Central chemoreceptors: locations and functions

E Nattie, A Li - Comprehensive physiology, 2012 - pmc.ncbi.nlm.nih.gov
Central chemoreception traditionally refers to a change in ventilation attributable to changes
in CO2/H+ detected within the brain. Interest in central chemoreception has grown …

Central respiratory chemoreception

PG Guyenet, RL Stornetta… - Journal of Comparative …, 2010 - Wiley Online Library
By definition central respiratory chemoreceptors (CRCs) are cells that are sensitive to
changes in brain PCO2 or pH and contribute to the stimulation of breathing elicited by …

Peripheral chemoreceptor inputs to retrotrapezoid nucleus (RTN) CO2‐sensitive neurons in rats

ACT Takakura, TS Moreira, E Colombari… - The Journal of …, 2006 - Wiley Online Library
The rat retrotrapezoid nucleus (RTN) contains pH‐sensitive neurons that are putative central
chemoreceptors. Here, we examined whether these neurons respond to peripheral …

Defects in breathing and thermoregulation in mice with near-complete absence of central serotonin neurons

MR Hodges, GJ Tattersall, MB Harris… - Journal of …, 2008 - jneurosci.org
Serotonergic neurons project widely throughout the CNS and modulate many different brain
functions. Particularly important, but controversial, are the contributions of serotonin (5-HT) …

Central chemoreception is a complex system function that involves multiple brain stem sites

E Nattie, A Li - Journal of applied physiology, 2009 - journals.physiology.org
CENTRAL CHEMORECEPTION refers to detection of CO2/pH within the brain and the
subsequent reflex effects on breathing. It involves multiple sites within the hindbrain (9, 12 …

Control of breathing by raphe obscurus serotonergic neurons in mice

SD DePuy, R Kanbar, MB Coates… - Journal of …, 2011 - jneurosci.org
We used optogenetics to determine the global respiratory effects produced by selectively
stimulating raphe obscurus (RO) serotonergic neurons in anesthetized mice and to test …

Retrotrapezoid nucleus and central chemoreception

PG Guyenet, RL Stornetta… - The Journal of …, 2008 - Wiley Online Library
The 'distributed chemoreception theory'attributes the central chemoreflex (the stimulation of
breathing by CNS acidification) to the cumulative effects of pH on multiple classes of …

The good, the bad, and the deadly: adenosinergic mechanisms underlying sudden unexpected death in epilepsy

B Purnell, M Murugan, R Jani, D Boison - Frontiers in neuroscience, 2021 - frontiersin.org
Adenosine is an inhibitory modulator of neuronal excitability. Neuronal activity results in
increased adenosine release, thereby constraining excessive excitation. The exceptionally …

Medullary serotonin neurons and central CO2 chemoreception

AE Corcoran, MR Hodges, Y Wu, W Wang… - Respiratory physiology …, 2009 - Elsevier
Serotonergic (5-HT) neurons are putative central respiratory chemoreceptors, aiding in the
brain's ability to detect arterial changes in [Formula: see text] and implement appropriate …

Regulation of ventral surface chemoreceptors by the central respiratory pattern generator

PG Guyenet, DK Mulkey, RL Stornetta… - Journal of …, 2005 - jneurosci.org
The rat retrotrapezoid nucleus (RTN) contains neurons described as central chemoreceptors
