00:54 The neuronal basis for acupuncture’s effect on inflammation

In mice, electroacupuncture has been shown to reduce inflammation, but only when certain points on the body are stimulated. Why this is has puzzled scientists, but now, researchers have identified the specific neurons that are involved. They hope that this knowledge could be used in future to help treat certain inflammatory-related diseases.
