Enhancing a declarative memory in humans: The effect of clonazepam on reconsolidation

► The GABAergic system is involved in the reconsolidation of a declarative memory in humans. ► No emotional charge and low doses of benzodiazepines determine memory enhancement. ► 0.25 mg of clonazepam followed by a specific reminder induced memory improvement. ► Clonazepam alone or followed by retrieval (no reactivation) didn't show any effect. ► The post-reactivation clonazepam intake didn't affect the short term memory test.
