The central nervous system, comprised of the brain, spinal cord, and nerves, includes the autonomic nervous system (ANS) that regulates involuntary functions. Within the ANS, the sympathetic and the p...
Parasympathetic nervous system innervates peripheral organs including pancreas, hepatic portal system, and gastrointestinal tract. It thereby contributes to the regulation of whole-body glucose metabo...
Autonomic nerves control organ function through the sympathetic and parasympathetic branches, which have opposite effects. In the bone marrow, sympathetic (adrenergic) nerves promote hematopoiesis; ho...
Autonomic imbalance reflected by higher resting heart rate and reduced parasympathetic tone may be driven by low-grade inflammation (LGI) and impaired glycemic control in type 2 diabetes mellitus (T2D...
A large body of work has established the prominent roles of the atrial M2R-IKACh signaling pathway, and the negative regulatory protein RGS6, in modulating critical aspects of parasympathetic influenc...
Context Although the pupil light reflex has been widely used as a clinical diagnostic tool for autonomic nervous system dysfunction, there is no systematic review available to summarize the evidence t...
If we observe an animal being chased by a predator, after the long pursuit, if the animal runs free, we may notice their body physically quiver to reset their nervous system. The ability to literally ...
In this study, we aimed to compare the effects of remimazolam and propofol on parasympathetic activity during general anesthesia induction in patients with
Germline mutations in the succinate dehydrogenase A, B, C, and D genes (collectively, SDHx) predispose to the development of paragangliomas (PGLs) arising at the parasympathetic or sympathetic neuroen...
The parasympathetic nervous system (PNS) has been implicated in the development of visually induced motion sickness. The objective of this study was to per
Acetylcholine signaling by the parasympathetic nervous system is crucial for proper insulin release. Alejandro Caicedo and his colleagues now show that such cholinergic signaling in human pancreatic i...
Recent studies demonstrated a critical functional connection between the autonomic (sympathetic and parasympathetic) nervous and the immune systems. The carotid sinus nerve (CSN) conveys electrical si...
If we observe an animal being chased by a predator, after the long pursuit, if the animal runs free, we may notice their body physically quiver to reset their nervous system. The ability to literally ...
Your parasympathetic nervous system is the network of nerves behind your body’s “rest-and-digest” processes. It runs your body systems when you feel calm and safe.
Heart rate variability (HRV) is an important biomarker for parasympathetic function and future health outcomes. The present study examined how the structur
The autonomic nervous system (ANS) regulates tissue homeostasis and remodelling through antagonistic effects of noradrenergic sympathetic and cholinergic parasympathetic signalling. Despite numerous r...
Schizophrenia (SCZ) is a psychiatric disorder characterized by a wide range of positive, negative and cognitive symptoms, along with an increased risk of metabolic syndrome and cardiovascular disease ...
The present study examined resting heart rate variability (HRV; an index of parasympathetic tone) and heart rate response to the Valsalva maneuver (Valsalv
(often misspelled “vagnus nerve”) Definition The vagus nerve (cranial nerve X) is the primary bi-directional communication channel between the brain and the body’s major organs. It governs parasympath...
