Summary

This study looks at how blocking the brain's opioid system with a drug called naltrexone changes feelings of social connection and brain activity. Healthy adults take either naltrexone or a placebo for a week, report daily social feelings, and undergo brain scans. The goal is to understand the role of opioids in social experiences, not to treat any disease.
