| Research Abstract |
Neural synchrony is a crucial mechanism to dynamically communicate between cortices in the brain. The neural synchrony is usually observed as the EEG activity, and has been often elucidated in the term of mnemonic function. We used the scalp EEG recordings during a sentence comprehension task and a vocal communication task, in order to elucidate the underlying mechanism of the verbal communication in the current project. Here we assumed that the neural synchrony is the common mechanism to explain the verbal and non-verbal communications. For investigating the mechanism of non-verbal communication, the causal relationship analysis of fMRI was used to verify the dynamical modulation of the cortical networks caused by non-verbal interaction to others. We also elucidated the mechanism of the inter-personal communication emerges with the neural synchrony of EEGs from two brains.
