Corticobulbar Excitability in Parkinson’s Disease: Evidence from TMS-Evoked Potentials of Submental Muscles

2025-10-01

Abstract excerpt

<p>Background. The corticobulbar (CB) tract links the motor cortex with orofacial muscles and is closely associated with motivational arousal and reward-related processing. In Parkinson’s disease (PD), where dopaminergic dysfunction is a core feature, alterations in corticobulbar excitability may provide insights into both motor and motivational deficits. Objective. This study investigated whether motor evoked pot...
