Abstract

This paper aims to construct and analyze brain functional network under magnetic stimulation, and further to provide a theoretical basis for exploring the acupuncture mechanism. In this study, magnetic stimulation was used to stimulate acupoint of Neiguan, and EEG signals of three states including pre-, during- and pro-stimulated states were recorded. Using C₀ complexity and mutual information method, the brain functional networks of three states were constructed. And then, using the complex network theory, the topological features of complex network were comparatively analyzed. The experimental results show that the average degree, the average clustering coefficient, the average global efficiency and the small-world property under stimulated state obviously increase, compared with those under the pre-stimulated state. It indicates that magnetic stimulation acupoint of Neiguan improves the channel connection of brain network, the degree of grouping and the efficiency of information transmission obviously. Moreover, the topological features under pro-stimulated state increase in the whole compared with those under the pre-stimulated state, while the topological features under pro-stimulated state present decreasing trends in the whole compared with those under the stimulated state.

Key words： Electroencephalograph signal acupoint of Neiguan C₀ complexity brain functional network
