The SEEG implantation is performed on purely clinical criteria for preoperative diagnosis. Magnetoencephalography and EEG are purely passive techniques that do not involve any additional risk. This project is a continuation of an existing project in which it was demonstrated the feasibility of simultaneous SEEG and MEG/EEG recordings.

20 patients per presumed location of the epileptogenic zone (see experimental plan) for a total of 120 patients, including 30 minors. For patients, a MEG-EEG-SEEG examination during the SEEG exploration period.
For the control population, 120 control subjects, including 30 minors, that is to say as many as patients. For control subjects, a MEG-EEG exam.
It will be simultaneously record the surface EEG, the MEG and in patients only the intracerebral EEG (SEEG). In the case of SEEG with micro contacts, these additional signals will also be recorded in parallel and will provide greater sensitivity to high frequency activities. The physiological networks will be studied in patients thanks to stimulations (external or intracerebral) carried out within the framework of the functional cartography, and the pathological networks thanks to measures in state of rest. For external stimulation protocols, it will be constitute a reference base in MEG and EEG alone (non-invasive) on control subjects.
Registry-reported names are shown in full. Names without a link have not yet been matched to a Syfrah profile.
The patients will be recruited in the Service of Epileptology and Cerebral Rhythmology of the Timone. Only major and minor control subjects will be recruited following the announcement of the experience by posting on different sites or other appropriate means of communication.
