Fig. 3. Persistence of the blockade of fear responses to both conditioned stimulus 1 (CS1) and CS2 by the unconditioned stimulus (US)-based memory retrieval interference procedure with propranolol.

Fig. 3

Mean differential skin conductance response (SCR; CS1+ minus CS or CS2+ minus CS) during the fear memory test and reinstatement test after the intervention 2 weeks later. *p < 0.05, comparisons between CS1 retrieval + propranolol (n = 16) and US retrieval + propranolol (n = 14; between-group); #p < 0.05, comparisons between last three trials of test and reinstatement (within-group). The data are expressed as mean ± SEM.
