Arterial Baroreflex Regulation of Sympathetic Discharge During Maximal Voluntary End-Inspiratory Apnea
… to maintain blood pressure (BP) homeostasis. The arterial baroreflex represents a critical mechanism regulating sympathetic outflow during rest and physiological stress. Volitional apnea, seen in breath-hold diving, serves as a physiological stressor and a model to increase sympathetic outflow in …

Identifying a low-order beat-to-beat model of arterial baroreflex action
The arterial baroreflex is a fast-acting control mechanism that the body relies on to regulate blood pressure. Previous efforts to quantitatively model the baroreflex have relied primarily on non-parametric characterization of the transfer function from blood pressure to heart rate (Berger et …

Muscle Metaboreflex And Arterial Baroreflex: Action, Interaction And Altered Control In Heart Failure
… submaximal exercise induces large increases in arterial pressure, cardiac output, heart rate and ventricular contractility however, the vascular responses have varied in previous studies. We addressed three specific questions: 1) what are the mechanism(s) regulating the non-ischemic vasculature …

Tracking autonomic balance using open and closed loop models of the arterial baroreflex
The arterial baroreceptor reflex is the major blood pressure control loop mediated by the autonomic nervous system (ANS). It supports arterial blood pressure homeostasis by dynamically adjusting heart rate, vascular resistance, venous tone, and cardiac contractility. Accurate quantitative models of …

A role for insulin in the central control of sympathetic nerve activity in humans
… modulatory role for insulin in the regulation of arterial baroreflex control of sympathetic nerve activity. The experiments within this dissertation were designed to further the understanding of insulin's role in modulating central sympathetic outflow in humans. The data presented demonstrate that …

Mechanisms Mediating Modulation Of The Cardiopulmonary Chemoreflex Control Of Regional Sympathetic Outputs By Adenosine A1 And A2a Receptors In The Nts
… A<sub>1</sub> adenosine receptors inhibit the arterial baroreflex whereas A<sub>2a</sub> receptors do not reset baroreflex control of regional sympathetic outputs, although stimulation of these receptors decreases renal (RSNA) increases preganglionic adrenal (pre-ASNA) and does not alter lumbar …

Longterm peripheral baroreflex and chemoreflex function after bilateral eversion carotid endarterectomy
… to assess the long-term effect of the e-CEA on arterial baroreflex and peripheral chemoreflex function in humans. Methods A retrospective review was conducted on a prospectively compiled computerized database of 3128 CEAs performed on 2617 patients at our Center between January 2001 and March …
