Abstract
Methods and systems can facilitate visualizing cathodic and anodic stimulation separately. Alternately, the methods and systems may separately visualize stimulation of different neural elements, such as nerve fibers and neural cells. These methods and systems can further facilitate programming an electrical stimulation system for stimulating patient tissue.
