Serotonergic mechanisms on breathing modulation in the rat locus coeruleus
(Pflugers Archiv: European Journal of Physiology, 2010-02-01) [Artigo]
The locus coeruleus (LC) is a noradrenergic nucleus that plays an important role in the ventilatory response to hypercapnia. This nucleus is densely innervated by serotonergic fibers and contains high density of serotonin ...
Cardiorespiratory effects of gap junction blockade in the locus coeruleus in unanesthetized adult rats
(Respiratory Physiology & Neurobiology, 2014-01-01) [Artigo]
The locus coeruleus (LC) plays an important role in central chemoreception. In young rats (P9 or younger), 85% of LC neurons increase firing rate in response to hypercapnia vs. only about 45% of neurons from rats P10 or ...
Periaqueductal gray matter modulates the hypercapnic ventilatory response
(Pflugers Archiv: European Journal of Physiology, 2012-08-01) [Artigo]
The periaqueductal gray (PAG) is a midbrain structure directly involved in the modulation of defensive behaviors. It has direct projections to several central nuclei that are involved in cardiorespiratory control. Although ...
Brain monoaminergic neurons and ventilatory control in vertebrates
(Respiratory Physiology & Neurobiology, 2008-12-10) [Artigo]
Monoamines (noradrenaline (NA), adrenaline (AD), dopamine (DA) and serotonin (5-HT) are key neurotransmitters that are implicated in multiple physiological and pathological brain mechanisms, including control of respiration. ...
Ionotropic glutamatergic receptors in the rostral medullary raphe modulate hypoxia and hypercapnia-induced hyperpnea
(Respiratory Physiology & Neurobiology, 2011-01-31) [Artigo]
It has been suggested that the medullary raphe (MR) plays a key role in the physiological responses to hypoxia and hypercapnia. We assessed the role of ionotropic glutamate receptors in the rostral MR (rMR) in the respiratory ...
