Differential modulation of STN-cortical and cortico-muscular coherence by movement and levodopa in Parkinson's disease

► Administration of levodopa reduced M1-STN beta coherence. ► Repetitive movement reduced alpha and beta M1-muscular coherence. ► STN but not muscle coherent to superior temporal gyrus in alpha band ► M1-STN and M1-muscular beta coherence anti-correlated with akinesia in OFF state
