The role of inhibitory G proteins and regulators of G protein signaling in the in vivo control of heart rate and predisposition to cardiac arrhythmias [PDF]
, 2012 Inhibitory heterotrimeric G proteins and the control of heart rate. The activation of cell signaling pathways involving inhibitory heterotrimeric G proteins acts to slow the heart rate via modulation of ion channels.

European Journal of Clinical Investigation, 2019 Atrial fibrillation (AF) is the commonest abnormal heart rhythm with significant related morbidity and mortality. Several pathophysiologic mechanisms have been advocated to explain the onset of AF. There has been increasing evidence that abnormalities of

bioRxiv, 2019 Autonomic nervous system (ANS) activity is a core and central component of emotion. The myriad social and cognitive challenges faced by humans require flexible modulation of ANS activity for different contexts. In this study, simultaneous activity of the

Parasympathetic nervous system activity and children's sleep [PDF]
Journal of Sleep Research, 2012 SummaryWe examined indices of children's parasympathetic nervous system activity (PNS), including respiratory sinus arrhythmia during baseline (RSAB) and RSA reactivity (RSAR), to a laboratory challenge, and importantly the interaction between RSAB and RSAR as predictors of multiple parameters of children's sleep.

Variability of the Heart Rhythm as an Additional Marker for Determining Vegetative Functions in Patients with Chronic Cerebral Ischemia [PDF]
, 2018 Aim. Practical cardiology is in constant search for non-invasive vascular risk markers. Heart rhythm reflects the body\u27s response to various stimuli of the external and internal environment. Heart rate variability (HRV) has a prognostic and diagnostic

Lateral Habenula Regulates Cardiovascular Autonomic Responses via the Serotonergic System in Rats
Frontiers in Neuroscience, 2021 The lateral habenula (LHb) plays essential roles in behavioral responses to stressful events. Stress is tightly linked to autonomic responses such as cardiovascular responses, yet how the LHb regulates these responses is not well understood.

TSE pathogenesis in cattle and sheep [PDF]
, 2008 Many studies have been undertaken in rodents to study the pathogenesis of transmissible spongiform encephalopathies (TSE). Only a few studies have focused on the pathogenesis of bovine spongiform encephalopathy (BSE) and scrapie in their natural hosts ...

Heart rate variability and circulating inflammatory markers in midlife
Brain, Behavior, & Immunity - Health, 2021 Theoretical perspectives and empirical evidence suggest that the parasympathetic nervous system engages in active monitoring and moderating of inflammatory processes.

Parasympathetic functions in children with sensory processing disorder. [PDF]
, 2010 The overall goal of this study was to determine if parasympathetic nervous system (PsNS) activity is a significant biomarker of sensory processing difficulties in children. Several studies have demonstrated that PsNS activity is an important regulator of

Parasympathetic nervous system response to acidosis: Evaluation in an experimental fetal sheep model
Acta Obstetricia et Gynecologica Scandinavica, 2019 Heart rate variability and fetal heart rate decelerations are impacted by parasympathetic function and reflect acid‐base status. Our team developed a new heart rate variability index, the fetal stress index (FSI), which has lower interindividual ...
