Summary: Assessment of heartbeat dynamics can be used for non-invasive monitoring of cardiovascular and autonomic states. However, the non-specificity of such measurements limits their applicability in naturalistic conditions. In this study, we investigate the irregularity and complexity of cardiac sympathetic and vagal activity series in different populations. Our results show significant differences between pathological/old subjects and young subjects, providing new insights into physiology and improving the specificity of heartbeat-derived biomarkers.

Summary: The study aimed to define the spatial organization of intrathoracic parasympathetic and sympathetic efferent projections to the heart. The majority of parasympathetic and sympathetic cardiac-evoked responses were mitigated after debranching of the right vagosympathetic trunk (VST) rostral to heart. These findings contribute to the implementation of targeted neuromodulation-based therapeutics for the treatment of cardiac disease.

Summary: Parental socialization may influence the development of children's autonomic nervous system, particularly the parasympathetic nervous system. A meta-analysis revealed that positive parenting is positively associated with higher resting parasympathetic nervous system activity in children. This association is more pronounced in experimental studies and when the sample includes children with a clinical condition.

Summary: Overall autonomic imbalance, decreased parasympathetic activity, and recently increased sympathetic activity may increase the risk of nonalcoholic fatty liver disease (NAFLD) according to heart rate variability evaluation.

Summary: This study examined the effects of urban environments on the Autonomic Nervous System (ANS) and found that the effects of green areas are immediate, while those of urban environments are gradual. There are ethnic differences in the ANS adaptation among Arab and Jewish women in different environments.

Summary: This article introduces the composition and functions of the autonomic nervous system (ANS) and describes its role in stress and maladaptation. By studying the neuroanatomy of the ANS, a model is proposed to understand its importance in maintaining health and causing diseases.

Summary: The study aimed to investigate the sex-specific effects of capsaicin on cardiac autonomic nervous system (ANS) activity. The results revealed that capsaicin had a promoting effect on ANS activity in males, while it had an inhibitory effect in females. This difference may be due to varying sensitivity of the transient receptor potential vanilloid channel-1 (TRPV1) afferents, and should be further explored in future studies.

Summary: Studies show that the autonomic nervous system has a significant impact on overall health. In modern societies, an unhealthy lifestyle contributes to dysfunction in this system. While physical exercise has well-known positive effects on health, its negative impact needs to be studied further.

Summary: This study measured ECG signals of mouse fetuses to evaluate the development of heart rate and autonomic nervous activity at different stages, finding that fetal heart rate significantly increased at E18.5, accompanied by reduced parasympathetic activity. It suggests that parasympathetic activity rather than sympathetic activity affects fetal heart rate, and the decrease in parasympathetic activity towards the end of pregnancy could lead to the observed increase in fetal heart rate.

Summary: This article summarizes the autonomic disorders and possible mechanisms associated with narcolepsy type 1, which include non-dipping blood pressure, reduced heart rate variability, impaired cerebral autoregulation, reduced gastric motility and emptying, sleep-related erectile dysfunction, skin temperature abnormalities, and blunted pupillary light reflex.

Summary: The study aimed to investigate the applicability of heart rate variability indices in determining the second ventilatory threshold (VT2), with results showing a significant correlation between ECG-derived respiration and high frequency product with VT2. The findings suggest that both high frequency product and ECG-derived respiration are reliable methods for assessing VT2 in a field shuttle run test.

Summary: The autonomic nervous system (ANS) is crucial for stress reactivity, adaptive responses, and health. The central ANS activity relies on the central autonomic network (CAN), while the peripheral activity relies on the sympathetic and parasympathetic nervous systems. The computerized analysis of heart rate variability (HRV) is a widely used method for assessing ANS activity.

Summary: This study assessed the influence of Alzheimer's disease on baroreflex function using an animal model. The results showed that the sympathetic nervous system was primarily affected, which may correlate with orthostatic hypotension in human Alzheimer's disease.

Summary: The lateral habenula regulates autonomic cardiovascular responses through activation of different neural pathways including cardiac parasympathetic nerves and cardiovascular sympathetic nerves. The stimulation effects of lateral habenula are likely mediated by 5-HT1A and 5-HT2 receptors, while other 5-HT receptors do not affect its actions.

Summary: Cardiovascular autonomic neuropathy (CAN) is a debilitating microvascular complication that primarily affects long-standing type 2 diabetes patients but can also manifest early in the disease progression. The pathophysiology of CAN is complex, involving various risk factors and clinical complications, and early identification and treatment of CAN may help reduce mortality rates for affected individuals.

Summary: The study used quantitative magnetic resonance imaging to examine asymmetries in language regions in the human brain, finding that different areas show leftward or rightward lateralization in terms of macromolecular tissue volume. The leftward lateralization of myelination structure was significantly correlated with language skills, suggesting the need for a general theory to explain human hemispheric specialization.
