Motor control of the upper airway muscle genioglossus. This project aims to evaluate a recent proposal about the motor control of the upper airway muscle Genioglossus. The upper airway muscles, the most complex in the human body, are critical for breathing and speaking, but are not well understood. Genioglossus draws the base of the tongue forward to maintain airway patency. This project will study genioglossus during wakefulness and sleep in normal healthy individuals. It is anticipated that th ....Motor control of the upper airway muscle genioglossus. This project aims to evaluate a recent proposal about the motor control of the upper airway muscle Genioglossus.

Genioglossus draws the base of the tongue forward to maintain airway patency. This project will study genioglossus during wakefulness and sleep in normal healthy individuals. It is anticipated that the project will suggest improved avenues for treatment of sleep related respiratory disorders.Read moreRead less
Understanding the physiological changes accompanying arousal from sleep. This project aims to investigate neural memory in upper airway dilator muscles. Following brief awakening from sleep (arousal), upper airway dilator muscle activity is elevated for 20–30 seconds despite inhibitory stimuli being present. The cause for the elevated activity is unknown. This project aims to investigate whether a form of neural memory contributes to the elevated activity. It expects to demonstrate that arousal ....Understanding the physiological changes accompanying arousal from sleep. This project aims to investigate neural memory in upper airway dilator muscles. Following brief awakening from sleep (arousal), upper airway dilator muscle activity is elevated for 20–30 seconds despite inhibitory stimuli being present. The cause for the elevated activity is unknown. This project aims to investigate whether a form of neural memory contributes to the elevated activity. It expects to demonstrate that arousal can induce a neural memory that is not inhibited by usual stimuli. The findings are expected to increase our understanding of normal human functioning but may also have implications for conditions where upper airway muscles are important such as dysphagia, sleep apnea and numerous other sleep disorders.Read moreRead less
