New brain scanner could sharpen epilepsy surgery targeting

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Patients aged 6 to 65 2. Patients suffering from partial epilepsy that has been developing for at least 2 years, drug-resistant, regardless of the presumed topographical origin or suggested cause (lesional with or without MRI abnormality) and for whom the following have been decided and planned: either i) a surgical procedure to resect the epileptogenic zone without prior intracranial EEG recording or ii) intracranial EEG recording necessary before a possible cortical resection procedure 3. Patients who have undergone routine prolonged scalp video EEG recording showing interictal paroxysmal abnormalities 4. Patients motivated to participate effectively in the project 5. Patients who have signed an informed consent form to participate in the study Exclusion Criteria: 1. Patients with neurological or psychiatric disorders or a history of neurological or psychiatric disorders, sleep disorders other than epilepsy that may impact the variability or quality of the data or the cooperation and retention of the participant, which will be assessed by the principal investigator or co-investigator during the inclusion interview. 2. Patients with contraindications common to MEG and MRI examinations: * Metal in the body that is incompatible with the examination (pacemaker, implanted pump including insulin pump, neurostimulator, cochlear implants or other hearing devices, metal prosthesis, intracerebral/surgical clips for aneurysms, implantable defibrillators, ferromagnetic foreign bodies in the eyes or brain in the upper body, ventriculoperitoneal neurosurgical shunt valves, dental braces or steel pivots for dental root canals, ferromagnetic foreign bodies in the upper body) * Claustrophobia 3. Pregnant women, breastfeeding women, or women who have given birth within the last 6 months. 4. Patients under guardianship, curatorship, or judicial protection 5. Patients deprived of their liberty 6. Patients not affiliated with a social security system or beneficiaries of such a system
