説明

We propose a framework for understanding the neural underpinning of communication-based processes, using electroencephalogram (EEG) synchronization. The framework comprised four stages: (i) characterization of the target communication in a two-dimensional space defined by symbolic/embodied (non-symbolic) and voluntary/involuntary processes, (ii) a focus on the level of synchronization analysis on an ontological hierarchy, (iii) a construction of a neurocognitive model to explain neural mechanism, and (iv) empirical hypothesis testing of neural underpinning with model-based EEG connectivity neurofeedback processes. We claim that following the framework will advance our understanding of neural dynamics and mechanisms for communication. During this study, we analyzed two EEG experiments, while implementing two former stages: the formation of symbolic communication changing from voluntary to involuntary and embodied communication competing between voluntary and involuntary. Their outcome was a hypothesis that three brain regions were involved in interpreting symbols, motor intentions, and social coordination. Finally, we described the advantages and limitations of the proposed framework, following a discussion concerning its operational validation in the latter stage.
