Our brains synchronize during a conversation

The rhythms of brainwaves between two people taking part in a conversation begin to match each other. This is the conclusion of a study published in the magazine Scientific Reports, led by the Basque research centre BCBL. According to scientists, this interbrain synchrony may be a key factor in understanding language and interpersonal communication.

Until now, most traditional research had suggested the hypothesis that the brain "synchronizes" according to what is heard, and correspondingly adjusts its rhythms to auditory stimuli.

Now, the experts from this Donostia-based research centre have gone a step further and simultaneously analysed the complex neuronal activity of two strangers who hold a dialogue for the first time.
