A: Surgeons drill a small hole in the skull and carefully place specially-made wires (leads) into specific parts of the brain using a special guidance frame or robot. The leads are connected to an electrical pulse generator (similar to a pacemaker) placed under the skin over the chest.

The procedure, which can last as little as three hours, is often done with the patient awake.
