Role of preoptic opioid receptors in the body temperature reduction during hypoxia
(Brain Research, 2009-08-25) [Artigo]
Evidence indicates that endogenous opioids play a role in body temperature (Tb) regulation in mammals but no data exist about the involvement of the specific opioid receptors, mu, kappa and delta, in the reduction of Tb ...
Role of central nitric oxide in behavioral thermoregulation of toads during hypoxia
(Physiology & Behavior, 2008-09-03) [Artigo]
Nitric oxide (NO) is thought to play a key role in the development of hypoxia-induced anapyrexia in mammals, acting on the preoptic region of the anterior hypothalamus to activate autonomic heat loss responses. Regarding ...
Locus coeruleus noradrenergic neurons and CO2 drive to breathing
(Pflugers Archiv: European Journal of Physiology, 2008-03-01) [Artigo]
The Locus coeruleus (LC) has been suggested as a CO2 chemoreceptor site in mammals. In the present study, we assessed the role of LC noradrenergic neurons in the cardiorespiratory and thermal responses to hypercapnia. To ...
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. ...
Respiratory chemoreceptor function in vertebrates - Comparative and evolutionary aspects
(Integrative and Comparative Biology, 2007-10-01) [Artigo]
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 ...
