Moderation Of The Relationship Between Reward Expectancy And Prediction Error-related Ventral Striatal Reactivity By Anhedonia In Unmedicated Major Depressive Disorder: Findings From The Embarc Study
Objective—Anhedonia, disrupted reward processing, is a core symptom of major depressive disorder. Recent findings demonstrate altered reward-related ventral striatal reactivity in depressed individuals, but the extent to which this is specific to anhedonia remains poorly understood. The authors examined the effect of anhedonia on reward expectancy (expected outcome value) and prediction error-(discrepancy between expected and actual outcome) related ventral striatal reactivity, as well as the relationship between these measures.
