Post-intervention high-beta synchronization tracks stable-manifold alignment during stick-balancing learning

This study shows that post-intervention high-beta EEG synchronization correlates with the quality of transitioning from active correction to intrinsic dynamics during stick-balancing learning.

Embodied Emergence of Temporal Complexity in Finger Tapping: Synaptic and Dopaminergic Control in Cortico-Basal Ganglia Loops

This paper presents a computational model of finger tapping that shows how temporal complexity arises from neural and physical interactions, and how dopamine depletion disrupts this complexity, mimicking Parkinson's disease features.

Neural mechanisms of postural sway-related beta-band oscillations: a cortico-basal ganglia-thalamic network model of intermittent control

This paper develops a computational model of the cortico-basal ganglia-thalamic network to explain beta-band oscillations during postural sway, showing they emerge from intermittent control mechanisms.

A Dynamical Digital Twin Unmasks Hidden Neuromotor Control Policies and Catastrophic Tipping Points in Parkinson's Disease

The paper develops a dynamical digital twin framework to uncover hidden neural control policies and catastrophic tipping points in Parkinson's disease by analyzing sway kinematics and Bayesian inference.

Discrete cortical control during quiet stance revealed by desynchronization and rebound of beta oscillations

The paper identifies discrete cortical control during quiet stance through beta oscillation desynchronization and rebound, supporting an intermittent control model over continuous stiffness control.

Preferential activation of proprioceptive and cutaneous sensory fibers compared to motor fibers during cervical transcutaneous spinal cord stimulation: A computational study

This study uses a computational model to show that cervical tSCS preferentially activates sensory fibers over motor fibers, suggesting high proprioceptive and cutaneous contributions to neural activation.

Long-lasting event-related beta synchronizations of electroencephalographic activity in response to support-surface perturbations during upright stance

The paper investigates beta rebound in EEG during postural recovery from support-surface perturbations, finding it lasts up to three seconds and occurs before motion recovery.
