Fig. 1. Behavioral assessment of pterostilbene administration effects on cognitive abilities. (A) T-Maze: while there was no alternation difference between the two groups before the treatment (p = 0.619), Pt-treated animals performed better than controls after pterostilbene administration (p = 0.013). (B) OCT: the Pt-treated group was able to discriminate between the two objects significantly better than the control group (p= 0.003). (C, D) vORT: Pt-treated rats improved their performance compared to control rats, and were able to discriminate between the two objects at both 1 and 24 hours (p<0.001 and p = 0.002, respectively). Histograms represent average values ± SEM. *, p<0.05; **, p<0.01; ***, p<0.001. Two-way RM ANOVA, Holm-Sidak method. N = 7 for the control group and N = 8 for the treated group.
