Figure 9 - Electromyographic recording from interarytenoid and lateral cricoarytenoid muscles.

An example of electromyographic recording from interarytenoid and lateral cricoarytenoid muscles during a 2.5-cm middle esophageal balloon distention before (a) and after (b) bilateral cervical vagotomy. As seen, EMG activities induced by balloon distention are completely abolished after bilateral cervical vagotomy. (Source: Shaker et al.⁶¹ with permission from the American Physiological Association)
