Electric stimulation using stereoelectroencephalography electrodes

Abstract

Electrical stimulation (ES) using stereoelectroencephalography is an essential component in the workup of surgical epilepsy. ES helps to solve two major problems in epilepsy surgery – total resection of the epileptogenic lesion while minimising the postoperative neurological deficit. ES allows to induce habitual epileptic seizures to define the neurophysiological characteristics and boundaries of the epileptogenic zone and to map eloquent areas to reduce the area of resection with prediction of post-operative neurological deficit. The results of studies using ES make a huge contribution not only to practical medicine, but also to fundamental science, allowing us to study the functions of individual parts of the brain and to understand the elements of the pathogenesis of various diseases of the nervous system.
