[Abstract] Objective: To compare the difference of regional homogeneity (ReHo) between post-acupuncture and electro-acupuncture stimulation with pre-acupuncture at Baihui acupoint. And to explore the immediate changes of blood oxygenation level dependent functional magnetic resonance imaging (BOLD-fMRI) by electro-acupuncture at Baihui acupoint.Materials and Methods: 20 healthy subjects were selected. After acupuncture and"de qi", connected with the electro-acupuncture stimulator. The scanning was carried out at 3.0 T MRI. Using the flexible head coil, BOLD-fMRI scanning was performed before injection, after injection and during electrical stimulation. The data were processed by RESTplus, and the results were tested by paired t-test.Results: After acupuncture, compared with pre-acupuncture, the brain area with higher ReHo value were left postcentral gyrus and right precentral gyrus, and the brain area with lower ReHo value were bilateral middle temporal gyrus and cerebellum. When the Baihui acupoint was stimulating by electro-acupuncture, compared with pre-acupuncture, the brain area with higher ReHo value were bilateral postcentral gyrus, bilateral precentral gyrus, right superior temporal gyrus, bilateral lingual gyrus, right insular, left calcarine, and the brain area with lower ReHo value were bilateral precuneus and cerebellum.Conclusions: In this study, we obtained the change of ReHo value of "Deqi" state by acupuncture at Baihui acupoint, and which immediately during the electro-acupuncture stimulation. Which proved a feasible method to study the immediate brain effect of head acupoint electro-acupuncture by using the head flexible coil and supporting device.
