Vagal Integration of Cardiopulmonary Regulation
… linked with mechanosensitive SARs via a common vagal afferent population by assessing the impact of: i) chemostimulation (10% O2 or 10% CO2); ii) pharmacologic blockade (serotonergic - tropisetron or purinergic-suramin); and iii) loss of the calcium-sensing receptor (CaSR) on quasi-static SAR …

Endocannabinoid regulation of gastric vagal afferent signalling
Background: Gastric vagal afferents (GVAs) play a role in peripheral appetite control. Tension sensitive GVAs respond to stretch or distension of the stomach sending signals to the hindbrain to produce feelings of fullness and satiety. The sensitivity of tension sensitive GVAs is reduced in …

Modulation of mechanosensitive gastro-oesophageal vagal afferents by novel targets.
Modulation of signals from peripheral vagal afferent mechanoreceptors to the central nervous system has been identified as the most accessible target for control of neuronal pathways and reflexes central to gastrointestinal disorders such as GORD, disordered food intake and functional dyspepsia. …

Vagal tone and depression in adolescents: Protective factors during parent-adolescent interaction
Vagal tone, an index of emotion regulation, is related to a number of mental health outcomes in youth, including depressive risk and symptomology. The current study examined the role that vagal tone, as measured by respiratory sinus arrhythmia (RSA) at rest and during emotionally relevant …

Parenting and internalizing symptoms in early adolescence: The moderating role of vagal tone
The present study investigated baseline respiratory sinus arrhythmia (RSA) as moderator of the prospective association between parenting and internalizing symptoms among a group of typically developing adolescents across the transition to middle school. At Time 1 (5th grade; spring before middle …

The contribution of coping related variables and cardiac vagal activity on performance under pressure.
… parasympathetic nervous system, termed cardiac vagal activity, is a marker of self-regulation as theorised by the neurovisceral integration model (Thayer et al. 2009). This psychophysiological marker has been shown to be sensitive to pressure and help facilitate performance in pressurised …

RDH10 is Necessary for Initial Vagal Neural Crest Cell Contribution to Embryonic Gastrointestinal Tract Development
… rather is necessary as a paracrine signal in the vagal NCC microenvironment. We investigated signaling cascades that are known to play a role in gut microenvironment maintenance that may be altered in these RDH10 mutants using both a targeted expression analysis approach as well as RNA-sequencing. …

Effects of Aquatic Therapy on Vagal Tone and Social Behaviors in Individuals with Autism Spectrum Disorder
… study evaluated the effect of aquatic therapy on vagal tone as well as behavior in participants with ASD (n=32) and without ASD (n=32). Measures consisted of social, swimming, emotional and cognitive tasks. Following the aquatic intervention participants with ASD demonstrated a statistically …

Working Memory Load Under Anxiety: Quadratic Relations to Cardiac Vagal Control and Inhibition of Distractor Interference
… (WM) with non-affective information. Cardiac vagal control has been related to emotion regulation and may serve as a proxy for load-related inhibition under anxiety (Thayer and Lane, 2009). The present study examined whether: (1) the enhancing and impairing effects of load on inhibition exist …

The Role of Cardiac Vagal Tone in Prediction of Individual Differences in Attention and Emotion Processing After Sleep Restriction
… laden visual stimuli were examined. The role of vagal tone, indexed by Respiratory Sinus Arrhythmia (RSA), was examined as a trait-like individual difference variable for prediction of vulnerability to sleep loss. Healthy, good sleepers between the ages of 17-30 were recruited from a university …

Individual differences in affect and vagal tone in response to moderate- and high-intensity interval exercise: A preliminary model
… engagement. Purpose. To examine affective and vagal tone reactivity to and recovery from an acute bout of moderate-intensity (MIIE) and high-intensity interval exercise (HIIE), and to consider how individual differences (e.g., personality, biological dispositions) influence these responses. …

Smooth Muscle-Specific Removal of Brain-Derived Neurotrophic Factor Results in Increased Vagal Afferent Innervation to the Intestine and Increased Satiation in Mice
<p>Vagal afferents transmit signals regarding food-derived stimuli in the gastrointestinal (GI) tract to the brain. Vagal mechanoreceptors called intraganglionic laminar endings (IGLEs) innervate the smooth muscle wall of GI organs and detect stretch and tension to regulate GI reflexes and …

Naᵥ1.8+ Visceral Afferent Neurons: Roles in Metabolism and Inflammation
… a network of inflammatory signaling pathways. As vagal afferents are a neuronal population that can rapidly respond to both food-related stimuli as well as inflammatory agents and cytokines, I hypothesized that intact vagal afferent function may be required for proper regulation of energy balance …

Marital Harmony and Conflict: Linkages to Infants' Emotional Regulation, Cardiac Vagal Tone, and Developmental Status at Six- and Nine-Months of Age
This study examined the linkages between marital harmony and conflict and infants' emotional and physiological regulation abilities and developmental status at six- and nine-months of age. Participants included 93 first-time mothers and their infants (43 males, 50 females) from a Mountain West …

Central Stimulation of the Vagi and Gastric Secretion
… conducting the impulses were located in the vagal trunk. | After the discovery, isolation and purefication of insulin by Banting and Best in 1922 (2), its physiological and pharmacological effects were studied by a multitude of workers. The gastric secretory effect of insulin hypoglycemia was …

Peripheral and Central Muscarinic Cholinergic Receptors in Arterial Blood Pressure Regulation
