摘要：

Traditional analyses of event-related potential (ERP) have mainly focused on the components and latency, with few analyses of the connectivity among different functional areas of the brain. The bootstrap and the imaginary part of the coherence can be used to study the brain connectivity. A motion related experiment was designed to analyze the effectiveness of the method. Group statistical analysis was used to show the differences between the connectivities evoked by auditory, visual and movement stimulations. The results show a significant pattern difference of the topographical connectivities between corresponding sensory and motor area, which is consistent with previous studies. This study indicates that the bootstrap and the imaginary part of the coherence can be used to study the connectivities between various brain areas as a complementary tool to traditional ERP studies.
