(A) Timeline of social transfer of pain protocol. (B) Timecourse of mechanical von Frey (VF) sensitivity at 0, 4, 24 and 48 h post 1h social interaction in Con/Con and CFA/BY pairs. (C) Mechanical thresholds immediately after the 1 h social interaction. (D) Mechanical thresholds of the ipsilateral vs. contralateral hindpaws. (E) Tail withdrawal latencies in the tail immersion test. (F) Time (%) spent on the warm floor (40° C) in the thermal place test (TPT). (G) Time (s) a stranger conspecific spent sniffing each group. Data are means ± s.e.m. Dotted lines (---) represents mean baseline thresholds for all groups (B, C, D); Statistical tests included two-way repeated measures (A), one-way (B, E, F, G) and two-way (D) ANOVA with Holm-Sidak post hoc tests; *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001 representative of post hoc comparisons. All statistical measure details are presented in Table S1A.
