Social closeness and reward sensitivity enhance corticostriatal function during experiences of shared rewards

Key Points

• Enhanced reward sensitivity is significantly associated with improved corticostriatal function during shared rewards.
• Participants demonstrating high social closeness showed notable increases in dopaminergic pathways activation.
• This analysis involved direct measurements of brain activity using neuroimaging techniques in diverse social contexts.
• These findings suggest that fostering social relationships may promote better reward processing in everyday life.
