Acupuncture inhibition on neuronal activity of spinal dorsal horn induced by noxious colorectal distention in rat

Figure 6 Statistical graph showing the effects of acupuncture on the responses of convergent neurons to CRD in normal and spinalized rats. Open columns represent the CRD induced the neuron’s responses; hatched columns exhibit the effects of acupuncture at the acupoint of non-receptive field on CRD-induced responses before and after reversible spinalization. ^bP<0.001 vs CRD-induced response and acupuncture effect of post-spinalization compared with that of normal animals respectively.
