7) “No man is an island, entire of itself; every man is a piece of the continent, a part of the main; ….” Suppose the main is the social brain, the words written by J. Donne may imply a hint for future trends in neuroimaging. As most social skills, such as learning through imitation, understanding others’ intentions, consist of interpersonal communication, it is difficult to fully understand the neural basis of mental life from a single brain point of view. In this regard, to show the need for simultaneously measuring the interactive activity of two brains within real-life contexts, I will introduce a variety of NIRS experiments including verbal and non-verbal communication conducted in my lab. Finally, I will discuss how face-to-face contexts (e.g., deceiver/lie-detector) entrain coupling of neural activity across two brains to demonstrate how NIRS may be used to investigate hyper scanning of dyadic social interaction.
