Effect of systemic administration of MDZ and PROP on memory reconsolidation in animals without memory reactivation.

(A) Timeline for non-reactivated rats from Experiment 1. (B and C) In the absence of the re-exposure session, neither MDZ nor PROP, respectively, reduced the freezing response on Test 1. (B) CON-SAL (n = 7), CON-MDZ (n = 7), ETOH-SAL (n = 7), and ETOH-MDZ (n = 8). (C) CON-SAL (n = 9), CON-PROP (n = 8), ETOH-SAL (n = 9), and ETOH-PROP (n = 11). Data are the mean ± standard error of the mean of time spent freezing during Test 1. CON, control rats; ETOH, ethanol-withdrawn rats; MDZ, midazolam; PROP, propranolol; SAL, sterile saline.
