Data are mean ± SD, n = 5 per dose. ∗∗P < 0.01, and ∗∗∗P < 0.001, compared to scopolamine treated group (H2O + Scop), one-way ANOVA followed by Dunnett's bilateral comparisons. bP < 0.01 compared to normal control group (H2O + H2O), one-way ANOVA followed by Dunnett's bilateral comparisons. H2O: distilled water, Pira: piracetam 200 mg/kg, Scop: scopolamine 1 mg/kg.
