Optimal Stimulation Parameters to Disrupt Epileptiform Activity

November 15, 2023 updated by: Catherine Chu, MD, Massachusetts General Hospital

Optimal Stimulation Parameters for Spike-ripple Disruption in Patients Undergoing Invasive Monitoring

Open-loop electrical stimulation has been found to reduce spike activity and seizures, but determining the optimal parameters to achieve these effects requires a brute force trial-and-error approach that relies on subjective physician discretion. We will compare the performance of stimulation parameters identified in rodent models to the recommended parameters for neuromodulation used in clinical practice.
