What resolves this contention: Disagreement on whether attenuation of beta-band synchronization is required for clinical motor improvement during DBS — direct test under 60 Hz vs. correlative pallidal-burst comparison. / 60-Hz STN-DBS improves bradykinesia despite amplifying alpha/low-beta oscillatory power, indicating beta-suppression is not necessary for motor benefit. / Prolonged pallidal beta bursts are a disease-specific biomarker for PD-OFF, supporting the view that beta synchronization drives parkinsonian motor signs.
