Long-term endurance training significantly influences how the autonomic nervous system
controls heart function. Endurance training increases parasympathetic activity and …

This review first gives an overview on the concept of fractal geometry with definitions and
explanations of the most fundamental properties of fractal structures and processes like self …

Research in cognitive neuroscience has extensively demonstrated that the temporal
dynamics of brain activity are associated with cognitive functioning. The temporal dynamics …

Scale-free dynamics, with a power spectrum following P∝ f− β, are an intrinsic feature of
many complex processes in nature. In neural systems, scale-free activity is often neglected …

Neurophysiological field-potential signals consist of both arrhythmic and rhythmic patterns
indicative of the fractal and oscillatory dynamics arising from likely distinct mechanisms …

In contrast to scalp EEG, our knowledge of the normal physiological intracranial EEG activity
is scarce. This multicentre study provides an atlas of normal intracranial EEG of the human …

We illustrate a general principal of electrical potential measurements from the surface of the
cerebral cortex, by revisiting and reanalyzing experimental work from the visual, language …

Electrophysiological mass potentials show complex spectral changes upon neuronal
activation. However, it is unknown to what extent these complex band-limited changes are …

Noise can assist neurons in the detection of weak signals via a mechanism known as
stochastic resonance (SR). We demonstrate experimentally that SR-type effects can be …

Neurophysiological recordings are dominated by arhythmical activity whose spectra can be
characterised by power-law functions, and on this basis are often referred to as reflecting …
