磁刺激光明穴产生脑组织电信号的变化

中国河北工业大学所在课题组进行关于针刺、电刺激和磁刺激的一项研究,利用磁刺激线圈对正常人体左侧光明穴(GB37)进行重复脉冲磁刺激并观测脑电信号,与非穴位点磁刺激的脑电信号进行对比,并同时对比磁刺激光明穴视觉刺激产生的脑电信号差异。结果显示磁刺激正常人光明穴对脑图电信号影响显著,其机制可能与顶区、中央区和右颞区脑图电信号样本熵值变化显著有关,样本熵值的变化可以有效的区分不同生理状态下的脑图电信号。

Effect of repeated-pulse transcranial magnetic stimulation at the Guangming point on EEGs

In a recent study reported in the Neural Regeneration Research (Vol. 9, No. 5, 2014), repeated-pulse transcranial magnetic stimulation was administered to healthy people at the left Guangming (GB37) and a mock point, and calculated the sample entropy of electroencephalogram signals using nonlinear dynamics. Additionally, researchers compared

electroencephalogram sample entropy of signals in response to visual stimulation before, during, and after repeated-pulse transcranial magnetic stimulation at the Guangming. Results showed that repeated-pulse transcranial magnetic stimulation at the Guangming evokes different patterns of electroencephalogram signals than repeated-pulse transcranial magnetic stimulation at other nearby points on the body surface, and that repeated-pulse transcranial magnetic stimulation at the Guangming is associated with changes in the complexity of visually evoked electroencephalogram signals in parietal regions, central gyrus, and temporal regions.
