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

Figure 4 Statistical graph showing the effects of acupuncture and pinch on the responses of convergent neurons to CRD. Control CRD: CRD induced the neuron’s responses; CRD+Pinch NRF: effect of pinch in non-receptive field on the responses of the neurons to CRD; CRD+Pinch RF: effect of pinch in the receptive field; CRD+Acup. NRF: effect of acupuncture in non-receptive field; CRD+Acup. RF: effect of acupuncture in receptive field. ^bP<0.01 and ^dP<0.001 vs Control CRD respectively.
