OBJECTIVE: To observe the signal changes of brain functional area during
needling Sanyinjiao (ST36), Zusanli (SP6) and Yanglingquan (GB34), the three
acupoints in three different meridians, in human by functional magnetic
resonance imaging (fMRI), in order to preliminary explore the neural
mechanism of acupuncture. METHODS: Needling was complemented with 30 s of
maneuver applying followed by 30 s of rest as a circle on an acupoint, and
at the same time, fMRI was performed once 5 min and 12 s. Then the same
program was repeated with the same mode on another acupoint, until ending
the experiment. RESULTS: The commonly activated regions were postcentral
gyrus and right inferior frontal gyrus when needling at ST36 and SP6, and
the different activated areas included left inferior frontal gyrus, left
insula, left inferior parietal lobule, left culmen, left middle temporal
gyrus and left middle frontal gyrus, while no cortical signal enhanced
region was found when needling at GB34. Signal weakened regions could be
found when needling at all the three points, the commonly activated regions
were bilateral parahippocampal, hippocampal, callosal gyrus, bilateral
praecuneus and cerebellum. CONCLUSION: Brain response in special regions
could be obtained by needling at different acupoints.
