A method of using deep brain stimulation (DBS) for treating mental disorders associated with high connectivity in brain circuits, such as cortico-striato-thalamo-cortical (CSTC) circuits, is provided. The method comprises providing a first electrical signal having a first frequency to a first electrode implanted at a first location within a brain circuit and providing a second electrical signal having a second frequency to a second electrode implanted at a second location within the brain circuit. The first frequency and the second frequency are unequal.
