Neural mechanisms in acupuncture analgesia

The summary of the nervous levels implicated in analgesia in general helps one to understand that the acupuncture analgesia is not simply a psychological or sociological matter as some said when it first appeared. Its mechanisms are the same as the ones existing in other antalgic therapeutics whether nervous or humoral. Not everything has been explained in the action of acupuncture but acupuncture opens new ways to us in the practical field of controlling pain as well as in the theoretical field of pain, the major problem of all the medicines.
