STEREOTACTIC NEUROSURGERY
Stereotactic Neurosurgery is used to facilitate the management of abnormal movements, therefore dealing with the symptoms and not the disease itself. Depending on the side and part of the body that is aimed to improve, the neurosurgeon knows which spot in the brain has to be altered to achieve it; that is the TARGET. This is a three dimensional technique for Neurosurgery. It consists in taking some X-rays (or other imaging aid) , based in which a structure within the brain (nucleus) is located and mapped. Once this is done, the coordinates are moved to a stereotactic frame which will guide an electrode to the exact location.
Stereotactic Neurosurgery
Most of the time, the procedure is done under local anesthesia, depending on the conditions of the patient. The stereotactic frame is fixed in the skull and the electrode is driven through a burrhole. While small electrical discharges are applied intermittently, the surgeon watches the response of the patient and in this way he knows the exact position of the electrode within the brain. Once in the target, a larger electrical impulse is sent through the electrode to modify the brain cells at that spot. Typically the patients are sent immediately to their room and the next day are discharged from the hospital.
