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

Katherine Muksuris, Ellen Flynn, Tanya L. Feng, Pratibha Surathi, Shanna C. Yeung, Leili Mortazavi, Anna Isberg, Martin J. McKeown, Silke Appel‐Cresswell, Catharine A. Winstanley, A. Jon Stoessl, Jason J.S. Barton, Mariya V. Cherkasova

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

EEG Dynamical Features during Variable-Intensity Cycling Exercise in Parkinson's Disease

Zahra Alizadeh, Emad Arasteh, Maryam S. Mirian, Matthew Sacheli, Danielle Murray, Silke Appel‐Cresswell, Martin J. McKeown

This study uses EEG to identify neural markers correlating with exercise intensity in Parkinson's disease patients, finding reduced inter-subject variability in their responses compared to healthy controls.

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

Mariya V. Cherkasova, Jeffrey C. Corrow, Alisdair Taylor, Shanna C. Yeung, Jacob L. Stubbs, Martin J. McKeown, Silke Appel‐Cresswell, A. Jon Stoessl, Jason J.S. Barton

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.
