| Research Abstract |
We hypothesized that the transition between synchronization and desynchronization among heterogeneous neuronal and behavioral systems should underlie on the neural principle of the cognitive control. To elucidate this hypothesis, we conducted human EEG measurements and analyses based on dynamical system theory. We found that EEG synchronization/desynchronization in multiple space-time scales in the brain and behaviors can yield predictive indices of cognitive functions, such as working memory capacity, motivation and subjective preference. In two person experiments, an EEG synchronization index was found to represent smooth communication. In conclusion, these results support our working hypothesis.
