The goal of this trial is to study brain activity in epilepsy at high spatiotemporal resolution. Apart from the epileptogenic network (dysfunctional areas), the investigators will study human brain function.~The use of micro-electrode arrays allows to study the human brain a high spatiotemporal resolution, even at the single neuron level.~Scientific objectives of the current project:~To record neural signals from macro-electrodes and delineate the epileptogenic network and study brain function during specific tasks.~To record neural signals from micro-electrodes and delineate the epileptogenic network and study brain function during specific tasks.~Identifying pivotal regions for BMI applications and developing online decoding algorithms.~Comparing neural recordings to fMRI activity
Prospective interventional study with implantation of micro-electrodes to study the brain networks in epilepsy at high spatiotemporal resolution.
