The brain is probably the most interesting example of a complex network having 1/f
variability as determined through the analysis of EEG time series and …

Human systems as well as other kinds of biological and complex systems have all been
reported to exhibit the power law behavior known as 1/f noise. The coherence of 1/f noise …

Researchers in psychology are paying increasing attention to temporal correlations in
performance on cognitive tasks. Recently, Thornton and Gilden (2005) introduced a spectral …

Abstract 1/f noise is a widespread phenomenon in physical and behavioral systems. It
typically occurs in systems that show long-term memory, and its sources are likely to be …

We study the electroencephalogram (EEG) of 30 closed-eye awake subjects with a
technique of analysis recently proposed to detect punctual events signaling rapid transitions …

Human neural and behavioral activities have been reported to exhibit fractal dynamics
known as 1/f noise, which is more aptly named 1/f scaling. Some argue that 1/f scaling is a …

Human cognition is fundamentally noisy. While routinely regarded as a nuisance in
experimental investigation, the few studies investigating properties of cognitive noise have …

1/f noise has been discovered in a number of time series collected in psychological and
behavioral experiments. This ubiquitous phenomenon has been ignored for a long time and …

\(1/f\) fluctuations are widely found in nature. During 80 years since the first observation by
Johnson (1925), long-memory processes with long-term correlations and\(1/f^{\alpha}\)(with …

We present a method for estimating the dynamical noise level of a 'short'time series even if
the dynamical system is unknown. The proposed method estimates the level of dynamical …
