Propranolol disrupts memory reconsolidation in the passive avoidance task. Schematic of the behavioral protocols for the consolidation (A) and reconsolidation and no-reactivation (B) procedures. In the consolidation procedure (n = 14 per group), there was no memory deficit in propranolol-injected mice for the latency (±SEM) to enter the dark box (C), nor for the percentage of avoidance of this aversive box (F). However, for the reconsolidation procedure, propranolol-injected mice (n = 8) exhibited decreased memory performance relative to control mice (n = 10) (D,G). In the no-reactivation procedure, propranolol-injected mice (n = 9) showed the same level of avoidance as control mice (n = 8) (E,H). **p < 0.01; ***p < 0.001 NaCl vs. Propranolol.
