Figure 1From: Expression genetics identifies spinal mechanisms supporting formalin late phase behaviors Formalin-induced nocifensive behaviors. Video recordings of mice licking/biting after plantar hind paw injection of formalin were reviewed for 17 strains of inbred mice (n = 10-25/strain). Bars represent the mean ± S.E.M. percentage of samples featuring licking/biting in early (0-5 min; graph A) and late phase (10-60 min; graph B).Back to article page
