What this trial studies

This observational study focuses on understanding the physiological and pathological brain networks in patients with drug-resistant partial epilepsy. It utilizes simultaneous recordings from surface techniques like magnetoencephalography (MEG) and electroencephalography (EEG), alongside depth recordings from intracerebral stereotactic EEG (SEEG). The study aims to identify the most relevant mechanisms of interaction between brain regions and to determine if information from depth recordings can be inferred from surface data alone. This research builds on previous work demonstrating the feasibility of these combined recording techniques.

Who should consider this trial

Good fit: Ideal candidates include adults undergoing pre-surgical evaluation for drug-resistant partial epilepsy who are eligible for SEEG implantation.

Not a fit: Patients who are minors, pregnant, or under legal guardianship will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved preoperative assessments and treatment strategies for epilepsy patients.

How similar studies have performed: While this approach is innovative, previous studies have shown promise in using combined recording techniques for brain network analysis.
