Lateralized Induction of Cardiovascular Responses: Exploring Asymmetric Autonomic Regulation
There is clear evidence that the autonomic nervous system (ANS) is lateralized at both the peripheral as well as the central levels of the nervous system. Both the vagus and the sympathetic ganglia asymmetrically innervate the sino-atrial node and the myocardium of the heart. This lateralization …

Physiological and psychological measurements during cognitive stress : comparing the effectiveness of two stress intervention techniques.
… health. Work related stress has an effect on the autonomic nervous system and hence also can affect heart rate. By studying heart rate variability we can indirectly observe autonomic regulation in a convenient, non-invasive manner. Greater autonomic control and HRV are beneficial for managing work …

Examining empathy in Autism Spectrum Disorders: cognitive, subjective and physiological correlates of the perception of pain
… others' mental states (cognitive empathy), and regulation of one's own emotional state (self-regulation). Empathy can also lead to muscle mimicry and empathic concern for another's wellbeing. I argue that empathy should be measured on multiple levels: cognitive, subjective and physiological. …

Cortical and autonomic modulation of attentional control /
… work has been done on the role of the ACC in autonomic regulation. Its connections through the vagus nerve to the sinoatrial node of the heart are thought to exert modulatory control over cardiovascular arousal. Therefore, ACC is not only responsible for the implementation of cognitive …

Heart rate variability in mice with coronary heart disease
… rate, is a non-invasive test that measures the autonomic regulation of the heart. Assessment of HRV has been shown to predict the risk of mortality in patients after an acute myocardial infarction. Recently, the Krieger lab at MIT developed genetically engineered double knockout (dKO) mice that …

Resiliency and Autonomic Control of Cardiac Responses to Stress
… cardiovascular responding without accounting for autonomic nervous system origins of physiological responses. Similarly, EC tends to be associated with increased cardiac vagal control. However, differences in the autonomic characteristics of these constructs remain unclear. In the current study, …

Sleep under stress: the complex web of fear, hypervigilance and mental health in a low socioeconomic status community in South Africa
… which can be quantified through measures of autonomic nervous system function, such as heart rate variability. Heart rate variability (HRV) is a non-invasive measure of autonomic regulation of the heart which can be divided into time and frequency domain variables. Frequency domain variables …

Comparison of five oral cannabidiol preparations in adult humans: pharmacokinetics, body composition, and heart rate variability
… CBD ingestion may have a modest influence on autonomic regulation of heart rate.

Neural adaptive mechanisms in respiratory regulation : theory and experiments
… A more complete understanding of respiratory regulation necessitates better knowledge of these underling brain mechanisms. While the task of breathing may seem straightforward, the respiratory system faces many challenges that threaten to perturb homeostasis. It has been shown that the …

METABOLIC IMPROVEMENT AFTER EXERCISE TRAINING IN CHILDREN WITH OBESITY: POSSIBLE ROLE OF THE SIX-MINUTE WALKING TEST
… hours and quality, health perception), Cardiac Autonomic Regulation (CAR). Spearman correlations between the variations in the studied outcomes were explored. Results: After intervention, the distance covered during 6MWT significantly increased (p <0.001), and nutrition quality improved slightly …

Evidence for effects of phoenixin on neurons of the paraventricular nucleus
… (PVN) of the hypothalamus has been implicated in autonomic regulation. Through projections to the pituitary gland, median eminence and hindbrain, the PVN plays a role in stress response and other autonomic functions. Recent findings have indicated that both phoenixin (PNX), a peptide involved in …

Right Hemisphere Activation to Rotary Stress in High and Low Hostile Men
… high and low hostile men differ with respect to autonomic regulation of stress. The functional cerebral systems approach has provided a theoretical framework to account for this finding across the individual sensory, motor, and premotor modalities. The current experiment extends and elaborates …

CARDIAC AUTONOMIC CONTROL DURING SLEEP IN PATIENTS WITH MULTIPLE SYSTEM ATROPHY: A PILOT STUDY ON THE IMPACT OF CPAP THERAPY
Objectives To characterize sleep-stage autonomic regulation in multiple system atrophy (MSA) using cardiorespiratory coupling (K2) and symbolic dynamics (0V%, 2UV%, 2LV%) derived from ECG tracings in video‐polysomnography (v‐PSG). The study aims to compare patients with and without sleep‐disordered …

Functional MRI Investigation of the Neural Basis of Human Pain Processing in the Brainstem and Spinal Cord; Descending Regulation and Chronic Pain
… established brainstem and spinal cord pain regulation and resting-state networks, and then compare this to data from groups with fibromyalgia (FM) and provoked vestibulodynia (PVD). FM and PVD are two chronic pain conditions disproportionately affecting women, the underlying mechanisms of …

Cardiac Autonomic Assessment and Diastolic Function in Individuals with Spinal Cord Injury
… index (QTVI) as a measure of cardiac autonomic function in individuals with spinal cord injury (SCI). The secondary purpose was to investigate the influence of cardiac autonomic activity and blood volume on diastolic function in individuals with SCI. Results from Study 1 showed that …

Phenotyping Behavioral Disorders in REM Sleep: Study of Digital Biomarkers of Neurodegeneration
… early-stage biomarkers and understanding autonomic dysfunction in RBD. Heart Rate Variability (HRV) and QT Variability (QTV), studied across different sleep stages, were investigated as potential digital biomarkers of neurodegeneration. Apart from traditional HRV analysis, this thesis also …
