Several days after the operation and after the placement of the ´batterie´ under the clavicle. The battery is barely visible because it is hidden by the probe that the doctor is using to verify the electrode and to make adjustments. These adjustments will continue regularly and will change, as the disease continues to evolve. Hospital of Lille, in the Nord region of France. Bilateral thalamic stimulation is used to treat Parkinson’s 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.
