This is a stereotactic operation. Through a sonde placed in the brain, electrodes are put on specific locations of the STN. These electrodes are connected by wires to a "pacemaker" placed below the clavicle bone. The "pacemaker" stimulates the STN with electric pulses, thus reducing / suppressing PD symptoms. The most effective one is bi-lateral, some researchers even indicate it might slow down the progression of PD. Hans.
