Summary

This study used brain imaging (fMRI) to see how heavy drinkers' brains respond to pictures of alcohol versus non-alcoholic drinks. 72 non-treatment-seeking heavy drinkers made hypothetical decisions about buying alcohol at different prices while in the scanner. The goal was to understand how alcohol-related cues change the perceived value of drinking, which could inform future addiction treatments.
