Abstract'Consolidation'has been used to describe distinct but related processes. In
considering the implications of our recent findings on the lability of reactivated fear
memories, we view consolidation and reconsolidation in terms of molecular events taking
place within neurons as opposed to interactions between brain regions. Our findings open
up a new dimension in the study of memory consolidation. We argue that consolidation is
not a one-time event, but instead is reiterated with subsequent activation of the memories.
