Figure 2. Results of the Morris water maze test. A, Escape latency: time to reach the hidden platform. B, Escape distance: length of the swimming path taken to find the platform. C, Cross times: times the mice passed through the platform. D, Total swimming distance in controlled time (1 min). E, Typical escape route (the swimming path of mice) in the 3 groups. *P<0.05, **P<0.01 vs control group; ^#P<0.05, ^##P<0.01 vs model group (one-way ANOVA).
