%X 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.
