Stereotactic electroencephalography

Abstract

Stereotactic implantation of depth electrodes for surgical evaluation of drug-resistant epilepsy is the technique of choice in many centers across the world. Historically, the choice of depth versus subdural electrodes has been largely dependent on the training of epileptologists and epilepsy surgeons in light of their comfort level with implantation procedures and interpretation of clinical data. In this review, we provide a historical perspective and clinical update regarding recommendations for the use of stereoelectroencephalography (SEEG) with respect to recent outcomes data, technological advances in multimodal imaging, and signal analysis.
