CO2 chemoreflex contributions to ventilatory long‐term facilitation

The Journal of Physiology, EarlyView.
Abstract figure legend To determine whether changes in CO2 chemoreflex sensitivity contribute to ventilatory long‐term facilitation (LTF), we tested the hypothesis that hypercapnic acute intermittent hypoxia (AIH) induces ventilatory LTF and enhances peripheral, but not central, chemoreceptor CO2 chemoreflex sensitivity.

Hypoglossal nerve stimulation for treatment of obstructive sleep apnea (OSA): a primer for oral and maxillofacial surgeons

Maxillofacial Plastic and Reconstructive Surgery, 2017
The prevalence of obstructive sleep apnea (OSA) is estimated to be 1–5% of the adult population world-wide, and in Korea, it is reported at 4.5% of men and 3.2% of women (Age 40 to 69 years old).

Electrical stimulation of the hypoglossal nerve: a potential therapy

Journal of Applied Physiology, 2014
Obstructive sleep apnea is characterized by recurrent episodes of pharyngeal collapse, which result from a decrease in pharyngeal dilator muscle tone. The genioglossus is a major pharyngeal dilator that maintains airway patency during sleep. Early studies in animal and humans have demonstrated that electrical stimulation of this muscle reduces ...

Electrophysiological properties of the dorsal motor nucleus of the vagus motoneurones controlling airway mucus secretion in rats

The Journal of Physiology, EarlyView.
Abstract figure legend Acidosis depolarises parasympathetic respiratory motoneurones in the dorsal motor nucleus of the vagus (DMV) and increases their firing frequency by reducing TWIK‐2 channel conductance. Acidosis also activates astrocytes, which further enhance neuronal excitability through NMDA receptor‐dependent glutamatergic signalling.

[Hypoglossal nerve stimulation in patients with CPAP failure : Evolution of an alternative treatment for patients with obstructive sleep apnea].

, 2017
Obstructive sleep apnea (OSA) is a common disease in western industrialized countries with increasing prevalence. Gold standard of therapy is nocturnal positive pressure ventilation by continuous positive airway pressure (CPAP).

Corticobulbar motor evoked potentials from tongue muscles used as a control in cervical spinal surgery

Clinical Neurophysiology Practice, 2017
Objective: Motor evoked potentials (MEPs) changes might be caused to the non-surgically induced factors during cervical spinal surgery. Therefore, control MEPs recorded cranially to the exit of the C5 root are highly recommendable in cervical spinal ...

Temperature‐Controlled Radiofrequency for Severe Nasal Airway Obstruction: A Non‐Inferiority Comparison With Surgical Intervention

International Forum of Allergy &Rhinology, Volume 16, Issue 10, Page 1073-1083, October 2026.
ABSTRACT Introduction Temperature‐controlled radiofrequency (TCRF), septoplasty (ST) with turbinate reduction, and functional rhinoplasty (FR) are treatment options for nasal airway obstruction (NAO) and nasal valve dysfunction (NVD), but no direct comparison of these procedures has been performed. Methods This prospective, open‐label, non‐inferiority (

Finite Element Analysis of Upper Airway in Ansa Cervicalis Stimulation for Obstructive Sleep Apnea

The Laryngoscope, Volume 136, Issue 10, Page 4575-4584, October 2026.
We developed a subject‐specific FE model to investigate how ACS stabilizes the upper airway in OSA. Simulations demonstrate that caudal traction applied through the hyolaryngeal complex produces coordinated multilevel airway stabilization, with pronounced effects at the retropalatal and retro‐epiglottic regions under physiologic loading.

Postsynaptic Potentials in the Hypoglossal Motoneurons Set up by Hypoglossal Nerve Stimulation

The Japanese Journal of Physiology, 1979
In nembutalized cats intracellular potentials were recorded from hypoglossal motoneurons innervating either protruder or retractor muscles of the tonge (protruder and retractor motoneurons: P-Mns and R-Mns). Responses to stimulation of the hypoglossal nerve were explored and found to consist of an antidromic spike followed by an afterhyperpolarization (

Wireless Power Transfer-Enabled Optogenetic Stimulation of Hypoglossal Motoneurons in Mice for Functional Studies in Obstructive Sleep Apnea

IEEE Journal of Microwaves
Obstructive sleep apnea (OSA) is a widespread sleep-related breathing disorder linked to cardiovascular and cognitive complications. Although continuous positive airway pressure (CPAP) remains the standard therapy, poor patient adherence limits its ...
