1. A method of providing electrical stimulation to the brain of a patient using an implantable pulse generator (IPG) implantable in the patient's tissue, wherein the IPG comprises a plurality of current sources and a metallic case and wherein the IPG is configured to connect to one or more electrode leads implantable in the patient's brain, wherein each of the one or more electrode leads comprise a plurality of electrodes, the method comprising:
determining a therapeutic waveform to provide to the patient's brain, wherein the waveform comprises an anodic leading phase having an amplitude absolute value greater than or equal to an amplitude absolute value of any other phase of the therapeutic waveform,
connecting a first one or more of the plurality of current sources to one or more of the plurality of electrodes to provide the therapeutic waveform to the patient's brain, and
connecting a second one or more of the plurality of current sources to the metallic case to provide a second waveform to the patient's tissue, wherein the second waveform has a polarity that is opposite to that of the therapeutic waveform.
