The complex‐systems approach to cognitive science seeks to move beyond the formalism of
information exchange and to situate cognition within the broader formalism of energy flow …

Self-organized criticality purports to build multi-scaled structures out of local interactions.
Evidence of scaling in various domains of biology may be more generally understood to …

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 …

The intuitive notion that a healthy organism is characterised by regular, homeostatic function
has been challenged by observations that a loss of complexity is, in fact, indicative of ill …

Traditional theories of psychology define the cognitive system as composed of insular,
encapsulated components, controlled by a central executive. An alternative hypothesis …

Our goal is to explore the relationship between two traditionally unrelated concepts, fractal
structure and entropy production, evaluating both within the central nervous system (CNS) …

It has been suggested that human behavior in general and cognitive performance in
particular emerge from coordination between multiple temporal scales. In this article, we …

Fractal processes, like trees or coastlines, are defined by self‐similarity or power law scaling
controlled by a single exponent, simply related to the fractal dimension or Hurst exponent …

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

This article addresses the still popular but incorrect idea that monofractal (sometimes called
“fractal” for short) structure might be a definitive signature of nonlinearity and, as a corollary …
