Experimental studies on electroacupuncture analgesia (EAA). III. Evoked responses of Motor and Sensory nerves in the chicken under EAA / 全日本鍼灸学会雑誌

After being stimulated by the application of electroacupuncture (EA) to “KOTAN” leg point (bilaterally), chickens became sedated and showed and showed analgesia with little response to skin clamping. Following the observation of M waves of Motor nerves and evoked responses of Sensory nerves, it was found that while efferent information was temporarily inhibited during EA stimulation, afferent information was depressed during EA and the effect continued for several hours after termination of EA. It is suggested that these phenomena may be controled by neurohumoral mechanisms.
