Stauss, Harald M., Jens-Ulrich Stegmann, Pontus B. Persson and Heinz-Joachim Häbler. Frequency response characteristics of sympathetic transmission to skin vascular smooth muscles in rats. Am. J. Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R591–R600, 1999.—Sympathetic modulation of cutaneous vasomotor waves in humans is most effective at frequencies up to 0.1 Hz. In contrast, sympa...

Abstract Background Myeloma bone disease (MBD) is a common complication that significantly contributes to morbidity and mortality in multiple myeloma (MM). Serum sclerostin level sympathetic activity can affect MBD. The purpose of this study evaluation serum (using skin response “SSR”) MM patients, studying the relationship between both them as well their with 35 smoldering patients (group I) n...

A microneurographic technique was used to record multiunit sympathetic activity in skin and muscle nerves of 24 healthy subjects and 21 hypertensive subjects. In both groups, the sympathetic activity recorded during rest appeared in bursts following one of two highly different temporal patterns—one characteristic for muscle nerves and the other characteristic for skin nerves. Muscle nerve sympa...

Peripheral blood flow at finger tips is influenced by temperature changes and sympathetic activities. Changes in the local temperature of the skin can produce a localized vasoconstriction that can decrease the skin blood flow essentially to zero. Cold exposure test is used to assess vasoconstrictive responses that results from both the local response and the reflex response of skin microcircula...

Background: Irritable bowel syndrome (IBS) is associated with increased psychological symptoms, early life stressors, and alterations in visceral perception and brain responses to noxious visceral stimuli. The autonomic nervous system (ANS) is a likely mediator for these brain-gut interactions. The few studies directly examining ANS measures have been suggestive of alterations in some IBS patie...

THE relation of the cerebral cortex to the activity of the sympathetic nervous system is not yet fully clear. The clinical and experimental observations, which have recently been reviewed by Kennard (1937), have been conflicting, and there have been few quantitative determinations of the effects of cortical stimulation and ablation upon the functions of the human sympathetic nervous system. Man...

This Synthesis highlights a series of recent studies that has systematically interrogated age-related deficits in cold-induced skin vasoconstriction. In response to cold stress, a reflex increase in sympathetic nervous system activity mediates reductions in skin blood flow. Reflex vasoconstriction during cold exposure is markedly impaired in aged skin, contributing to the relative inability of ...

BACKGROUND Young patients with anxiety disorders are thought to have a hypersensitive fear system, including alterations of the early sensorimotor processing of threatening information. However, there is equivocal support in auditory blink response studies for an enlarged auditory startle reflex (ASR) in such patients. We sought to investigate the ASR measured over multiple muscles (whole-body)...
