Travel time on open‐field test at juvenile and adult stages. For juvenile, n = 13 for WT mice and n = 13 for KO mice. For adult, n = 8 for WT mice and n = 7 for KO mice. *P < 0.05; one‐way ANOVA with Bonferroni's post hoc test (juvenile: F(1, 24) = 5.87, adult: F(1, 13) = 2.55). Data are presented as mean ± SEM.
The velocity in the open‐field test at juvenile and adult stages. For juvenile, n = 13 for WT mice and n = 13 for KO mice. For adult, n = 8 for WT mice and n = 7 for KO mice. One‐way ANOVA with Bonferroni's post hoc test (juvenile: F(1, 24) = 1.74, adult: F(1, 13) = 0.17). Data are presented as mean ± SEM.
Time in center (%) on open‐field test at juvenile and adult stages. For juvenile, n = 13 for WT mice and n = 13 for KO mice. For adult, n = 8 for WT mice and n = 7 for KO mice. *P < 0.05; one‐way ANOVA with Bonferroni's post hoc test (juvenile: F(1, 24) = 5.75, adult: F(1, 13) = 0.63). Data are presented as mean ± SEM.
Grooming time in open‐field test at juvenile and adult stages. For juvenile, n = 13 for WT mice and n = 13 for KO mice. For adult, n = 8 for WT mice and n = 7 for KO mice. **P < 0.01; one‐way ANOVA with Bonferroni's post hoc test (juvenile: F(1, 24) = 7.84, adult: F(1, 13) = 0.31). Data are presented as mean ± SEM.
Olfactory function test at adult. n = 13 for WT mice and n = 21 for KO mice. One‐way ANOVA with Bonferroni's post hoc test (F(1, 32) = 0.21). Data are presented as mean ± SEM.
Cage‐top hang test at adult. n = 10 for WT mice and n = 16 for KO mice. One‐way ANOVA with Bonferroni's post hoc test (F(1, 24) = 0.32). Data are presented as mean ± SEM.
Three‐chamber social interaction test at adult. Total time spent in each chamber. n = 19 for WT mice and n = 20 for KO mice. Two‐way ANOVA followed by Scheffe's post hoc test (main effect of genotype F(1, 96) = 0.E+0, main effect of chamber F(2, 96) = 282, interaction F(2, 96) = 3.26). Data are presented as mean ± SEM.
