Understanding the autonomic nervous system and homeostatic changes associated with
emotions remains a major challenge for neuroscientists and a fundamental prerequisite to …

The heart-rate dynamics are one of the most analyzed physiological interactions. Many
mathematical methods were proposed to evaluate heart-rate variability. These methods …

The neural regulation of circulatory function is mainly effected through the interplay of the
sympathetic and vagal outflows. This interaction can be explored by assessing …

An integrated approach to the complexity analysis of short heart period variability series (/spl
sim/300 cardiac beats) is proposed and applied to healthy subjects during the sympathetic …

Research into cardiovascular variabilities intersects both human physiology and quantitative
modelling. This is because respiratory and Mayer wave (or 10 s) cardiovascular oscillations …

Recently, methods have been developed to analyse couplings in dynamic systems. In the
field of medical analysis of complex cardiovascular and cardiorespiratory systems, there is …

While the standard network description of complex systems is based on quantifying the link
between pairs of system units, higher-order interactions (HOIs) involving three or more units …

Gait accelerometry is a promising tool to assess human walking and reveal deteriorating gait
characteristics in patients and can be a rich source of clinically relevant information about …

Complexity (or its opposite, regularity) of heart period variability has been related to age and
disease but never linked to a progressive shift of the sympathovagal balance. We compare …

The autonomic regulation is non-invasively estimated from heart rate variability (HRV). Many
methods utilized to assess autonomic regulation require stationarity of HRV recordings …
