Figure 2. Evaluation of the spatial learning and memory of db/db (n=8) and db/m (n=8) by MWM test. (A) The number of platform crossings (n); (B) escape latency (s); (C) times spent in the target quadrant (s); (D) typical swimming paths to reach the original position of the platform. The values presented are mean ± SEM. **p<0.01, #p<0.05 and ## p<0.01 as determined by the two-tailed unpaired Student’s t test.
