EEG COHERENCE ANALYSIS BASED ON MVAR MODELING AND ITSAPPLICATION IN THE STUDY OF THE COORDINATION OF BRAIN AREAS
基于多变量AR模型的脑电相干性分析及其在脑区协作机制研究中的应用

The mechanism of functional coordination between different cortical area of human brain is an important problem for the brain cognitive research and the neuroscience. The dynamic coherence analysis based on multivariate autoregressive (MVAR) modeling was applied in the observation of synchronization between brain areas during cognitive processing. The result indicates that the synchronization of relative brain areas happens automatically despite the distractive stimulus during object perceiving, but the disturbed attention affects the synchronization of those areas involved in the judgement and voluntary movement as the way it affects the reaction time.
