Changes in Responses of Neurons in Spinal and Medullary Subnucleus Reticularis Dorsalis to Acupoint Stimulation in Rats with Visceral Hyperalgesia

Figure 3

Responses of WDR neurons to EA at different intensities ((a) 1.5 mA, (b) 6 mA) before and after CRD. Upper rows show original unit discharges and lower rows show histograms. BG shows spontaneous activities. EA pre-CRD shows neuronal activities induced by EA before CRD. EA post-CRD shows neuronal activities induced by EA after CRD stimuli.
