Respiratory sinus arrhythmia (RSA) is being used increasingly in psychophysiological
studies as an index of vagal control of the heart and may be among the most selective …

Contemporary findings reveal that autonomic control of dually innervated visceral organs
does not lie along a single continuum extending from parasympathetic to sympathetic …

The cardiovascular system is essential for life and has been a central focus of psychophysiological
investigation for several reasons. First, at least some its parameters, like heart rate …

… The maior contributor to the resting potential is the Na+-K* pump which requires metabolic
energy and pumps 3 Na+ ions out of the cell while simultaneously bringing 2 K+ ions into the …

Behavioral contexts can evoke a variety of autonomic modes of response, characterized by
reciprocal, coactive, or independent changes in the autonomic divisions. In the present study, …

In this paper, we integrate recent theoretical and empirical developments in predictive
coding and active inference accounts of interoception (including the Embodied Predictive …

Heart period, systolic time intervals, low and high frequency heart period variability, blood
pressure, and respiration were measured in female subjects under three drug conditions (…

Large-scale intrinsic brain systems have been identified for exteroceptive senses (such as
sight, hearing and touch). We introduce an analogous system for representing sensations …
