In contrast, the smart vagus, which originates in the nucleus ambiguus, is distinctly mammalian, and mediates cardiac activity when environmental demands require extrareptilian coping. The autonomic component is mediated by the myelinated vagus, which reduces fear and promotes calm behavioral states. The vagus also regulates the stress response in other organs such as the bronchi, esophagus, pharynx, and heart. This neural influence on the heart is proposed to originate from the nucleus ambiguus via myelinated tracts of the vagus (10th cranial nerve). The contribution of the vagus nerve in interleukin-1 beta-induced fever is dependent on dose. The vagus, the primary parasympathetic pathway to the heart, rapidly regulates cardiac output during environmental challenge. The deceleratory parasympathetic component is provided by the vagus, or tenth cranial nerve. These actions are opposed by parasympathetic innervation via the vagus nerve. The vagus has an inhibitory effect on the contraction of the laryngeal muscles. The physiological connection between distress and high-pitched crying is mediated by the vagus, in particular the branch of the vagus linking the nucleus ambiguus to the larynx. Acoustic analyses of the infant cry emphasize measures of the fundamental frequency, in part because cry production models emphasize the role of the vagus and its relationship to fundamental frequency. This method utilizes an electrode implanted near the medulla in order to send electrical impulses to the vagus nerve.
