The results of the SI test after the 10-day chronic social defeat stress procedure. (A) Mouse track examples in the SI behaviour test. (B) Time spent in the interaction zone for control (n = 10), susceptible (n = 31), and resilient (n = 6) mice. The susceptible mice spent less time in the interaction zone when CD-1 mouse was present than when CD1 was absent. **P = 0.000 (Target vs. No target) for susceptible mice, by two-tailed t-test. (C) The control (n = 10), susceptible (n = 31) and resilient (n = 6) mice were divided according to their SI ratio. **P = 0.001 (susceptible vs. control); **P = 0.002 (resilient vs. control); **P = 0.000 (resilient vs. susceptible), by one-way ANOVA, followed by post hoc least significant difference test. All data are represented as mean ± SEM, *P < 0.05 and **P < 0.01.
