Dopamine Agonists in Parkinson's Disease Decouple Risk-Taking from Reward-Paired Cues by Enhancing Risky Choice in Their Absence

This study shows that dopamine agonists combined with levodopa increase risky choices in Parkinson's patients even without reward-paired cues.

Cortical morphology predicts long-term placebo response in multiple sclerosis patients

The paper examines how cortical morphology correlates with long-term placebo responses in multiple sclerosis patients, finding that non-responders have a more small-world-like cortical topology and lesion load inversely predicts cortical thickness in specific brain regions.

Dopamine replacement remediates risk aversion in Parkinson’s disease in a value-independent manner

This study shows that dopamine replacement in Parkinson’s disease patients reduces risk aversion in a value-independent manner, while also increasing sensitivity to expected values.

Win-concurrent sensory cues can promote riskier choice

This study investigates how reward-paired sensory cues affect risk-taking behavior in humans, finding they promote riskier choices and increase arousal.
