Sometimes robots such as the ROSA™ are used to place the electrodes. The is why children are sedated during this procedure. It can also be challenging to work around the frame and adjust the angle and location of the electrodes when SEEG is performed during surgery. The frame allows doctors to probe within 3 millimeters of the target site in the brain however, the frame takes time to position and can cause discomfort. Then, long, thin electrodes are inserted through the skin and the skull into the brain.

During the first stage, brain imaging is done with MRI and locations are marked. Typically, the procedure begins when a metal frame is placed over the patient’s head to help label, align and implant the electrodes. This process can capture a three-dimensional understanding of seizure activity in the brain. The position of the electrodes is reconstructed using computed tomography (CT) superimposed on magnetic resonance imaging (MRI), or via direct MRI if the electrodes are compatible. In SEEG, electrodes are inserted into the brain to help define the epileptogenic zone (where seizures begin) and can often identify a target for surgery. In these cases, stereotactic electroencephalography (SEEG) may be useful. In some cases of drug-resistant focal epilepsy, a routine EEG may not be enough to determine where a seizure begins or to identify parts of the brain that control motor function and speech.
