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: This study aimed to synthesize and analyze the effects of different triggers of the diving response on cardiac vagal activity using a meta-analytic approach. A total of 17 studies with 311 participants were included in the review. The results showed a significant positive effect on RMSSD during exposure to triggers, but not post-exposure. Total body immersion had a larger effect compared to forehead cooling. Further research is needed to explore the role of cardiac sympathetic activity and other moderators.

Summary: This study found that repeated moderate heat exposure (RMHE) decreases resting sympathetic activity and heart rate, which can be considered beneficial effects. However, RMHE did not alter the sympathetic responses to stress.

Summary: This study analyzed the relationship between cardiac autonomic modulation and different intensities of physical activity in men and women. The results showed that moderate and vigorous physical activity were associated with better cardiac autonomic modulation in men, while light physical activity was associated with lower sympathetic modulation in women.

Summary: This study investigated the alterations in cardiovascular and autonomic nervous system functioning in individuals with long-term manifestations of COVID-19. The results revealed reduced heart rate variability, increased sympathetic modulation, and decreased parasympathetic modulation in long COVID patients. These findings suggest an increased risk for cardiovascular complications in long COVID patients.

Summary: In this study, the effects of different intensity exercise in a hot environment on cardiac autonomic modulation in individuals with controlled hypertension were investigated. The results showed that short bouts of exercise-heat stress did not significantly disrupt heart rate variability in physically active individuals with hypertension.

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: This study investigated the effects of oral THC on autonomic nervous system function in healthy adult women, finding that THC dose-dependently increased heart rate, decreased parasympathetic activity, and increased feelings of cannabis-like intoxication and anxiety. These results provide valuable insight into the relationship between autonomic effects of THC and subjective drug experience.

Summary: The decline in heart rate variability (HRV) and cortical thickness (CT) with increasing age was observed, with CT, particularly in the orbitofrontal cortex, explaining additional variance in HRV beyond the effects of aging. These effects were independent of sex and specific to HRV, with no significant association between CT and heart rate. The findings suggest that greater CT across adulthood may be crucial for maintaining healthy cardiac regulation, and greater cardiac vagal activity as reflected in HRV may slow brain atrophy.

Summary: Emotions play a crucial role in decision making and can influence consumer preferences. This study examined the impact of brands on product preference through physiological measurements and experiments. The findings suggest that brands can affect the arousal levels and choices of individuals.

Summary: The parasympathetic nervous system plays a crucial role in regulating whole-body glucose metabolism, but slow deep breathing did not have a significant impact on peripheral glucose metabolism after an oral glucose tolerance test. The study results suggest a link between the autonomic nervous system and insulin secretion, providing new insights for potential treatment approaches for impaired insulin secretion in diabetes.

Summary: This study tested the biological significance of Energy Proxy Traits (EPTs) in the embryonic development of Radix balthica at different temperatures, finding that EPTs are thermally sensitive and enable effective high-dimensional treatment clustering throughout organismal development. Results suggest that EPTs can capture aspects predictive of biological outcomes, potentially reflecting levels of energy turnover within the phenotype.

Summary: Thermal stress plays a potentially important role in selective adaptation within intertidal marine habitats. The two ecotypes of Littorina saxatilis in northwest Spain exhibit differences in thermal tolerance across shore height, with the upper-shore ecotype showing greater endurance of thermal stress compared to the lower-shore ecotype. This difference in thermal tolerance may contribute to maintaining population divergence and genetic segregation between the two ecotypes.

Summary: Phenomics provides a solution for quantifying developmental responses to elevated temperatures. Using energy proxy traits (EPTs), we assessed the thermal sensitivities of three species of freshwater snail. The results showed marked differences in thermal sensitivities between species, reflecting differences in embryonic physiology and behavior, as well as temperature-induced changes in physiological event timing.
