Figure 3. Combination of catalpol promoted the exercise-induced cognitive protection in PTSD mice. (A) The latency escape time of the mice in acquisition test. (B) Time percentage of the mice to swim in the target zone during the probe trail. Two-way ANOVA for acquisition test, *p < 0.05, **p < 0.01, ***p < 0.001. One-way ANOVA for probe trail, ***p < 0.001 vs. control; #p < 0.05 vs. PTSD.
