Lévy walks describe patterns of intermittent motion with variable step sizes. In complex
biological systems, Lévy walks (non-Brownian, superdiffusive random walks) are associated …

A special class of random walks, so-called Lévy walks, has been observed in a variety of
organisms ranging from cells, insects, fishes, and birds to mammals, including humans …

The movement of many animals may follow Lévy patterns. The underlying generating
neuronal dynamics of such a behavior is unknown. In this paper we show that a novel …

In this research we have analyzed functional magnetic resonance imaging (fMRI) signals of
different networks in the brain under resting state condition. To such end, the dynamics of …

The movement patterns of a diverse range of animals have scale-free characteristics. These
characteristics provide necessary but not sufficient conditions for the presence of movement …

Lévy flights represent the best strategy to randomly search for a target in an unknown
environment, and have been widely observed in many animal species. Here, we inspect and …

ABSTRACT Lévy walks are a mathematical construction useful for describing random
patterns of movement with bizarre fractal properties that seem to have no place in biology …

Lévy walks (LWs) are spatiotemporally coupled random-walk processes describing
superdiffusive heat conduction in solids, propagation of light in disordered optical materials …

Propagation of discharges in cortical and thalamic systems, which is used as a probe for
examining network circuitry, is studied by constructing a one-dimensional model of integrate …

Brains are usually described as input/output systems: they transform sensory input into
motor output. However, the motor output of brains (behavior) is notoriously variable, even …
