Meshed chambers enhance social interactions as compared to grooved chambers. a Plot of mean investigation time (measured within 20-s bins) across the SP session for male mice (n = 45) using meshed chambers. b, c Distribution of time dedicated for investigating social (b) and object (c) stimuli during SP experiments with grooved (n = 33) and meshed (n = 45) chambers, according to bout duration (post hoc t test following interaction, MM-ANOVA). d, e Distribution of the number of intervals between repeated investigations of social (d) and object (e) stimuli during SP experiments with grooved and meshed chambers, according to interval duration (post hoc t test following interaction, MM-ANOVA). ***p < 0.001, *p < 0.05
