Interaction between the retrotrapezoid nucleus and the parafacial respiratory group to regulate active expiration and sympathetic activity in rats
(Amer Physiological Soc, 2018-11-01)
The retrotrapezoid nucleus (RTN) contains chemosensitive cells that distribute CO2-dependent excitatory drive to the respiratory network. This drive facilitates the function of the respiratory central pattern generator ...
Increased sympathetic activity in normotensive offspring of malignant hypertensive parents compared to offspring of normotensive parents
(Associação Brasileira de Divulgação Científica, 2008)
Malignant hypertension seems to be the consequence of very high blood pressure. Furthermore, an increase in sympathetic and renin-angiotensin system activity is considered to be the main mechanisms producing malignant ...
Role of the Carotid Body Chemoreflex in the Pathophysiology of Heart Failure: A Perspective from Animal Studies
(Springer New York LLC, 2015)
Role of the caudal pressor area in the regulation of sympathetic vasomotor tone
(Associação Brasileira de Divulgação Científica, 2008-07-01)
It is well known that the ventrolateral medulla contains neurons involved in the tonic and reflex control of the cardiovascular system. Two regions within the ventrolateral medulla were initially identified: the rostral ...
THE INVOLVEMENT OF THE SYMPATHETIC NERVOUS-SYSTEM IN MEAL-INDUCED THERMOGENESIS IN MICE
(Stockton Press, 1991-11-01)
The acute effect of food intake on the activity of the sympathetic nervous system (SNS) in both heart and brown adipose tissue (BAT) was investigated in mice. Upon delivery to the laboratory mice were housed singly and ...
Sympathetic nerve activity is decreased during device-guided slow breathing
(NATURE PUBLISHING GROUP, 2010)
It is known that slow breathing (<10 breaths min(-1)) reduces blood pressure ( BP), but the mechanisms involved in this phenomenon are not completely clear. The aim of this study was to evaluate the acute responses of the ...
