Multiple Central Chemoreceptor Sites: Cell Types and function in vivo
2008Central chemoreception is a distributed property involving many sites and neuronal types. Focal acidosis in conscious or anesthetized animals at many hindbrain sites stimulates breathing. The steady-state CO2 response in conscious animals is reduced by cell specific lesions of catecholamine, 5HT or neurokinin-1 receptor (NK1R) expressing neurons and by

Temporal Resolution in Olfaction: Stimulus Integration Time of Lobster Chemoreceptor Cells
Journal of Experimental Biology, 1996ABSTRACT The stimulus integration time of lobster olfactory receptor cells in situ was determined using extracellularly recorded spiking responses from receptor cells and on-line high-resolution measurement of odor square pulses. At a fixed odor concentration, odor steps of 200 ms duration elicited maximum responses; shorter odor steps ...

Acute oxygen sensing—Role of metabolic specifications in peripheral chemoreceptor cells
Respiratory Physiology & Neurobiology, 2019Acute oxygen sensing is essential for humans under hypoxic environments or pathologic conditions. This is achieved by the carotid body (CB), the key arterial chemoreceptor, along with other peripheral chemoreceptor organs, such as the adrenal medulla (AM).

GABAergic Pump Cells of Solitary Tract Nucleus Innervate Retrotrapezoid Nucleus Chemoreceptors
Journal of Neurophysiology, 2007The retrotrapezoid nucleus (RTN) contains central respiratory chemoreceptors that are inhibited by activation of slowly adapting pulmonary stretch receptors (SARs). Here we examine whether RTN inhibition by lung inflation could be mediated by a direct projection from SAR second-order neurons (pump cells).

Polar Location of the Chemoreceptor Complex in the Escherichia coli Cell
Science, 1993The eukaryotic cell exhibits compartmentalization of functions to various membrane-bound organelles and to specific domains within each membrane. The spatial distribution of the membrane chemoreceptors and associated cytoplasmic chemotaxis proteins in Escherichia coli were examined as a prototypic functional ...

Peripheral Filters and Chemoreceptor Cells in Fishes
1988Olfaction in vertebrates is the sense used in the processing of chemical information that is detected and transmitted to the central nervous system by bipolar neurons that compose the olfactory nerve (cranial nerve I). Gustation is the sense used in the processing of chemical information that is detected by taste cells and transmitted centrally by ...

Developmental changes in intracellular Ca2+ response of carotid chemoreceptor cells to hypoxia
American Journal of Physiology-Lung Cellular and Molecular Physiology, 1995The carotid chemoreceptor response to hypoxia is weak just after birth and increases during postnatal development. The mechanisms underlying chemoreceptor maturation are unknown. We tested the hypothesis that carotid chemoreceptor maturation occurs at the glomus cell level by measuring intracellular calcium ([Ca2+]i) mobilization in response to ...

Hypoxic Ventilatory Depression May be Due to Central Chemoreceptor Cell Hyperpolarization
1995By re-examining the results of various studies of HVD, of the localization of medullary CO2 chemosensory cells, and of their acid secretion, an hypothesis has been developed suggesting that the neurones which detect increased CO2 or CSF acid respond to decreased transmembrane H+ gradient, i.e. a greater fall in ECF than in ICF pH.
