Relative Roles of the Sympathetic and Parasympathetic Nervous Systems in the Reflex Control of Heart Rate.
• Since the work of Marey in 1859, it has been known that as arterial pressure is changed acutely, heart rate varies in an inverse fashion. Moreover, it is firmly established that the afferent impulses of this reflex originate from baroreceptors in the cardiovascular system, primarily those in the carotid sinus and in the aortic arch areas.' The precise definition of the efferent arm of the ref...
متن کاملFacial Vibrotactile Stimulation Activates the Parasympathetic Nervous System: Study of Salivary Secretion, Heart Rate, Pupillary Reflex, and Functional Near-Infrared Spectroscopy Activity
We previously found that the greatest salivation response in healthy human subjects is produced by facial vibrotactile stimulation of 89 Hz frequency with 1.9 μ m amplitude (89 Hz-S), as reported by Hiraba et al. (2012, 20011, and 2008). We assessed relationships between the blood flow to brain via functional near-infrared spectroscopy (fNIRS) in the frontal cortex and autonomic parameters. We ...
متن کاملReflex heart rate control in asthma. Evidence of parasympathetic overactivity.
The bronchial hyperreactivity characteristic of asthma may be related to enhanced parasympathetic nervous activity. We postulated that an abnormality in the autonomic control of airway caliber might be reflected by a parallel change in the reflex control of heart rate. We examined the heart-rate variations induced by deep breathing (respiratory sinus arrhythmia), the Valsalva maneuver, and stan...
متن کاملRelative roles of sympathetic and parasympathetic nervous systems in the carotid sinus reflex in dogs.
The effects of electrical stimulation of the carotid sinus on sinus rate and atrioventricular (A-V) conduction were studied before and after alternate interruption of the vagi and sympathetic nerves to the heart in dogs. In group I, carotid sinus stimulation caused a similar absolute decrease in sinus rate before and after vagotomy, although after vagotomy the response was more latent. Subseque...
متن کاملParasympathetic reflex vasodilatation in rat submandibular gland.
The present study was designed to investigate 1) whether parasympathetic reflex vasodilatation occurs in the submandibular gland (SMG) in deeply urethan-anesthetized, cervically vagotomized, and sympathectomized rats when the central cut end of the lingual nerve (LN) is electrically stimulated and 2) to what extent the neural mechanisms underlying such responses are the same as those involved i...
