Optimization of deep brain stimulation parameters in patients with medically refractory epilepsy

This study will develop a platform for stimulation setting optimization based on power spectral density (PSD) measures. Randomized, controlled trials have demonstrated that stimulation of the anterior nucleus of the thalamus (ANT) suppresses seizures. The central hypothesis tested here will be that PSD measured in the ANT will correlate with seizure frequency and stimulation settings that suppress broadband activity will result in lower seizure rates.
