VNS is a form of stimulation whereby electricity is applied to the vagus nerve to modulate the central nervous system. The Vagus nerve is the 10 th cranial nerve, which runs from the brainstem, through the neck, down to the abdomen. Like DBS, VNS is done by surgically implanting a neurostimulator in the chest, while running a wire around the left vagus nerve. (Efferent heart fibers exist on the right.)
