• Social interaction is characterized as the emergent product of continuously coupled brain–body systems within and between individuals; hyperscanning studies show inter-brain synchrony during cooperation, conversation, and joint attention.1
  • Physiological synchrony (autonomic signals converging between partners) tracks rapport, cohesion, and cooperative success; interoception provides a conceptual bridge between neural and physiological levels.1
  • Atypical interoceptive processing is implicated in conditions with social difficulties; emerging hyperscanning work is examining interoception-directed effects on neural coupling.1 1

  • An fNIRS hyperscanning study in athletes showed that team type and sex influence interpersonal trust and associated neural mechanisms (Nature). 2
