Role of the Sympathetic Nervous System and Its Modulation in Renal Hypertension
Frontiers in Medicine, 2018 The kidneys are densely innervated with renal efferent and afferent nerves to communicate with the central nervous system. Innervation of major structural components of the kidneys, such as blood vessels, tubules, the pelvis, and glomeruli, forms a ...

Alterations in electrodermal activity and cardiac parasympathetic tone during hypnosis [PDF]
, 2015 Exploring autonomic nervous system (ANS) changes during hypnosis is critical for understanding the nature and extent of the hypnotic phenomenon and for identifying the mechanisms underlying the effects of hypnosis in different medical conditions.

Neuraxial modulation for treatment of VT storm. [PDF]
, 2014 In the hyperadrenergic state of VT storm where shocks are psychologically and physiologically traumatizing, suppression of sympathetic outflow from the organ level of the heart up to higher braincenters plays a significant role in reducing the propensity

Macaque cardiac physiology is sensitive to the valence of passively viewed sensory stimuli. [PDF]
, 2013 Autonomic nervous system activity is an important component of affective experience. We demonstrate in the rhesus monkey that both the sympathetic and parasympathetic branches of the autonomic nervous system respond differentially to the affective ...

Semi-automated Model to Accurately Counting Sympathetic Nervous Fibers
Bio-Protocol, 2019 In recent years, the role of sympathetic nervous fibers in chronic inflammation has become increasingly evident. At the onset of inflammation, sympathetic activity is increased in the affected tissue.

A cholinergic-sympathetic pathway primes immunity in hypertension and mediates brain-to-spleen communication [PDF]
, 2016 The crucial role of the immune system in hypertension is now widely recognized. We previously reported that hypertensive challenges couple the nervous drive with immune system activation, but the physiological and molecular mechanisms of this connection ...

HIF-1α is required for development of the sympathetic nervous system
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance The sympathetic nervous system plays a critical role in stimulating heart rate and contractility to increase cardiac output and thereby insure adequate tissue O2 delivery.

Time Series Analysis using Embedding Dimension on Heart Rate Variability [PDF]
, 2018 Heart Rate Variability (HRV) is the measurement sequence with one or more visible variables of an underlying dynamic system, whose state changes with time. In practice, it is difficult to know what variables determine the actual dynamic system.

Autonomic Nervous System Activity During a Speech Task
Frontiers in Neuroscience, 2019 Previous research has reported that different coping types (active or passive) are required depending on the stress-inducing task. The aim of this study was to examine the autonomic nervous response during speech tasks that require active coping, by ...
