System identification of dynamic closed-loop cardiovascular control of total peripheral resistance by arterial and cardiopulmonary baroreceptors
… the examination of arterial and cardiopulmonary baroreceptors in the dynamic closed-loop short-term control of Ra. 2) develop and apply a system identification method for the analysis of fluctuations in Pa, right atrial pressure (Pra), and Ra to quantitatively characterize the physiologic …

Functional contributions of a sex-specific population of myelinated aortic baroreceptors in rat and their changes following ovariectomy
Gender differences in the basal function of autonomic cardiovascular control are well documented. Consistent baroreflex (BRx) studies suggest that women have higher tonic parasympathetic cardiac activation compared to men. Later in life and concomitant with menopause, a significant reduction in the …

Renal failure and the neural control of the kidney
… controlled RSNA by the high and low pressure baroreceptors. Baroreflex gain curves for both RSNA and HR were generated in control and RF rats. This study clearly showed a blunted high-pressure baroreflex in RF rats, an impairment which was almost completely corrected by bilateral renal …

The Baroreflex And Neurogenic Control Of Cerebral Autoregulation In Cerebral Blood Flow
… (BR) have prompted suggestions that the baroreceptors might supply neurogenic input to the cerebral vasculature. Alternative potential inputs have also not been explored. A head up tilt (HUT) protocol offers an established way to investigate CA further. Near-infrared spectroscopy (NIRS) …

The impact of cardiac feedback on human cognition
Afferent feedback from arterial baroreceptors modulates sensorimotor responses, but it is unknown whether it can also interfere with high-order cognition. In Study One, electrocutaneous stimuli (ranging from non-painful to very painful) were randomly delivered across the cardiac cycle. Pain ratings …

Role of the Baroreflex in Long-Term Blood Pressure Regulation in Children Born With Very Low Birth Weight
<bold>INTRODUCTION:</bold> Children born preterm and with very low birth weight are at increased risk of developing elevated blood pressure (BP) later in life. One mechanism of short-term BP regulation is the baroreflex, which can be assessed by calculating baroreflex sensitivity (BRS). There is …

The role of renal afferent signalling in chronic intermittent hypoxia-induced sympathoexcitation and hypertension
… sensory inputs from high- and low-pressure baroreceptors. Blunted baroreflex control of renal sympathetic nerve activity (RSNA) was revealed in hypertension models that involve renal inflammation. Suppression of inflammation restored the normal baroreflex control of RSNA in some of these …

Investigation Of Whether Sedentary And Physically Active Conditions Lead To Altered Gabaergic Signaling In The Rvlm
… response to GABA may be due the arterial baroreceptors buffering the actions of GABA through the contralateral RVLM. Once we inhibit the contralateral RVLM then we are able to see differences. Since the arterial baroreceptor reflex provides tonic GABAergic input to RVLM, we wanted to know …
