Patterns of sodium excretion during sympathetic nervous system arousal.

Patterns of sodium excretion during sympathetic nervous system arousal.

The purpose of this study was to examine Na+ handling and regulation during 1 hour of behaviorally induced sympathetic nervous system (SNS) arousal followed by 2 hours of recovery. Two patterns of response were observed among experimental subjects, despite similar changes in blood pressure and heart rate. In one group (n = 19), Na+ excretion increased significantly during SNS arousal, which the...

Sympathetic nervous system activity and female sexual arousal.

The results of a series of human and animal studies that were conducted in an effort to better understand autonomic nervous system influences on female sexual arousal are presented. The effects of sympathetic nervous system (SNS) activation on self-report and vaginal photoplethysmographic measures of sexual arousal were examined in 4 studies using intense acute exercise, and in 1 study using ep...

Autonomic Nervous System Influences: The Role of the Sympathetic Nervous System in Female Sexual Arousal

TrkB/BDNF signalling patterns the sympathetic nervous system

The sympathetic nervous system is essential for maintaining mammalian homeostasis. How this intricately connected network, composed of preganglionic neurons that reside in the spinal cord and post-ganglionic neurons that comprise a chain of vertebral sympathetic ganglia, arises developmentally is incompletely understood. This problem is especially complex given the vertebral chain of sympatheti...

Sympathetic nervous system neuroplasticity.

In human and experimental models of heart failure there is widespread change in the sympathetic nervous system. This involves preferential activation of the sympathetic nervous outflow to the heart, impairment of norepinephrine reuptake by sympathetic nerves, and reduction of the content of norepinephrine in the failing myocardium, attributable in part to sympathetic neuronal rarefaction.1–4 Mi...
