Brain activity associated with specific words is mirrored between speaker and listener during a conversation

When two people interact, their brain activity becomes synchronized, but it was unclear until now to what extent this 'brain-to-brain coupling' is due to linguistic information or other factors, such as body language or tone of voice. Researchers report that brain-to-brain coupling during conversation can be modeled by considering the words used during that conversation, and the context in which they are used.
