Claim:
1. A lead for deep brain stimulation, comprising: a lead body having a proximal section adapted to be electronically coupled to a power source and a distal section having at least two electrode groups, the at least two electrode groups comprising: a first electrode group comprising at least one first electrode which is adapted for being positioned in a nucleus accumben of a brain; and a second electrode group comprising at least one second electrode which is adapted for being positioned in an anterior limb of an internal capsule of the brain; wherein the first electrode group and the second electrode group are configured to work together to stimulate said nucleus accumben and anterior limb of an internal capsule in the brain, wherein the proximal section of the lead body comprises at least two contact groups, the at least two contact groups comprising: stimulation parameters of the first electrode group and stimulation parameters of the second electrode group are independently adjustable and applied by the first contact group and the second contact group to the first electrode group and the second electrode group, respectively, so that different stimulation parameters can be outputted to said nucleus accumben and said anterior limb; and the first electrode group comprises two first electrodes which are separated by a first distance (P
