Abstract
Pain is one of the most important sensations in daily life,andthe traditional Chinese medicine such as acupuncture has shown great potential in pain relief. The principle research of acupuncture anesthesia has been the focus of modern science. In this paper the noninvasive brain imaging technique fMRI (functional magnetic resonanceimaging) was used. Eight volunteers were enrolled and received pain stimulation,andthe brain response under TEAS (transcutaneous elec-trical acupoint stimulation) and manual needle stimulation were observed. The research finds pain has specific sensation region and the acupuncture anesthesia is realized through modulating the corresponding brain function region, but the manual needle has wider brain response region than TEAS.

Acupuncture pattern: 1) Manual needle stimulation, which was operated by my professional doctor; 2) TEAS stimulation: Transcutaneous electric acupoint stimulation (HANS: Han’s acupoint nerve stimulator, Model LH202H TEAS) was used
Summary
Pain is one of the most important sensations in daily life. Pain perception is much more complicated than any other human perceptions. The research of mechanism of acupuncture analgesia has become more and more important. Nical in acupuncture treatment has become the research focus in recent years, especially the various noninvasive brain imaging technologies and their application in illustrating the cerebral mechanism of acupuncture anesthesia. It is a huge progress in revealing the scientific essence of acupuncture therapy effect [5,6,7,8]. The paper applies Functional Magnetic Resonance Imaging to study brain activity changes in the different stimulation modes in LI. (Hegu acupoint). From a new aspect to discusses the analgesic effect in different acupuncture stimulation modes, to provide the visible and objective criterion for clinical application of acupuncture analgesia
