Novel object recognition test in 11-month-old mice. a Schematic diagram of the novel object recognition test. b, c The cognition index of short- and long-term memory assessed in 11-month-old mice using a new object recognition test (n = 5 in each group). d, e Time spent on the old and novel objects during short-term and long-term memory tests. f Traveled distance determined during the acclimatization period. Data are presented as the mean ± SEM. Data are compared using two-way ANOVA with Bonferroni post hoc test d, e and one-way ANOVA with Tukey post hoc test a–c, f. *P < 0.05; ***P < 0.001
