Interpersonal communication is the foundation of human society. Efficient communication allows us to collaborate, transmit experience to each other, and accumulate knowledge across generations. Some even argue that it plays a critical role in the emergence of consciousness.

My researches focus on human communication. Measuring brain signals using fMRI and EEG in naturalistic experimental settings,  I investigate (1) the neural mechanism underlying the hierarchical construction of messages as complex as narratives, (2) the dynamic multi-brain neural network during communication, and (3) how effective communication changes the neural dynamics of the audience and their behaviors. Below are three corresponding findings:

(1) Diverging storylines: unique brain activation patterns for two different storylines are found to grow more and more distinctive from each other while the story unfolds.

(2) Herding effect: like a group of sheep guided by a shepherd, at moments of the speech where the listeners follow the speaker closely, i.e. higher  speaker-listener neural coupling, they also cluster more tightly together, i.e. higher listener-listener coupling.

(3) Information flow: each narrative evokes unique brain activation patterns that propagate from the sensory areas, followed by the language areas, the attention network, and lastly the default mode network.
