It is well known that, under certain boundary conditions, the retrieval of a stable consolidated memory results into a labile one. During
this unstable phase, memory can be vulnerable to interference by a number of pharmacological agents, including benzodiazepines. One
of the goals of this study was to evaluate the vulnerability to midazolam (MDZ) after reactivation of recent and remote contextual fear
memories in animals that experienced a stressful situation before learning. Animals were subjected to a restraint session and trained in a
contextual fear paradigm the following day; consolidated memories were reactivated at different times after learning and different MDZ
doses (1.5, 3.0 mg/kg) were administered to
