This study investigates how opioids modulate curiosity-driven exploration in music using a pharmacological paradigm and finds that naltrexone reduces exploratory behavior during high-curiosity states.

This study investigates how dopamine and opioid receptor antagonism affect neural processing of social and non-social rewards using functional neuroimaging and pharmacological interventions.

This study investigates how dopamine D2 and opioid receptor antagonism affects the balance between model-based and model-free behavior in healthy volunteers, finding that D2 antagonism increases model-based behavior while opioid antagonism has no significant effect.

The paper examines how morphine affects cortisol response to stress and links it to changes in negative mood and social reward seeking in humans.

This study investigates the neurochemical basis of hedonic facial reactions to social and nonsocial rewards by manipulating dopaminergic and opioidergic systems in humans.
