| Outline of Final Research Achievements |
We measured human scalp EEG, and simultaneous fMRI-EEG to investigate the neural mechanisms of communication. In this project, we assumed that the communication, ranging from cortical networks in the brain to social networks between humans, can be explained by a common theoretical framework on the neural oscillations. The results indicated that the dynamic cortical networks in the brain were achieved by a hierarchical synchrony of neural oscillations between the theta and gamma EEGs. The hierarchical synchrony of neural oscillations also enhanced the communication between humans, where the slower oscillation in delta EEG conveyed information represented by the theta EEG in the brain to others. We demonstrated that the underlying mechanism of communication can be described by a common theoretical framework on the neural oscillations ranging from cortical networks in the brain to real human-human interaction.
