Abstract Recently, the research and application on the combination of transcranial magnetic stimulation(TMS) and acupoint stimulation by traditional Chinese medicine has made some progress, graph theory has also been explored in the field of brain research. The combination of these theories and techniques will bring outa new direction for the application of neural magnetic stimulation and research of brain science. In this paper, the linear time domain correlation analysis of EEG between two channels of the magnetic stimulation at Guangming point and the mock point were carried out, each channel of the diencephalon electric data related to the number and the form of correlation matrix was determined by setting the size threshold for obtaining adjacency matrix. The brain functional network was constructed by the signals of the two experimental states. Results showed that the brain function of the laser beam was significantly increased than that of the occipital lobe (visual contact area) and the frontal area. Based on the graph theory, complex network theory was used to compare the parameters of the characteristic parameters of the brain function network.Magnetic acupuncture point laser made the brain functional network changed, the average degree of network and clustering coefficient were increased, and the characteristic path length decreased; meanwhile, the global efficiency and local efficiencywere improved, the property of small world was enhanced, all of which were statistically different.This work provided a theoretical basis for the application of magnetic stimulation technology in improving the nerve function of acupoints.

Key words： magnetic stimulation acupoint electroencephalogram (EEG) brain function network cross correlation
