For a long time, consolidation was seen as a process achieved only on newly acquired memories aimed to store them for the long term. However, pioneer and recent studies have demonstrated that after retrieval, long-term memories may once more undergo a consolidation-like process referred to as reconsolidation. Mainly, reconsolidation is sustained by the now widely reported observation that after a memory trace is activated by means of retrieval and is susceptible to disruption by the same treatments that disrupt memory during consolidation. However, the functional purpose of this process is still a matter of debate.
