Summary: This study investigated the prognostic value of heart rate variability (HRV) and skin sympathetic nerve activity (SKNA) in patients with intracerebral hemorrhage (ICH). The results suggest that reduced HRV and SKNA may be indicators of poor neurological outcomes in ICH patients.

Summary: Heart rate asymmetry (HRA) is a physiological phenomenon characterized by an unequal contribution of heart rate decelerations and accelerations to different heart rate variability (HRV) features. This study investigated the variance- and number-based HRA features in 96 healthy children using 24-h ECGs and found that heart rate decelerations contributed more to short-term HRV in boys. The majority of children had some form of HRA, providing reference data for future clinical studies on HRA in children.

Summary: This study analyzed the improvement of blood pressure variability in obese youth with sleep-disordered breathing after positive airway pressure treatment, showing significant decreases in nighttime blood pressure. The findings suggest that positive airway pressure treatment can lead to a clinically significant improvement in sympathetic nerve activity in youth with obesity and sleep-disordered breathing.

Summary: The century-long debate on bodily states and emotions continues, with this study investigating the brain-heart interplay during emotional experiences. Using a computational model, the researchers found that sympathetic-vagal activity plays a leading and causal role in initiating the emotional response, and the subsequent dynamic interplay between the central and autonomic nervous systems sustains the processing of emotional arousal.

Summary: The study found that cardiac parasympathetic (PNS) and sympathetic (SNS) activity in childhood follow different developmental trajectories, with PNS activity showing a cubic trend and SNS activity showing a linear decrease. There are differences in SNS and PNS activity levels between boys and girls at different ages, with high interindividual variation observed at all ages.

Summary: The study showed that listening to Mozart K.448 music can reduce interictal epileptiform discharges in children with epilepsy and enhance parasympathetic activity. Despite the small sample size, the results did not reach statistical significance, but revealed the potential of music in the treatment of pediatric epilepsy.

Summary: This study demonstrates that narcissism and self-esteem have distinct physiological indicators. Children predisposed to narcissism show elevated physiological arousal in social-evaluative contexts, while children predisposed to high self-esteem show lowered physiological arousal.

Summary: Pre-meal heart rate variability is positively related to perceived loss-of-control eating during a laboratory meal designed to simulate an episode of loss-of-control eating. However, this association is only significant among participants with recent reported episodes of loss-of-control eating.

Summary: Nightmare disorder is characterized by dysfunctional emotion regulation and poor sleep quality, including abnormal arousal processes and sympathetic influences. This study aimed to investigate the cardiac variability of frequent nightmare recallers (NMs) compared to healthy controls (CTL) during sleep, pre-sleep wakefulness, and an emotion-evoking picture-rating task. The results showed autonomic dysregulation during sleep in NMs, with no significant differences in cardiac variability between the two groups. However, NMs exhibited increased heart rate (HR) and reduced HRV during the emotion-evoking picture-rating task, indicating disrupted emotion regulation under acute distress.

Summary: Beat-to-beat heart rate variability is associated with neural activity in both reflex regulating areas and higher brain regions. The temporal dynamics of brain activity in relation to heart activity can be captured by heartbeat evoked potentials (HEP). The study investigated whether HEP amplitudes across the cardiac cycle reflect brain activity contributing to heart rate regulation, demonstrating that HEPs allow capturing brain activity associated with postponing the subsequent heartbeat.

Summary: This study examined the effect of treatment on heart rate variability (HRV) in children with Down Syndrome (DS) and sleep disordered breathing (SDB). The results showed that improvement in SDB prevented a decline in HRV, suggesting that managing the severity of SDB can help maintain autonomic control in children with DS.

Summary: The study revealed impaired autonomic nervous function in children with OSA. Low-grade inflammation was found to be an independent risk factor for altered LF/HF ratio in the wake stage. AHI influenced sympathetic-vagal balance during falling asleep.

Summary: This study compared multiple indices of the autonomic nervous system between children and adults at rest and found that children exhibited higher autonomic tone compared to adults. This may reflect a physiological state in childhood that is compatible with developmental acquisitions.

Summary: This systematic review discusses the evidence that respiration plays a fundamental role in coordinating neural activity, behavior, and emotion. The main findings are that respiration affects neural activity in various brain regions, modulates different frequency ranges in brain dynamics, and different respiration protocols yield different neural and mental effects. The effects of respiration on the brain are related to concurrent modulation of biochemical and physiological variables. The connection between respiration and neuro-mental features like emotion holds promise for therapeutic usage in mental disorders.
