Neural oscillations and phase-amplitude coupling in Parkinson’s disease

November 9, 2017

Oscillatory neural activity in different frequency bands and phase-amplitude coupling (PAC) are hypothesized to be biomarkers of Parkinson’s disease (PD). Might these activity features help explain PD motor dysfunction, and serve as viable targets for closed-loop deep brain stimulation (DBS)? In this podcast, Editor-in-Chief Bill Yates (University of Pittsburgh) talks with David Escobar Sanabria (Department of Neurology, University of Minnesota) and Luke Johnson (Department of Neurology, University of Minnesota) about a recent study which explored these questions. Their findings helped to characterize these biomarkers across various vigilance states, and to build a foundation for future therapeutic techniques.
