Figure 5

(A) Outline of the experimental procedure. (B) Freezing time in response to the CS after training was comparable across groups that received bilateral intra-BLA infusion of SN50 or vehicle (vehicle, n = 9; SN50, n = 9). (C) No significant difference in freezing time was observed after bilateral intra-BLA infusion of SN50 or vehicle in the 4 h and 24 h tests between groups (p>0.05). The data are expressed as mean ± SEM. *p<0.01, compared with pre-CS (two-way ANOVA followed by post hoc test).
