Peripheral Nerve Stimulation Model (IMAGE) Duke University Caption A new tool to model peripheral nerve stimulation rapidly discovered optimal electrical waveforms (white traces) which, when delivered through the metal contacts of a cuff electrode placed on the vagus nerve, activates only therapeutic target fibers (in green) to avoid side effects. The optimization process involves testing thousands of different candidate solutions, as depicted by the population of cuffed nerves.
