Consolidation of second-order fear requires BLA activity. a, Experimental timeline of second-order conditioning and retraining with first-order conditioning. Percentage freezing to (b) S1 across first-order conditioning for bupivacaine- (n = 10) and vehicle- (n = 12) treated rats, (c) S2 and S1 across second-order conditioning, and (d) to S2 across test. Drug-treated rats are shown with filled squares and circle and vehicle-treated rats are shown with open squares. Data are represented as mean ± SEM.
