ABSTRACT: Through the treatment of 65 cases of painful diseases with electroacupuncture, in comparing with the analgesic effect of contralateral stimulation (CS) and ipsilateral stimulation (IS), it was verified that IS and CS had the similar effect on pain-relieving, while CS was better in improving motor impairment. By testing the rat's pain threshold and recording the neuronal activity in the D-PAG, it was found that neither IS nor CS could increase the pain threshold in the unilateral D-PAG lesioned rats, and the excited neuronal discharge was recorded in the unilateral D-PAG by stimulating rat's Zusanli (ST 36) at each side. It indicates that IS and CS might share the same high level afferent pathway in acupuncture analgesia in CNS.
