Caption: Electrode implants for Parkinson's disease. X-ray of the head of a Parkinson's disease patient in side view, during surgery to implant electrodes in the brain. Pegs (left, right) are from a metal frame fitted to the patient's head which allows electrodes to be aimed accurately. Two quadripolar electrodes are visible deep in the brain, fixed permanently by screws on the cranium. Parkinson's disease is due to a degeneration of nerve cells in the basal ganglia of the brain. It causes muscle tremor and a rigid posture in the elderly. By implanting electrodes to stimulate diseased areas of the brain, trembling in the patient is stopped. If the electrodes are removed, trembling resumes.
