The present review discusses a well-established method for characterizing resting-state
activity of the human brain using multichannel electroencephalography (EEG). This method …

A celebrated and controversial hypothesis suggests that some biological systems—parts,
aspects, or groups of them—may extract important functional benefits from operating at the …

Fractals are fascinating, not only for their aesthetic appeal but also for allowing the
investigation of physical properties in non-integer dimensions. In these unconventional …

In the recent years, short-term heart rate variability (HRV) describing complex variations of
beat-to-beat interval series that are mainly controlled by the autonomic nervous system …

INTRODUCTION A disease is rarely a straightforward consequence of an abnormality in a
single gene, but rather reflects the interplay of multiple molecular processes. The …

Alzheimer's disease (AD) is the most common neurodegenerative disease among the
elderly with a progressive decline in cognitive function significantly affecting quality of life …

Fractal structures are found in biomedical time series from a wide range of physiological
phenomena. The multifractal spectrum identifies the deviations in fractal structure within time …

The human organism comprises various physiological and organ systems, each with its own
structural organization and functional complexity, leading to complex, transient, fluctuating …

In this work we study the characteristics of heart rate variability (HRV) as a function of age
and gender. Our analysis covers a wider age range than that studied so far. It includes …
