The Cortical Evoked Potential Corresponds with Deep Brain Stimulation Efficacy in Rats

In this podcast senior author Prof. Warren Grill of Duke University discusses his published manuscript "The cortical evoked potential corresponds with deep brain stimulation efficacy in rats" with Editor in Chief Prof. Nino Ramirez. In this paper the authors characterize a new potential biomarker for deep brain stimulation (DBS), the cortical evoked potential (cEP), and demonstrate that it exhibits a robust correlation with motor behaviors as a function of stimulation frequency. The cEP may thus be a useful clinical biomarker for changes in motor behavior. This work also provides insight into the cortical mechanisms of DBS, suggesting that motor behaviors are strongly affected by the rate of antidromic spike failure during DBS.
