The paper identifies body-segment coordination as a predictor of postoperative freezing of gait severity in Parkinson's disease patients using kinematic data and LASSO regression.

This study identifies distinct roles of the cuneiform and pedunculopontine nuclei in gait initiation and freezing of gait in Parkinson's disease using local field potentials and biomechanical markers.

This study shows that beta power reflects motor flexibility rather than vigor, as reducing beta power improved task performance across different motor tasks.

This study identifies distinct STN activity patterns associated with FOG predisposition and occurrence in PD patients, highlighting differences in beta band activity across STN regions.

This study examines how feedback transparency in neurofeedback affects performance and agency, finding that transparent feedback improves performance while motor illusions reduce it.

This study examines inhibitory control during gait initiation using EEG, finding that uncertainty delays reaction time and modulates ERP and time-frequency activities.

This study shows that subthalamic deep brain stimulation and chronic dopaminergic therapy increase free-choice preference in Parkinson's disease patients, with STN-DBS affecting the right medial prefrontal cortex-STN network and chronic dopamine levels enhancing sensitivity to intrinsic rewards.

This study shows that humans prefer choices even when they don't affect outcomes, driven by a need for personal control rather than rewards or exploration.
