            forms of NR1; total form of NR2B (G); phosphorylated (H); and total (I) forms of AKT from the cortical extract of mice that were and were not subjected
            to voluntary physical exercise (sedentary WT [n = 6], sedentary HT [n = 5], exercise WT [n = 6], exercise HT [n = 6], except for AKT (I) sedentary WT
            [n = 5], sedentary HT [n = 5], and exercise WT [n = 4], exercise HT [n = 4]).  (J) Representative bands of each protein. The results are expressed as mean
            ± standard error of the mean and were analyzed by two-way ANOVA followed by Turkey post-test. In (A): *P < 0.05 for sedentary HT versus Exercise HT;
            in (D): *P < 0.05 for exercise group versus sedentary group; in E: *P < 0.05 for WT versus HT.
