Functional mapping involves neurosurgeons placing electrodes in the form of wires or flexible sheets (called strips and grids) on or in brain tissue to map the precise origin of seizures. Grid electrodes can be used both for recording and stimulating brain tissue to identify the underlying function of that region, such as language, sensation or motor function.
Mapping identifies brain regions that are involved in specific functions like recognizing faces. The map of where seizures arise helps surgeons avoid these critical areas while operating. Invasive electrodes remain in place for a few days up to 1-2 weeks to record and map seizures. They are then removed and epilepsy surgery is performed, if findings indicate you are a good candidate for surgery.
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
