-
To observe the regional homogeneity (ReHo) of resting-state brain function in the healthy subjects of gastric distention treated with acupuncture at the back-shu and front-mu points of the stomach, Weishu (BL 21) and Zhongwan (CV 12) and the correlation with gastric motility so as to explore the mechanism on the central integration of the front-mu and back-shu points of the stomach. ⋯ Acupuncture at the combined back-shu and front-mu points of the stomach, as well as acupuncture at single Weishu (BL 21) and Zhongwan (CV 12) induce the ReHo changes in the different brain regions. Acupuncture at the combined back-shu and front-mu points of the stomach may induce the ReHo changes in some new brain regions as compared with the acupuncture at the single point. The thalamus, the posterior cingulate gyrus and the precuneus may be the the important integrated brain regions for acupuncture at the back-shu and the front-mu points in regulating the gastric motility. The effects of acupuncture at the back-shu and the front-mu points for the regulation of the gastric motility are closely related to the thalamus, the limbic system and the default network of the brain regions.
