Effect of exercise in the old mice on cognitive performance. (a) DI scores in NORT, calculated with four different exploration time periods in the sedentary (n=9) and exercise (n=7) group. The calculated DI values at each time interval were subsequently averaged across animals. (b-d) Correlations between the daily average running distance and four different DI scores: 1, 2, 3, and 4 minutes, respectively. (f) Spontaneous alteration scores in the Y-maze test in the sedentary (n=9) and exercise (n=7) group. Statistical analysis was carried out using Two-way ANOVA with post hoc Tukey’s in (a) and Student’s t-test in (f). **p<0.01. Please see Supplementary document for exclusions.
