This study examines how varying patellar tendon-tap intensity affects cortical and muscular responses to proprioceptive stimulation, finding increased response strength but no change in variability.

The paper introduces a MEG-compatible stimulator for knee-joint proprioception and shows it reliably elicits cortical responses with good repeatability.

The paper examines how muscle fatigue affects cortical processing of proprioceptive afference and finds no significant change in early processing but notes altered MEG power and alpha/beta activity in sensorimotor cortex.

The paper shows that active finger movements enhance proprioceptive processing in the primary sensorimotor cortex compared to passive movements.

The paper investigates cortico-muscular coupling during steady muscle force maintenance, finding temporally stable beta oscillations and their behavioral relevance.

The paper studies corticokinematic coherence (CKC) during proprioceptive stimulation of the hand to identify cortical processing patterns.

This study shows reduced beta rebound in Parkinson's disease patients during proprioceptive stimulation compared to healthy controls, suggesting impaired cortical processing of proprioceptive feedback independent of dopaminergic effects.
