Prophylactic zinc and therapeutic selenium administrations improved spatial learning and memory. A) Five-day learning test in the Morris water maze. Memory was evaluated over days post-learning, as shown in the headings (B, C, D, and E). Values represent the mean ± SEM of 6 rats and their statistical differences were analyzed using a two-way ANOVA. Statistical significance was indicated as *P < 0.05, or **P < 0.01, when compared to the Control group, and †P < 0.05 and ††P < 0.01, vs. the CCAO group.
