Aim:To explore the central mechanism of balancing acupuncture by using resting-state functional Magnetic Resonance Imaging(fMRI) with functional connection. Methods; Ten healthy volunteers participated in the experiment. fMRI images were obtained before and 10 minutes after balancing acupuncture. Results; Bilateral middle temporal gyrus, Supraorbital gyrus, head of caudate nucleus, In-sula, left dorsal thalamus, Bilateral superior frontal gyrus, left middle frontal gyrus, anterior cingulate gyrus, right inferior parietal lobule enhance their connection with amygdala after balancing acupuncture. Conclusion:Temporal lobes, frontal lobes, basal ganglion, cingulate gyrus, enhance their connection with amygdala after balancing acupuncture, these brain regions associated with analgesic function.%目的:应用静息态脑功能磁共振成像技术,探讨平衡针的中枢作用机制.方法:选择10名健康志愿者,于针刺平衡针前后分别进行磁共振腩功能成像扫描,应用功能连接方法处理功能磁共振(fMRI)成像数据,针刺前后两组数据采用组间配对t检验统计分析.结果:针刺后的双侧颞中回、双侧眶上同、双侧尾状核头、双侧岛叶、左侧腹背侧核、双侧额上回、左侧额中回、前扣带回、右侧顶下小叶连接增强.结论:针刺平衡针后颞叶、额叶、基底节、扣带回等相关脑区功能连接增强,这些脑区与平衡针的镇痛功能调节作用有关.
