1. A method of treating a disorder in a patient, comprising: positioning a device adjacent to a skin surface of the patient; generating one or more electrical impulses with said device; and transmitting the electrical impulses to a vagus nerve in the patient, the electrical impulses having an electric field at the vagus nerve above a threshold for generating action potentials within fibers of the vagus nerve responsible for activating neural pathways causing release of inhibitory neurotransmitters within a brain of the patient.
