This study examines beta oscillations in Parkinson's disease patients during movement direction reversals, finding context-dependent changes in subthalamo-cortical synchronization and beta power modulations.

The paper shows that spike-phase coupling between subthalamic nucleus neurons and posterior opercular cortex predicts speech sound accuracy during speech production.

This study examines how auditory cues affect STN oscillatory activity during stepping in Parkinson's disease, finding differential modulation of beta and transient oscillations.

This study shows that PPN LFP alpha and beta oscillations are rhythmically modulated by gait phase, with spatial specificity and increased modulation in regular stepping.

This study shows that neurofeedback training reduces STN beta bursts and improves movement speed in Parkinson's patients.

This study shows that alternating subthalamic nucleus deep brain stimulation can entrain stepping rhythms in Parkinson's patients, suggesting the STN's role in step timing control.

The paper investigates how high-frequency activity in the basal ganglia co-varies with motor cortical beta oscillations during motor control and rest in Parkinson's patients.

The paper examines cortico-basal-ganglia communication in Parkinson's patients, finding that gamma phase coupling between STN spikes and cortical activity precedes fast reaction times and is modulated by movement direction.
