AC, Anterior commissure; PC, posterior commissure; L, left; R, right. For contact numbering, left lead contacts are 0–3 (0 being nearest the tip), and right lead contacts are 8–11 (8 being nearest the tip); C is casing of the implanted pulse generator, used as the anode in monopolar stimulation configurations.
