The dorsal medulla encompassing the nucleus of the tractus solitarius (NTS) and
surrounding reticular formation (RF) has an important role in processing sensory information
from the upper and lower airways for the generation and control of airway protective
behaviors. These behaviors, such as cough and swallow, historically have been studied in
isolation. However, recent information indicates that these and other airway protective
behaviors are coordinated to minimize risk of aspiration. The dorsal medullary neural circuits …
