Retrieval labilizes memory traces and these gates two protein synthesis-dependent processes in the brain: extinction, which inhibits further retrieval, and reconsolidation, which may enhance retrieval or change its content. Extinction may itself suffer reconsolidation. Interactions among these processes may be applied to treatments of fear memories, such as those underlying post-traumatic stress disorders.
