The paper investigates how social closeness and individual differences in reward sensitivity and substance use affect ventral striatal activation and connectivity during shared reward experiences.

The paper investigates how neural responses to betrayal and unfairness are linked through insula-valuation network dynamics in social exchange tasks.

The paper investigates how the cerebellum and ventral striatum process social rewards using fMRI, finding the cerebellum responds uniformly to feedback regardless of reward valence, unlike the striatum.

This study examines how trait reward sensitivity influences neural connectivity patterns during strategic decision-making tasks using fMRI.

The paper examines how reward sensitivity and subclinical substance use relate to striatal function during social rewards, finding nuanced neural correlates linked to potential risk for substance use disorder.
