Central circuits that process superior laryngeal nerve sensory feedback: It’s complicated.

About the Seminar
Perturbations of peripheral sensory systems with devices have the potential to profoundly modify the behavior of central control circuits. These actions can lead to therapeutic effects or deleterious side effects mediated by the CNS that hinder device development. The functional organization of these circuits, especially those that mediate vagal reflexes, remains poorly understood. We have investigated the central pathways that mediate a simple reflex from the superior laryngeal nerve, the laryngeal adductor reflex. These efforts have revealed a control system that exerts tight regulation of reflex excitability and is not easily predictable based on knowledge of the afferent system alone.
