Experimental setup in turn‐taking verbal interaction using simultaneous EEG/MEG. Verbal communication between subjects was conducted using a condenser microphone and earphones in an online environment. There are three types of tasks: interacting, speaking, and listening. Interacting: counting numbers in turn from 1 to time limit. Speaking: each subject speaks the numbers alone from 1 to time limit without any listening and visual input. Listening: each subject listens to his/her partner's number counting from 1 to time limit without any response. The distance between the two rooms was ∼100 miles.
