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

Figure 2

The response patterns of WDR neurons to different stimuli applied at skin receptive fields and viscera. The whole recording time was 40 s, of which the first 5 s was the duration for recording spontaneous background (BG) discharges; from the 5th to 35th s, the stimuli of touch, bristle, 80 mmHg CRD, pinch, and acupuncture were consecutively administered; the poststimuli BG discharges were recorded from the 35th to 40th s.
