Neurophysiology of Electroacupuncture Analgesia

  • Richard S. S. Cheng


In recent years, electroacupuncture (EA) analgesia has been the focus of intense multidisciplinary research. This research has been very productive, leading to the publication of numerous studies that have added to our understanding of the neurophysiology of pain perception and pain modulation. This article will review the results of some of these studies, from which the central roles in pain modulation played by the endorphins and various monoamines (serotonin, in particular) will become apparent. In conclusion, an integrated neurophysiological model of EA analgesia will be proposed.
