Heart Rate Variability and Autonomic Control

Identification of peripheral neural circuits that regulate heart rate using optogenetic and viral vector strategies

The paper identifies peripheral neural circuits regulating heart rate in mice using optogenetic and viral vector strategies, revealing distinct roles of cholinergic and noradrenergic neurons.

Adrenergic activation of cardiac preganglionic neurons in nucleus ambiguous relies on persistent sodium current

This study shows adrenergic agonists enhance intrinsic excitability of cardiac preganglionic neurons in the nucleus ambiguus via persistent sodium current.

Involvement of gestational weight and body composition on autonomic recovery following aerobic exercise in children: a prospective, observational and analytical study

This study examines how birth weight and body composition affect autonomic recovery of heart rate variability in children after aerobic exercise.

Active information sampling varies across the cardiac cycle

The paper shows that humans self-initiate visual stimuli during cardiac systole, suggesting active information sampling integrates heart-related signals without affecting memory performance.

Focus of attention modulates the heartbeat evoked potential

This study shows that attentional focus modulates the heartbeat evoked potential (HEP), with higher HEP amplitudes during interoceptive attention compared to exteroceptive attention.

The age-dependent relationship between resting heart rate variability and functional brain connectivity

The paper examines how resting heart rate variability (HRV) relates to brain structure and function across different age groups, finding age-dependent changes in functional connectivity.

Parasympathetic and sympathetic activity are associated with individual differences in neural indices of selective attention in adults

This study examines the relationship between autonomic nervous system activity and neural indices of selective attention in adults, finding associations between heart rate variability and pre-ejection period with ERP components.

Task-induced deactivation in diverse brain systems correlates with interindividual differences in distinct autonomic indices

The paper examines how individual differences in autonomic nervous system activity during cognitive tasks correlate with task-induced deactivation patterns in specific brain regions.

Emotion lies in the eye of the listener: emotional arousal to novel sounds is reflected in the sympathetic contribution to the pupil dilation response and the P3

The paper examines how emotional arousal to novel sounds affects pupil dilation and ERP components, showing that sympathetic activation is linked to emotional responses.

Neural Responses to Heartbeats of Physically Trained and Sedentary Young Adults

This study compares neural responses to heartbeats between physically trained and sedentary young adults, finding differences in pre-stimulus processing that correlate with behavioral performance in the trained group.
