Researchers at the University of York and the Hull York Medical School in the United Kingdom have found that acupuncture has a significant effect on specific nerve structures.
Quote: "This new study, which was published in Brain Research, indicates that acupuncture has a significant impact on specific neural structures. The study’s authors note that when patients undergo acupuncture treatment, a sensation called deqi can be achieved. An analysis of this response shows that it deactivates areas in the brain that are involved in the processing of pain. Therefore, says Dr. Hugh MacPherson, of the Complementary Medicine Research Group in the University’s Department of Health Sciences, they now have “objective scientific evidence that acupuncture has specific effects within the brain,” and this knowledge will hopefully help researchers better understand how acupuncture works."
But we already knew that, right?
