An implantable medical lead includes a lead body, a first electrode, a second electrode, a third electrode, and a fourth electrode. The electrodes are located at fixed positions along the length of the lead body, and the second and third electrodes are positioned between the first and fourth electrodes. The first electrode has a proximal end, the fourth electrode has a distal end, and the distance from the proximal end of the first electrode to the distal end of the fourth electrode is between 5 centimeters and 7 centimeters. The combined length of the second and third electrodes is between 2.5 and 5 times greater than the combined length of the first and fourth electrodes. The lead may be used for applying electrical signals to an occipital nerve of a patient.
