Comparisons of the responses to peripheral noxious mechanical pinch in ACC neurons. (A) The histogram of pinch-evoked responses in individual types (RS; grey, IM; blue and IB; red). (B) The summary of Fig. 5B. Pinch activated all types (*P < 0.05, **P < 0.01, compared with control, one way ANOVA). The pinch-evoked response in IB significantly increased, compared with those in RS and IM (#P < 0.05, ##P < 0.01, one way ANOVA). There were no changes between ipsilateral and contralateral evoked responses in all types.
