Cerebral cortex functional networks of magnetic stimulation at acupoints along the pericardium meridian
The coordinated regulating mechanism of magnetic stimulation at acupoints along the pericardium meridian was studied by cerebral cortical functional networks. Electroencephalogram signals of 14 subjects (eight males and six females) were recorded in resting state and following magnetic stimulation a...

The coordinated regulating mechanism of magnetic stimulation at acupoints along the pericardium meridian was studied by cerebral cortical functional networks. Electroencephalogram signals of 14 subjects (eight males and six females) were recorded in resting state and following magnetic stimulation at Neiguan and Daling acupoints along the pericardium meridian. The corresponding cortical functional networks were constructed and analyzed by group independent component analysis, standard low-resolution brain electromagnetic tomography, short-time Fourier transform, and complex network theory. Results showed that during magnetic stimulation at Daling and Neiguan acupoints, the functional connections of the nodes in the brain areas associated with movement respectively decreased by 7.3% and 19.9%, and the functional connections of the nodes in brain areas associated with advanced cognitive functions such as emotion, memory and language respectively increased by 24.9% and 18.8%. Changes of topological structure were similarly related to the efficacy of acupoints along the pericardium meridian. Magnetic stimulation also caused different topological changes consistent with the therapeutic function of specific acupoint. This study provided new evidence revealing mechanisms of brain functional integration and network synergy in the acupoint stimulation pathway. |
