Stimulation of the Anterior Nucleus of the Thalamus for Epilepsy - Recruitment Rhythm (SANTE RR)

The primary objective is to demonstrate that a higher proportion of responders to deep brain stimulation (DBS) in the anterior nucleus (AN) of the thalamus in refractory epilepsy patients in the SANTE study exhibit a recruitment rhythm relative to non-responders.

• Patient or legal representative is able to understand and provide signed consent for participating in the study
