Dopamine and Opioid Receptor Antagonists Reduce Cue-induced Reward Responding and Reward Impulsivity
RandomizedParallel-groupDouble-blind
Summary
The purpose of this study is to determine how the dopamine and opioid system is involved in reward processing, specifically in cue-induced reward responding and reward impulsivity, using dopamine and opioid receptor antagonists in healthy participants. The investigators predict that particularly the dopamine challenge should alter cue-induced reward responding and reward impulsivity. Such effects would be of high interest for the treatment of disorders which involve impairments of reward processing such as addiction.
