Figure 1.

Schematic representation showing the effect of post-reactivation propranolol on reconsolidation. In rodents, conditioning typically consists of a single CS-US pairing (left). The next day animals receive 1 CS reactivation trial, immediately followed by propranolol or vehicle administration (middle). When tested at later time points in the absence of drug, propranolol treated animals show reduced fear responding (right). Abbreviations: baseline period (BL), injection (INJ), vehicle (Veh), propranolol (Prop).
