Hypercarbic cardiorespiratory reflexes in the facultative air-breathing fish jeju (Hoplerythrinus unitaeniatus): the role of branchial CO2 chemoreceptors
(Company of Biologists Ltd, 2010-08-15)
The aim of the present study was to determine the roles that externally versus internally oriented CO2/H+-sensitive chemoreceptors might play in promoting cardiorespiratory responses to environmental hypercarbia in the ...

Peripheral chemoreceptor inputs to retrotrapezoid nucleus (RTN) CO2-sensitive neurons in rats
(Blackwell Publishing, 2006-04-15)
The rat retrotrapezoid nucleus (RTN) contains pH-sensitive neurons that are putative central chemoreceptors. Here, we examined whether these neurons respond to peripheral chemoreceptor stimulation and whether the input is ...
Carotid body chemoreceptors: physiology, pathology, and implications for health and disease
(NLM (Medline), 2021)
The carotid body (CB) is the main peripheral chemoreceptor for arterial respiratory gases O2 and CO2 and pH, eliciting reflex ventilatory, cardiovascular, and humoral responses to maintain homeostasis. This review examines ...
Theoretical perspectives on central chemoreception - intrinsic excitation-inhibition mechanisms in brainstem chemoreceptors
(UniandesDoctorado en IngenieríaFacultad de Ingeniería, 2016)
The aim of this work was to investigate intrinsic mechanisms of activation and inhibition of the C02 response in central chemoreceptors. We employed computational single neuron modeling to simulate the basic electrochemical ...
Respiratory chemoreceptor function in vertebrates - Comparative and evolutionary aspects
(2007-10-01)
The sensing of blood gas tensions and/or pH is an evolutionarily conserved, homeostatic mechanism, observable in almost all species studied from invertebrates to man. In vertebrates, a shift from the peripheral O2-oriented ...

Localização e orientação dos quimiorreceptores de CO2 e/ou pH envolvidos no controle dos reflexos cardio-respiratórios e da respiração aérea em jeju, Hoplerythrinus unitaeniatus (Teleostei, Erythrinidae).
(Universidade Federal de São CarlosBRUFSCarPrograma Interinstitucional de Pós-Graduação em Ciências Fisiológicas - PIPGCF, 2004-01-03)
In the present study we determined the location and orientation of the CO2 and/or pH chemoreceptors and analyzed the cardio-respiratory responses and the aerial respiration in jeju (Hoplerythrinus unitaeniatus) during ...
