The Kolliker-Fuse nucleus orchestrates the timing of expiratory abdominal nerve bursting
(Amer Physiological Soc, 2018-02-01)
Coordination of respiratory pump and valve muscle activity is essential for normal breathing. A hallmark respiratory response to hypercapnia and hypoxia is the emergence of active exhalation, characterized by abdominal ...
Modificações ventilatórias induzidas pela hipóxia intermitente aguda em condições não anestesiadas
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Ciências Fisiológicas - PIPGCFCâmpus São Carlos, 2020-03-27)
It has been described that intermittent hypoxia (IH, periods of hypoxia followed by normoxia), as observed in some pathological situations, promotes, acutely, a sustained increase in respiratory motor activity, dependent ...
Geração de expiração ativa : mecanismos centrais e implicações nas alterações cardiorrespiratórias associadas à hipóxia intermitente
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Ciências Fisiológicas - PIPGCFCâmpus São Carlos, 2016-08-05)
The exposure to periods of hypoxemia and reoxygenation, as observed in patients with
obstructive sleep apnea (OSA), promotes compensatory increases in ventilation, sympathetic activity and blood pressure (BP), by mechanisms ...
Short-Term Sustained Hypoxia Elevates Basal and Hypoxia-Induced Ventilation but Not the Carotid Body Chemoreceptor Activity in Rats
(Frontiers Media Sa, 2018-02-27)
Exposure to chronic sustained hypoxia (SH), as experienced in high altitudes, elicits an increase in ventilation, named ventilatory acclimatization to hypoxia (VAH). We previously showed that rats exposed to short-term(24 ...
Interaction between the retrotrapezoid nucleus and the parafacial respiratory group to regulate active expiration and sympathetic activity in rats
(Amer Physiological Soc, 2018-11-01)
The retrotrapezoid nucleus (RTN) contains chemosensitive cells that distribute CO2-dependent excitatory drive to the respiratory network. This drive facilitates the function of the respiratory central pattern generator ...
Intermittent hypoxia-induced sensitization of central chemoreceptors contributes to sympathetic nerve activity during late expiration in rats
