![]() ![]() ![]() You will not see the bolts or the electrodes as your head will be wrapped with a bandage through the entire hospital stay. Each electrode is held in place by a bolt that attaches to the bone. To insert each electrode, we will make a small incision in the skin and a small hole in the bone, just big enough to pass the electrode. We will put the electrodes into the brain areas where we suspect seizures might be starting. These electrodes are thin, floppy wires about the thickness of a spaghetti noodle. We are going to place several (~10-15) electrodes into your brain. ![]() An analogy is that through your non-invasive testing, we have found the zip code of your seizures, but before we can proceed with surgery, we must also find the street and house number of where your seizures live. We need to do a diagnostic surgery, called SEEG, to determine the precise location. The testing you have had so far has helped us gather important information about where in your brain your seizures are coming from, but we have not been able to pinpoint the exact spot. He is also a pioneer of robotic-assisted neurosurgery, which improves accuracy and shortens surgery time. Gonzalez was the first epilepsy surgeon in the US to offer SEEG and has performed over 1000 cases. At UPMC, we use robotic assistance with ROSA® to accurately and efficiently place the electrodes for seizure mapping. SEEG is the surgical implantation of electrodes into the brain in order to better localize the seizure focus.
