Application of Numerical Noise Titration during Autonomic Blockade
"... The influence of pharmacological autonomic nervous system interventions on nonlinear cardiovascular regulatory indices is nowadays still not clear. The present study assesses the effects of autonomic blockade (α- and β-adrenoceptor and cholinergic) on cardiovascular function by heart rate variabilit ..."

The influence of pharmacological autonomic nervous system interventions on nonlinear cardiovascular regulatory indices is nowadays still not clear. The present study assesses the effects of autonomic blockade (α- and β-adrenoceptor and cholinergic) on cardiovascular function by heart rate
Selective Quantification of Cardiac Sympathetic and Parasympathetic Nervous Function Based on the Heart Rate Baroreflex Impulse Response
"... We introduce an improved technique for selectively quantifying cardiac sympathetic and parasympathetic nervous function based on the identification of the heart rate (HR) baroreflex impulse response from non-invasive cardio-respiratory measurements. We have tested the technique with respect to 24 hu ..."

Nonlinear Analysis of the Cardiorespiratory Coordination in a Newborn Piglet
, 1997
"... . We investigate the cardiorespiratory system of a newborn piglet during REM and NON--REM sleep as well as general anesthesia, hypoxia, and cholinergic blockade. The coordinated behavior of heart rate fluctuation and respiratory movement reflects essential capabilities of the autonomic coordination. ..."

Effect of Autonomic Blockers on Heart Period Variability in Calves: Evaluation of the Sympatho-Vagal Balance
, 2001
"... This study was designed to validate the measures of heart period variability for assessing of autonomic nervous system control in calves. Eight calves received an injection of either 0.5 mg/kg atenolol (sympathetic tone blockade), 0.2 mg/kg atropine sulfate (parasympathetic tone blockade), 0.5 mg/kg ..."

Perturbation in Parasympathetic Nervous System Activity Affects Temporal Structure of Poincaré Plot
"... Abstract A novel descriptor (Complex Correlation Measure (CCM)) for measuring the variability in the temporal structure of Poincaré plot has been developed to characterize or distinguish between Poincaré plots with similar shapes. This study was designed to assess the changes in temporal structure ..."

plot is modulated by the parasympathetic activity which correlates with changes in CCM values. Introduction Heart rate variability (HRV) is one of the powerful noninvasive method for analyzing the function of the autonomic nervous system. It is useful to understand the interplay between the sympathetic
Multivariate pattern classification reveals autonomic and experiential representations of discrete emotions. Emotion. Epub ahead of print. doi
, 2013
"... Defining the structural organization of emotions is a central unresolved question in affective science. In particular, the extent to which autonomic nervous system activity signifies distinct affective states remains controversial. Most prior research on this topic has used univariate statistical a ..."

data were processed using heart rate variability software (Acharya, Joseph, These 16 autonomic measures were adjusted to reflect relative change from the washout preceding the trial by subtracting the mean value of the 60 s prior to the end of the emotion induction from the last 60 s of the preceding
HRV Biofeedback in Neck Pain Effects of Heart Rate Variability Biofeedback in Subjects with Stress-related Chronic Neck Pain: a Pilot study
"... Abstract Recent studies focusing on autonomic nervous system (ANS) dysfunctions, together with theoretical pathophysiological models of musculoskeletal disorders, indicate the involvement of ANS regulation in development and maintenance of chronic muscle pain. Research has demonstrated the effectiv ..."

the effectiveness of heart rate variability (HRV) biofeedback (BF) in increasing HRV and reducing the symptoms of different disorders characterized by ANS aberration. The study investigated the effects of resonance frequency HRV BF on autonomic regulation and perceived health, pain, stress and disability in 24
—Original— Effect of Post-Weaning Individual Housing on Autonomic Responses in Male Rats to Sexually Receptive Female Rats
"... Abstract: Post-weaning individual housing induces significant alterations in the reward system of adult male rats presented with sexually receptive female rats. In this study, we examined the effects of post-weaning individual housing on autonomic nervous activity in adult male rats during encounter ..."

, 2004
"... A meta-analysis of 95 studies was conducted to investigate the relations of heart rate (HR) and electrodermal activity (EDA) with aggression, psychopathy, and conduct problems. Analyses revealed a complex constellation of interactive effects, with a failure in some cases of autonomic patterns to ge ..."

The Role of α7 Nicotinic Acetylcholine Receptor in Modulation of Heart Rate Dynamics in Endotoxemic Rats
"... Previous reports have indicated that artificial stimulation of the vagus nerve reduces systemic inflammation in experimental models of sepsis. This phenomenon is a part of a broader cholinergic anti-inflammatory pathway which activates the vagus nerve to modulate inflammation through activation of a ..."
