Fig 1. Strains exhibit divergent behavioral responses to mechanical stimuli at baseline.

Compared to C57BL/6J mice, 129S6, and CXB7/ByJ mice exhibit differences in (A) paw withdrawal threshold, (B) the number of responses to repeated presentation of a noxious mechanical stimulus sensitivity, and (C) the number of responses to continuous thermal heat. N = 15-16/group. Data expressed as mean ± SEM. ***p<0.001, **p<0.01, *p<0.05 different from C57BL/6J. ^### p<0.001 different from 129S6.
