Brief summary

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.
