Physiological processes—such as, the brain's resting-state electrical activity or hemodynamic fluctuations—exhibit scale-free temporal structuring. However, impacts common in biological systems such as, noise, multiple signal generators, or filtering by transport function, result in multimodal scaling that cannot be reliably assessed by standard analytical tools that assume unimodal scaling. Here, we present two methods to identify breakpoints or crossovers in multimodal multifractal scaling… 
Impact of Healthy Aging on Multifractal Hemodynamic Fluctuations in the Human Prefrontal Cortex
Correlation-based signal improvement (CBSI) enhanced the signal in terms of interpreting changes due to neural activity or local/systemic hemodynamic influences and suggested an attenuation of neurovascular coupling reflected by a decreased autocorrelation of the neuronal component concomitant with an accompanying increased autoc orrelation ofThe non-neuronal component in the elderly group.
Multiple-Resampling Cross-Spectral Analysis: An Unbiased Tool for Estimating Fractal Connectivity With an Application to Neurophysiological Signals
MRCSA is introduced as an extension of IRASA from the univariate to the bivariate case and shows that the cross-spectral exponent as well as the proportion of fractal coupling increases almost uniformly over the cortex during the rest-task transition, likely reflecting neural desynchronization.
Scale-Free Coupled Dynamics in Brain Networks Captured by Bivariate Focus-Based Multifractal Analysis
While most connectivity studies investigate functional connectivity (FC) in a scale-dependent manner, coupled neural processes may also exhibit broadband dynamics, manifesting as power-law scaling of
Multifractal dynamics of resting-state functional connectivity in the prefrontal cortex.
The authors found the DFC in the prefrontal cortex fluctuating according to scale-free, specifically multifractal dynamics, and this may well be another indication of a self-organized critical state underlying resting-state brain activity.
Fractal and Multifractal Properties of Electrographic Recordings of Human Brain Activity: Toward Its Use as a Signal Feature for Machine Learning in Clinical Applications
Some of the practical challenges of applying fractal geometry to brain dynamics—and as a putative feature for machine learning applications, are highlighted and solutions to enable its wider use in neuroscience are proposed.
Multifractal and Entropy-Based Analysis of Delta Band Neural Activity Reveals Altered Functional Connectivity Dynamics in Schizophrenia
The results imply that dynamic features of DFC such as its multifractal properties and entropy are potent markers of altered neural dynamics in SZ and carry significant potential not only in better understanding its pathophysiology but also in improving its diagnosis.
Fractal Analysis of BOLD Time Series in a Network Associated With Waiting Impulsivity
Fractality as determined via H is a promising marker to quantify deviations in network functions at an early stage and, thus, to be able to inform preventive interventions before the manifestation of a disorder.
Multifractal Dynamic Functional Connectivity in the Resting-State Brain
The proposed analytical tools allow for capturing the fine details of functional connectivity dynamics that are evidently present in DFC, with the presented results implying that multifractality is indeed an inherent property of both global and local DFC.
Monofractal analysis of functional magnetic resonance imaging: An introductory review
This review presents a brief overview of the theory of fMRI monofractal analysis followed by notable findings in the field and identifies the future directions necessary for its progression towards impactful functional neuroscience discoveries and widespread clinical use.
Multifractal Functional Connectivity Analysis of Electroencephalogram Reveals Reorganization of Brain Networks in a Visual Pattern Recognition Paradigm
Results show that reorganization of scale-free coupled dynamics takes place during visual pattern recognition independent of difficulty level, and indicate that investigating multifractal FC under various conditions – such as mental workload in healthy and potentially in diseased populations – is a promising direction for future research.

Quantification of scaling exponents and crossover phenomena in nonstationary heartbeat time series.
A new method--detrended fluctuation analysis (DFA)--for quantifying this correlation property in non-stationary physiological time series is described and application of this technique shows evidence for a crossover phenomenon associated with a change in short and long-range scaling exponents.

A novel perspective on memory function is provided by demonstrating that the multifractal nature of spike trains reflects hippocampal microcircuit activity that can be used to detect and quantify cognitive, physiological, and pathological states.

It is demonstrated that the method, based on the wavelet-transform modulus-maxima representation, works in most situations and is likely to be the ground of a unified multifractal description of self-affine distributions.
Adaptive Fractal Analysis Reveals Limits to Fractal Scaling in Center of Pressure Trajectories
Results suggest the fGn–fBm framework is not appropriate for modeling COP signals, and ON–OFF intermittency might provide a better modeling framework for the COP, and multiscale approaches may be more appropriate for analyzing COP data.
Physiological time series: distinguishing fractal noises from motions
A new method using signal summation conversion (SSC) greatly improves the classification and the reliability of Ĥ, the estimates of H, for the times series, and suggests that the flow signal is the summation of a set of local velocities from neighboring vessels that are negatively correlated, as if induced by local resistance fluctuations.
