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.

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

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.

Preservation of eye movements in Parkinson's disease is stimulus and task specific

This study examines oculomotor function in Parkinson's disease patients, finding task- and stimulus-specific preservation of eye movements in response to dynamic targets.

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.

Small effect size leads to reproducibility failure in resting-state fMRI studies

This paper shows that small effect sizes in resting-state fMRI studies lead to reproducibility issues, even after multiple comparison corrections, and recommends meta-analysis of un-thresholded data for better results.
