Depression-like behavior in Tph2^−/− mice. Forced swim test: (a) Latency to the first immobility episode. (b) Immobility time during 2 min intervals and the whole 6 min of tested period. Tail suspension test: (c) Latency to the first immobility episode. (d) Immobility time during 6 min of tested period. Data are shown as means±s.e.m., (a, b): n=10, (c, d): n=9. ^***P<0.001, ^**P<0.01, ^*P<0.05 vs Tph2^+/+; ^§§§P<0.001, ^§§P<0.01, ^§P<0.05 vs Tph2^+/−, one-way ANOVA with Bonferroni correction. ANOVA, analysis of variance.
