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

The paper investigates how subthalamic nucleus neurons encode phoneme and sequence features of speech in Parkinson's patients during deep brain stimulation.

The paper analyzes aperiodic components of local field potentials in cortical and subcortical regions, finding differences in aperiodic exponents and the absence of aperiodic knees in subcortical areas.

This study identifies hyperdirect connectivity between opercular speech regions and the subthalamic nucleus in humans using intracranial recordings during deep brain stimulation.

The paper identifies speech-induced artifacts in intracranial recordings and shows they correlate with speech audio and vibration patterns.

This paper compares electrocorticography (ECoG) and subthalamic local field potentials (LFP) for movement decoding in Parkinson's disease, finding ECoG superior and demonstrating the impact of PD pathophysiology on decoding performance.

The paper investigates thalamic activity during reading aloud, finding lateralized gamma activity related to lexical status processing.

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.

The paper examines high gamma activity in the subthalamic nucleus and sensorimotor cortex during speech production, finding articulator-specific signals in both regions with similar timing but different topographical organization.

The paper examines subthalamic nucleus neuron activity during speech production, finding distinct firing rate changes related to speech planning and execution.

This study examines STN activity and subthalamic-cortical dynamics during force generation, finding that STN gamma activity predicts cortical activity and contributes to motor planning and execution.
