How memories are formed and stabilized has been a central question for decades. Recent research has shown that reactivating apparently stable memories can render them fragile and open to modification and to another round of stabilization in a process called reconsolidation. Hupbach et al. explored the conditions leading to the updating of episodic memory. They found that memory plasticity at reactivation provides a mechanism for updating memories, and that the latter are determined by the spatial context; that is, the “where” of episodic memory. Only when the memory was reactivated in the same context as when it was learned could new learning be incorporated into the existing store of knowledge; if reactivated in a new context, no updating occurred. — PRS
