BRAIN ELECTROSTIMULATION
Photo essay from hospital. The operation is generally executed under local anesthesia, except in cases like this one, where the patient is under general anestesia. Adjusting the stereotactic frame. Next, targeting panels will be placed, for the X-rays that will used for the duration of the surgery. Using a gamma-camera and injecting contrast-liquid permits a more precise visualization of the cerebral regions and thalamic area. Hospital of Lille, in the Nord region of France. Bilateral thalamic stimulation is used to treat Parkinsons disease (PD), epilepsy, obsessive compulsive disorder (OCD), and migraines. Electrical stimulation of neural elements considerably improves the symptoms of patients afflicted with PD. Electrodes are stereotactically implanted in the thalamic ventralis intermedius (VIM) after the location is pinpointed using 3D-MRI and the monitoring of cellular activity. The electrode is linked to a cutaneous, programmable stimulator. The intervention can be bilateral. Currently, quadripolar electrodes are generally used.
