ACh and ATP mediate excitatory transmission in cat carotid identified chemoreceptor units in vitro (Elsevier, 2003)Several molecules have been proposed as excitatory transmitters between glomus (type 1) cells and nerve terminals of petrosal ganglion (PG) neurons in the carotid body (CB). We tested whether ACh and ATP have a role to ...
-
(Springer New York LLC, 2018)© 2018, Springer International Publishing AG, part of Springer Nature. The carotid body (CB) chemoreceptors sense changes in arterial blood gases. Upon stimulation CB chemoreceptors cells release one or more transmitters ...

Caracterización neuroquímica y sináptica del circuito istmo-tectal en la vía tectofugal de aves (Universidad de Chile, 2014)

(1997)We studied the effects of sodium nitroprusside, a nitric oxide donor, on the chemosensory responses to cyanide and nicotine in the cat carotid body. In situ, sodium nitroprusside infusion reduced the cyanide-evoked responses ...
-
(Elsevier, 2003)The petrosal ganglion (PG) is entirely constituted by the perikarya of primary sensory neurons, part of which innervates the carotid body via the carotid sinus nerve (CSN). Application of acetylcholine (ACh) or nicotine ...
-
(Elsevier, 2003)The petrosal ganglion (PG) provides sensory innervation to the carotid sinus and carotid body through the carotid (sinus) nerve (CN). Application of either acetylcholine (ACh) or adenosine 5′-triphosphate (ATP) to the PG ...
-
(1999)We have recently reported that application of acetylcholine (ACh) or nicotine to the petrosal ganglion - the sensory ganglion of the glossopharyngeal nerve - elicits a burst of discharges in the carotid nerve branch, ...
-
(2007)Exposure to chronic intermittent hypoxia (CIH) for 4 days enhances the cat carotid body (CB) chemosensory responses to acute hypoxia. However, it is not known if CIH enhances the responses of the petrosal ganglion (PG) ...

(2016)La proteína quinasa dependiente de Ca2+/Calmodulina II (CaMKII) es una molécula de señalización sináptica que se expresa abundantemente en el cerebro y que juega un rol crítico en la formación de memorias y la inducción ...
-
(1989)There are two kinds of fast activity in the ERG: fast retinal potentials (FRP), an irregular series of spiky wavelets and oscillatory potentials (OP), a rhythmic sequence of events. Corneal ERG from nine intact young carps, ...
-
(Elsevier, 2012)Nitric oxide (NO), at physiological concentrations, is a tonic inhibitory modulator of carotid body (CB) chemosensory discharges. NO modulates the chemoreception process by several mechanisms, indirectly by modifying the ...
-
(Frontiers Research Foundation, 2014)The petrosal ganglion (PG) is a peripheral sensory ganglion, composed of pseudomonopolar sensory neurons that innervate the posterior third of the tongue and the carotid sinus and body. According to their electrical ...
-
(Elsevier, 1999)NaCN is a classical stimulus used to elicit discharges from carotid body chemoreceptors. The effect is assumed to be mediated by glomus (type I) cells, which release an excitatory transmitter for the excitation of carotid ...
-
(1998)The petrosal ganglion innervates carotid body chemoreceptors through the carotid (sinus) nerve. These primary sensory neurons are activated by transmitters released from receptor (glomus) cells, acetylcholine (ACh) having ...
-
(1998)We studied the effects of the nitric oxide (NO) synthase inhibitor, Nω- nitro-L-arginine methyl ester (L-NAME), and the NO donor, sodium nitroprusside (SNP) on cat chemosensory responses to intravenous injections of NaCN ...
-
(1996)The petrosal ganglion contains most of the perikarya of sensory neurons of the glossopharyngeal nerve. We studied the number and size of neuronal somata in 4 petrosal ganglia from adult cats. Ganglia were serially sectioned ...
-
(Springer New York LLC, 2018)© 2018, Springer International Publishing AG, part of Springer Nature. The carotid body (CB) is the main arterial chemoreceptor involved in oxygen sensing. Upon hypoxic stimulation, CB chemoreceptor cells release ...
