The past 40 years have witnessed extensive research on fractal structure and scale-free
dynamics in the brain. Although considerable progress has been made, a comprehensive …

Many neurophysiological variables such as heart rate, motor activity, and neural activity are
known to exhibit intrinsic fractal fluctuations–similar temporal fluctuation patterns at different …

This essay is presented with two principal objectives in mind: first, to document the
prevalence of fractals at all levels of the nervous system, giving credence to the notion of …

Excitable cells and cell membranes are often modeled by the simple yet elegant parallel
resistor-capacitor circuit. However, studies have shown that the passive properties of …

Transfer of competency in a perceptual task often depends on shared information between
anatomically different perceptual subsystems. The problem of studying transfer involves …

Time series of human performances present fluctuations around a mean value. These
fluctuations are typically considered as insignificant, and attributable to random noise. Over …

A large number of studies have demonstrated the existence of metabolic covalent
modifications in different molecular structures, which are able to store biochemical …

The Hurst effect in the signals describing ion channels' activity has been known for many
years. This effect is present in the experimental recordings of single-channel currents, but …

Ion channels are transport proteins present in the lipid bilayers of biological membranes.
They are involved in many physiological processes, such as the generation of nerve …

Ion channels mediate the transport of ions through the cell membrane and are involved in
key processes such as muscle contraction, nerve excitability and hormone secretion. For …
