Abstract
The fate of memories depends mainly on external and internal factors affecting cellular and systems consolidation on the one hand and the decay or weakening of the memory trace on the other hand. Over the past 40 years, research has focused on the mechanisms of memory consolidation, retrieval, and its consequences: extinction and reconsolidation. In contrast, much less is known about the molecular mechanisms required for the maintenance of memory storage and forgetting. These opposing forces are both activity‐ and time‐dependent. Here, we summarize the molecular signatures and inherent mechanisms involved in memory persistence and active forgetting, highlighting recent findings on the role of dopamine neurotransmission, intracellular signaling cascades, and actin cytoskeleton dynamics in these processes. imageKeywords
