Extended Data Fig. 5: Skin conductance responses from patients in study 2.

(A) When the two treatments were administered in the original order, patients’ SCRs were significantly weaker for the thermedol than control treatment. (B) When the two treatments were administered in the reverse order, patients’ SCRs between the two treatment were not significantly different. All panels include data from 30 patients across both orders. Error bars represent S.E.M.
