Figure 12. The effect of MONNA on CQ‐induced action potential discharge and bouts of scratching.

A, the mean ± SEM of CQ in the absence and presence of MONNA (10 μm, 15 min), in 10 CQ‐sensitive C‐fibres (* P < 0.05). B, the means ± SEM of the number of bouts of scratching over 30 min in the presence of CQ (10 mm; n = 7) or CQ + MONNA (1 mm; n = 5) (* P < 0.01).
