Laryngeal Afferent Activity and its Role in the Control of Breathing

The afferent activity emerging from the larynx travels through the superior laryngeal nerve and the recurrent laryngeal nerve. Recording whole nerve activity from the internal branch of the superior laryngeal nerve, the pathway which carries most of the laryngeal afferent information, reveals a clear respiratory-related activity. This respiratory modulation is related to changes in transmural pressure, activity of laryngeal muscles, pulling on the larynx due to the respiratory movements of the trachea and changes in temperature.
