Fig. 1. Effects of the blueberry drink on the mean time to reach the goal in the multiple T-maze water test on two days in adult rats under chronic mild stress conditions.

(A) mean time to reach the goal on the first day of the multiple T-maze water test and (B) mean time to reach the goal on the second day of the multiple T-maze water test. The data are expressed as the mean ± SE of 12 animals per group. Significant differences between the stress (ST) and blueberry drink (B) or interaction between these factors (ST × B) were tested by two-way ANOVA and expressed as P-values, followed by Fisher's LSD test. Different letters represent statistical differences between the means (P < 0.05).
