Abstract

Objectives and Methods : This study was performed to investigate the effect of electro -acupuncture at four gates(bilateral LR3 and LI4) on brain activity in normal subjects using fMRI. Results and Conclusions : 1. fMRI signal increase by electro-acupuncture at Lt. LR3 was observed in Rt. Middle frontal gyrus in group average as well as more than half of the subjects. 2. fMRI signal decreases by electro-acupuncture at Lt. LR3 were observed in Rt. Superior frontal gyrus, Rt. Middle temporal gyrus, Rt. Cingulate gyrus in group average as well as more than half of the subjects. 3. fMRI signal increases by electro-acupuncture at Lt. LI4 were observed in Lt. Superior frontal gyrus, Lt. Middle frontal gyrus, Lt. Inf. Semi-Lunar Lobule(cerebellum), Rt. Middle frontal gyrus, Rt. Cingulate gyrus in group average as well as more than half of the subjects. 4. fMRI signal decreases by electro-acupuncture at Lt. LI4 were observed in Lt. Middle frontal gyrus, Lt. Inferior frontal gyrus, Lt. Precentral gyrus and Rt. Middle frontal gyrus, Rt. Middle temporal gyrus, Rt. Precuneus, Rt. Inferior frontal gyrus, Rt. Postcentral gyrus in group average as well as more than half of the subjects. 5. fMRI signal increase by electro-acupuncture at Lt. LR3 and Lt. LI4 in group average as well as more than half of the subjects was not observed. 6. fMRI signal decreases by electro-acupuncture at Lt. LR3 and Lt. LI4 were observed in Lt. culmen(cerebellum), Lt. Cingulate gyrus와 Rt. Middle frontal gyrus, Rt. Cingulate gyrus, Rt. Inferior frontal gyrus in group average as well as more than half of the subjects. 7. fMRI signal increases by electro-acupuncture at four gates (bilateral LR3 and LI4) were observed in Lt. Middle temporal gyrus and Lt. Postcentral gyrus in group average as well as more than half of the subjects. 8. fMRI signal decrease by electro-acupuncture at four gates (bilateral LR3 and LI4) were observed in Lt. Middle frontal gyrus, Lt. Precentral gyrus, Lt. Inferior frontal gyrus, Lt. Middle temporal gyrus, Lt. Frontal sub-gyral and Rt. Tuber(cerebellum) in group average as well as more than half of the subjects.
