A tongue‐twister to translation? Increased complexity of genioglossus movement during wakefulness in persons with obstructive sleep apnoea

The human pharyngeal airway is a compliant muscular conduit prone to collapse, particularly during sleep when efferent motor outflow from the brainstem to multiple muscles of the upper airway wanes owing to state-dependent alterations in brainstem neuromodulatory systems. Movement of the muscular compartments of the genioglossus, the principal airway dilator muscle, is essential in the maintenance of airway calibre during inspiration when a...
