Conventional RSDS produces social avoidance in a small fraction of female mice. (A) Experimental schematics of conventional RSDS applied to female C57BL/6J mice. (B) Social interaction (SI) testing apparatus depicting the interaction zone (pink) and corner zone (blue) (top). Representative traces of the exploratory behavior of control and susceptible female mice in the presence and absence of a novel male mouse (bottom). (C) Distribution of SI ratio in control and defeated females. Defeated females that showed social avoidance (SI ratio <1) were categorized as susceptible, and females that showed social preference (SI ratio ≥1) were categorized as resilient. (D) Time spent in the interaction zone and corner zone and (E) locomotor activity when the social target was present in the arena. C: control, S: susceptible, R: resilient. Data represent mean ± SEM. Number of animals is indicated in parentheses. *p < 0.05; **p < 0.01; ***p < 0.001 in Tukey’s post hoc test after One-way ANOVA.
