Beyond beta rhythms: Aperiodic broadband power reflects Parkinson's disease severity - a multicenter study

This study shows that aperiodic broadband power, not just beta oscillations, is linked to Parkinson's disease severity and is increased in the more affected hemisphere.

The role of STN beta oscillations on lower extremity muscle activity in Parkinsonian stepping

This study examines how STN beta oscillations relate to lower limb muscle activity during stepping in Parkinson's patients, finding distinct beta patterns and levodopa effects on motor control.

Evoked resonant neural activity outperforms spectral markers in decoding sleep from the subthalamic nucleus

This study compares evoked resonant neural activity (ERNA) to spectral markers in decoding sleep stages from subthalamic nucleus recordings in Parkinson's patients, finding ERNA provides better classification accuracy.

The aperiodic exponent of subthalamic field potentials reflects excitation/inhibition balance in Parkinsonism: a cross-species study in vivo

This study investigates the aperiodic exponent of subthalamic field potentials in Parkinsonism across species, finding it reflects excitation/inhibition balance and could be a biomarker for adaptive deep brain stimulation.

Neurofeedback linked suppression of subthalamic beta oscillations speeds up movement initialisation in Parkinsonian Patients

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

Basal ganglia high-frequency activity is co-modulated with the phase of motor cortical beta and shifted between the subthalamic nucleus and the internal pallidum during sustained motor 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.
