Effects of sleep deprivation on autonomic nervous system
… events by increasing the sympathetic nervous system activity. The aim of the present study was to evaluate the relationship between sleep deprivation and the autonomic nervous system activity by means of heart rate variability (HRV) and blood pressure variability (BPV). All data were …

Multivariate Discrimination of Emotion-Specific Autonomic Nervous System Activity
The present study investigated autonomic nervous system (ANS) patterning during experimentally manipulated emotion. Film clips previously shown to induce amusement, anger, contentment, disgust, fear, and sadness, in addition to a neutral control, were presented to 34 college-aged subjects while …

Autonomic Nervous System Correlates of Emotion Regulation in Autistic Adults
… has found that emotion regulation strategies and autonomic nervous system (ANS) responses involved in emotion regulation differ between autistic and non-autistic individuals. These findings highlight the role of the ANS as a measure of emotion regulation; however, this has not been studied in an …

Studies on the role of the autonomic nervous system in airway hyperreactivity.
The airway hyperreactivity (AH) characteristic of bronchial asthma has many possible underlying causes. This study focussed on the contribution of K+ -ion channels and Ca2+ - dependent processes to AH, in a guinea-pig model of asthma. Cromakalim, a potassium channel opening drug, attenuated …

Modeled and Unmodeled Approaches for Quantification of the Cardiac Autonomic Nervous System
The autonomic nervous system (ANS) is a branch of the nervous system that regulates involuntary functions within the body, such as blood pressure control (the baroreceptor reflex) and arousal. Tracking ANS activity in patients may provide information about traumatic brain injury, heart failure, …

A model of sinoatrial node cell regulation by the autonomic nervous system
… sympathetic and parasympathetic branches of the autonomic nervous system. Our understanding of sinoatrial node cell function has been greatly advanced by experimental and modeling efforts that quantitatively describe the numerous ionic currents responsible for the cell's spontaneous …

Altered Autonomic Nervous System Function in Chickens Divergently Selected for Body Weight
Autonomic nervous system activity is related to body weight regulation. Based on the MONA LISA hypothesis it has been suggested that most obese subjects and animals have low sympathetic nervous system activity. The aim of this study was to investigate whether there are differences in autonomic …

Relationship between the autonomic nervous system and the recovering heart post exercise using heart rate variability
… relationship exists between the activity of the autonomic nervous system (ANS) and the speed of heart rate recovery post maximal exercise. The parasympathetic branch of the ANS was assessed during rest by obtaining the high frequency (HF) component of the heart rate variability (HRV) frequency …

A Window Into Autonomic Nervous System Functioning in Autism: Pupillometry in Adults on the Autism Spectrum
<p>The autonomic nervous system (ANS) regulates physiological processes throughout the body and disruption or imbalance of that system has been associated with negative physical and psychological outcomes. Pupil responsivity is controlled by the autonomic nervous system and has been show to index …

Cardiovascular and Autonomic Nervous System Function: Impact of Glucose Ingestion, Hydration Status and Exercise in Heated Environments
Cardiovascular function is under the influence of autonomic nervous system, both of which can be assessed non-invasively. The purpose of this dissertation was to examine these non-invasive markers of cardiovascular and autonomic function and their relationships with exercise training, glucose …

Women's of healthy and reproductive age reaction to affective images: researches on subjective evaluations, central and autonomic nervous system /
… and to compare the responses of central and autonomic nervous system. The present dissertation is based on carried out three studies. Based on the results of the first study, it concluded that International Affective Picture System (IAPS) can be used for emotion studies in Lithuanian female. …

Assessment of the autonomic nervous system through the study of cardiovascular autonomic reflexes and their association with inflammation in three clinical settings.
… sympathetic and parasympathetic branches of the Autonomic Nervous System (ANS). Reduced ANS tone measured by reduced heart rate variability (HRV) is a powerful predictor of adverse diagnosis in patients and is associated with increased mortality. Published research suggests that inflammation has …

Do Different Music Genres Differentially Affect Autonomic Activity? How Music and Sound Affect Autonomic Activity Aroused by Visual Stimuli
… music would differentially influence measures of autonomic nervous system activity (heart rate, galvanic skin response) while viewing visual stimuli in a sample of college students. All participants listened to the same songs and music genres and viewed the same International Affective Picture …

Influence of the Autonomic Nervous System, Skin Barrier Indicators and Psycho-Emotional Aspects in Patients with Lichen Simplex Chronikus /// Влияние на вегетативната нервна система, показатели на кожната бариера и психо-емоционални аспекти при пациенти с лихен симплекс хроникус
Лихен симплекс хроникус (ЛСХ) е хронична дерматоза с ограничени, силно сърбящи лихенифицирани и инфилтрирани плаки. Предилекционно те се разполагат по задната и странични участъци на тила, по екстензорните повърхности на тялото и в ано-гениталната област. Заболяването ангажира и двата пола, като …

Putting the Body Back Together: A Functional Autonomic Model of Interoception
… that leverages the integrative nature of the autonomic nervous system. Thirty-four undergraduates provided real-time feedback about their subjective state of arousal while watching three videos of varying intensity. Across subjects, arousal feedback did not positively correlate with …

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 …

Lasting effects of atlanto-axial manipulation on edge light pupil cycle time
… the eye, which is controlled via the automatic nervous system. Studies have shown ELPCT to be a measurable constant, unaffected by visual acuity, refractive error, eye colour, pupil size or gender. Recent studies have shown that high-velocity manipulation of the upper cervical spine causes an …

Investigation of heart rate variability during sleep apnea
… hour. Apnea has strong modulating effects on the autonomic nervous system, with prominent heart rate variation. It can be assumed that during sleep, internal influences (sympathetic and parasympathetic nervous system activities) dominate the autonomic nervous system; in addition repetitive apneas …

Studies on aspects of Autonomic Neuropathy in non Insulin dependent Diabetes
Autonomic neuropathy (AN) is a well-recognized complication of diabetes mellitus. It has multiple clinical features and is often associated with debilitation and an increased mortality. However, there appears to be a paucity of knowledge with regard to its effects on hormone release and its …
