Abstract: [Objective]To observe the cerebral activating effects of needling in Yanglingquan (GB34) vs a sham point of healthy volunteers based on the technique of fMRI.[Methods]Sixteen healthy volunteers were randomly divided into GB34 group and sham point group,and received needling in the different points on the right side respectfully.Super nuclear magnetic resonance (1.5T,GE Co.) was used to scan the brain and the obtained experimental data of the regional brain were processed and analyzed by method of Region of Interest (ROI).[Results]There was not any difference between needling in GB34 and the sham point in the cerebral activating rate.While the activating number of needling in the sham point was more than that of needling in GB34 in bilateral parietal lobes and right occipital lobe(P<0.05),and the activating strength of needling in the sham point was stronger than that of needling in GB34 in left cerebellum(P<0.05).[Conclusion]Needling in GB34 and the sham point had a certain degree of difference in the activation of cerebral functional regions.
