[Abstract] Objective: To discuss the relation between brain activity and de qi sensation with manual acupuncture.Materials and Methods: Manual acupuncture and superficial tactile stimulations were successively performed on 13 right handed healthy volunteers. Brain mappings were obtained with BOLD-based fMRI technique, and the brain regions activated during two stimulations were analyzed.Results: During manual acupuncture, all volunteers developed different de qi sensation, and the brain activity was individual different correspondingly. The activity of anterior frontal region, thalamus, Corpus striatum, Posterior cingulate cortex, and insula induced by acupuncture at acupoint LI4 (Hegu) had the trend of increasing with acupuncture intensities.Conclusion: There are some relationship between acupuncture intensities (de qi sensation) and brain activity evoked by acupuncture.
