The Diurnal Profile of Human Basal Pain Sensitivity and Skin Sympathetic Nerve Activity: A Healthy Volunteer Study

Frontiers in Neuroscience, 2022
ObjectiveThe diurnal rhythm profile of human basal pain sensitivity and its association with sympathetic nerve activity are not fully understood. This study aimed to examine rhythmic changes in experimental pain sensitivity and skin sympathetic nerve ...

Oscillatory Pattern of Sympathetic Nerve Bursts Is Associated With Baroreflex Function in Heart Failure Patients With Reduced Ejection Fraction

Frontiers in Neuroscience, 2021
Sympathetic hyperactivation and baroreflex dysfunction are hallmarks of heart failure with reduced ejection fraction (HFrEF). However, it is unknown whether the progressive loss of phasic activity of sympathetic nerve bursts is associated with baroreflex

Direct evidences for sympathetic hyperactivity and baroreflex impairment in Tako Tsubo cardiopathy. [PDF]

PLoS ONE, 2014
BackgroundThe exact pathophysiology of Tako-Tsubo cardiomyopathy (TTC) remains unknown but a role for sympathetic hyperactivity has been suggested. Up to now, no direct evidence of sympathetic nerve hyperactivity has been established nor involvement of ...

Cardiovascular and Metabolic Crosstalk in the Brain: Leptin and Resistin

Frontiers in Physiology, 2021
Leptin and resistin are cytokines whose plasma levels correlate with adiposity. Leptin is a hormone synthesised and released from adipocytes and can be transported into the brain. Resistin is produced in adipocytes in rodents and in macrophages in humans,

Characterizing sympathetic neurovascular transduction in humans. [PDF]

PLoS ONE, 2013
Despite its critical role for cardiovascular homeostasis in humans, only a few studies have directly probed the transduction of sympathetic nerve activity to regional vascular responses--sympathetic neurovascular transduction.

Autonomic Modulation of Atrial Fibrillation

JACC: Basic to Translational Science, 2023
Summary: The autonomic nervous system plays a vital role in cardiac arrhythmias, including atrial fibrillation (AF). Therefore, reducing the sympathetic tone via neuromodulation methods may be helpful in AF control. Myocardial ischemia is associated with

Organ-Specific Activation of the Gastric Branch of the Efferent Vagus Nerve by Ghrelin in Urethane-Anesthetized Rats

Journal of Pharmacological Sciences, 2014
.: Ghrelin plays multiple physiological roles such as growth hormone secretion and exerting orexigenic actions; however, its physiological roles in the electrical activity of autonomic nerves remain unclear.
