Our brains sync when we converse with each other

London: Having a conversation may cause the brainwaves of two people to synchronise, a study has found. Researchers from Basque Centre on Cognition, Brain and Language (BCBL) in Spain analysed the complex neuronal activity of two strangers who held a conversation for the first time.

By recording cerebral electrical activity the team found that the neuronal activity of two people involved in an act of communication "synchronise" in order to allow for a "connection" between both subjects. "It involves interbrain communion that goes beyond language itself and may constitute a key factor in interpersonal relations and the understanding of language," said Jon Andoni Dunabeitia from BCBL.

Thus, the rhythms of the brain waves corresponding to the speaker and the listener adjust according to the physical properties of the sound of the verbal messages expressed in a conversation.

This creates a connection between the two brains, which begin to work together towards a common goal: communication, researchers said.
