heart has made it one of the most valuable tools for researchers interested in health and …

There is a bidirectional relationship between affective disorders and cardiovascular
abnormalities, often described as a downward spiral, whereas major depressive disorders …

Metrics of heart period variability are widely used in the behavioral and biomedical sciences,

Objective This study evaluates the associations between people's trait-like patterns of stress
in daily life (stressor frequency, perceived stressor severity, affective reactivity to stressors …

Both heart rate (HR) and brain functioning involve the integrated output of a multitude of
regulatory mechanisms, that are not quantified adequately by linear approximations such as …

The neurovisceral integration model aims to account for the complex interplay between
physiological, cognitive, and emotion regulation processes through their support by common …
