Figure 5. Spatial reference memory.

Figure 5

Barnes maze test was performed to assess spatial reference memory. There was no significant difference in latency (A) and number of errors (B) to reach the target hole during the training period. (C) Probe trial conducted 1 day after the last training session. The results were analyzed using two-way ANOVA followed by Fisher’s PLSD post hoc test. A significant difference was found in the effect of (genotype) × (hole position ( = distance from target)) interaction (F 11,418 = 2.989, p = 0.0008), although the difference of the time spent around the target did not reach a statistically significant level (genotype effect, F 1,38 = 4.003, p = 0.0526).
