reconsolidation to occur in the hippocampal CA3 region after reactivation of partially acquired and old memories but not for strongly acquired and recent memories. We also demonstrated that the update of a previously stable memory required, again, a memory reconsolidation in the hippocampal CA3. Finally, we found that the reactivation of a strongly acquired memory requires an activation of the anterior cingulate cortex as soon as 24 h after acquisition. This study demonstrates the importance of the knowledge of the task on the dynamic nature of memory reconsolidation processing.
