≪Organizer Abstract≫
A maxim tells us that "two brains are better than one", but we do not know the scientific answer to that saying. Although cognitive neuroscience research has a wide scope, the experimental paradigms used are primarily concerned with studying the neural correlates of one individual's behavioral processes. Coupled brains can create new phenomena such as cooperation and competition, including verbal and nonverbal communication and interpersonal interaction. Thus, there has been an increasing amount of research that has proposed studying the brains of two interacting people in realistic everyday situations. The purpose of this thematic session is to explore the mechanism of brain-to brain coupling in our daily life.
