SEEG is part of phase 2 evaluation performed in patients with refractory epilepsy in which the noninvasive work up was not able to clearly identify the epileptogenic zone. SEEG is typically performed by a neurosurgeon at Clinique Universitaires Saint Luc (CUSL).
The procedure consists in introducing through the skull, multiple intracranial electrodes inside the brain parenchyma in order to record more accurately the electrophysiological activity of different regions of interest- selected after a multimodal epilepsy work-up. Due to its invasive nature, implying some limited surgical risks, these recordings are limited to highly selected epileptic patients.
The epilepsy and Neurostimulation Lab has direct acces to this patient population through collaboration with the Center of Refractory Epilepsy and the department of Neurosurgery of Cliniques Universitaires Saint-Luc
