The importance of the central nervous system in the antiarrhythmic actions of diphenyhiydantoin and lidocaine was studied using arrhythmias induced by electrical stimulation of the posterior hypothalamus in cats. Hypothalamic stimulation resulted in cardiac arrhythmias mediated by the sympathetic nervous system. The arrhythmias occurred during stimulation, and recordings from cardiac sympatheti...

The nerves to the cervical and thoracic vertebrae were traced in 10 serially sectioned human embryos. It was found that the vertebral bodies receive nerve fibres from the trunks of the spinal nerves, anterior branches and meningeal branches of the spinal nerves, and from the sympathetic trunks. Slender twigs from the trunk of the spinal nerve arise close to the spinal ganglion and terminate in ...

The left ventricle is richly supplied with sympathetic nerves, which are spatially localized next to cardiac myocytes in a fashion that permits the rapid transmission of autonomic signals via the release of norepinephrine. Previous investigation in the heart has largely focused on the local release and reuptake kinetics of norepinephrine in conjunction with its downstream receptor-mediated even...

AIMS/INTRODUCTION Previously, it was observed that long-term ingestion of a probiotic strain Lactobacillus casei Shirota (LcS) ameliorates insulin resistance and glucose intolerance in rats fed a high-fat diet. In the present study, we examined its possible role in the autonomic nervous system during LcS-induced modulations in glucose and lipid metabolism or cardiovascular functions. MATERIAL...

BACKGROUND AND OBJECTIVES Recent studies showed that, in addition to parasympathetic nerves, cervical vagal nerves contained significant sympathetic nerves. We hypothesized that cervical vagal nerve stimulation (VNS) may capture the sympathetic nerves within the vagal nerve and activate the stellate ganglion. MATERIALS AND METHODS We recorded left stellate ganglion nerve activity (SGNA), left...

The properties and latencies of potentials evoked in cardiac (CN) and renal (RN) sympathetic nerves by electrical stimulation of the sinus, aortic and hypoglossal nerves were studied in cats. Electrical stimulation of the sinus nerve evoked only excitatory responses in the sympathetic nerves. Electrical stimulation of the aortic nerve fibers evoked excitatory or inhibitory responses in sympathe...

Although cerebral blood vessels are densely innervated by sympathetic nerve fibers, the functional significance of the nerves is controversial. Because previous studies have been primarily performed in anesthetized animals, it is possible that failure to observe prominent neural control of the cerebral circulation was secondary to anesthetic-induced depression of the sympathetic nervous system....

Efferent renal sympathetic nerves reinnervate the kidney after renal denervation in animals and humans. Therefore, the long-term reduction in arterial pressure following renal denervation in drug-resistant hypertensive patients has been attributed to lack of afferent renal sensory reinnervation. However, afferent sensory reinnervation of any organ, including the kidney, is an understudied quest...

Autonomic nerves, consisting of both sympathetic and parasympathetic nerves, regulate various bodily functions such as blood pressure, body temperature, glucose metabolism, energy metabolism, and digestion. Our studies in rats and mice have demonstrated that food, flavor, and music affect physiological phenomena via changes in autonomic neurotransmissions. Intestinal injection of Lactobacillus ...
