A06: Decoding dynamic reciprocal neural mechanism underlying reactive aggression: Insights from fMRI and fNIRS hyperscanning

The project employs fMRI and functional near-infrared spectroscopy (fNIRS) hyperscanning techniques to explore how brain-to-brain synchrony and dynamic processes within peer dyads facilitate or inhibit aggressive behavior under diverse levels of provocation in adolescent patients and controls. In two fully interactive tasks, we will probe aggressive behavior towards a task partner, and quantify the building of interpersonal trust/distrust applying a social interaction and economic exchange paradigm. These paradigms will be employed within dyads in fMRI hyperscanning settings and extended by group-based fNIRS methods in triads to study effects of peers, social exclusion, and coalitions on aggressive behavior in semi-naturalistic interactions. Between-brain neural synchrony will be computed and related to everyday social experiences and individual predispositions to identify markers for the prediction of aggressive behavior.
