The complexity of spontaneous cerebral blood volume (CBV) fluctuations can emerge from random, fractal, or chaotic processes. Our aims were to define the contribution of these patterns to the observed complexity and to evaluate the effect of age and gender on it. The total hemoglobin content as the measure of CBV was monitored by near-infrared spectroscopy on volunteers (men n = 19, age = 20 to 78 years; women n = 23, age = 21 to 79 years). Random and fractal patterns were distinguished by the… 
Fractal characterization of complexity in dynamic signals: application to cerebral hemodynamics.
We introduce the concept of spatial and temporal complexity with emphasis on how its fractal characterization for 1D, 2D or 3D hemodynamic brain signals can be carried out. Using high-resolution
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.

Fractal and chaotic patterns coexisted in tissue perfusion and CBF fluctuations can be regarded as a robust phenomenon that is not abolished even by sustained hypotension at 40 mm Hg.
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.
Variability and Fractal Analysis of Middle Cerebral Artery Blood Flow Velocity and Arterial Blood Pressure in Subarachnoid Hemorrhage
FV and ABP fluctuated markedly despite homeostatic control and might indicate a loss of complexity and was associated with a less favorable outcome, therefore, the decomplexification theory of illness may apply to SAH.
The effect of ventricular assist devices on cerebral blood flow and blood pressure fractality.
The preservation of fractality in cerebral blood flow of VAD patients suggests that normal cardiac pulsation and central perfusion pressure changes are not the integral sources of cerebralBlood flow fractality and that intrinsic vascular properties such as cerebral autoregulation may be involved.

A small body of work suggests that parameters describing cerebral autoregulation can also display complexity, presenting significant variability that might also be non-stationary.

Wavelet-Based Fractal Analysis of rs-fMRI for Classification of Alzheimer’s Disease
The nonfractal-based approach provides a good representation of the brain’s neuronal activity and outperformed the fractal and Pearson-based connectivity approaches by 16.4% and 17.2%, respectively.


Fractal characterization of complexity in temporal physiological signals.
The authors demonstrate the importance of incorporating a step of signal classification according to the fGn/fBm model prior to fractal analysis by showing that missing out on signal class can result in completely meaningless fractal estimates.
Mechanisms underlying chaotic vasomotion in isolated resistance arteries: roles of calcium and EDRF.
It is concluded that the nonlinear interaction between a fast membrane oscillator and a slow intracellular oscillator generates chaos in vascular smooth muscle and that exogenous constrictor agonists and EDRF may be regarded as permissive and modulatory influences, respectively.
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.
Fractal analysis of spontaneous fluctuations in human cerebral hemoglobin content and its oxygenation level recorded by NIRS.
This study has applied the fractal model as implemented in a combination of the power spectral density (PSD) and the scaled windowed variance (SWV) methods in the analysis of human cerebrocortical hemoglobin signals in an attempt to assess their temporal pattern.
Measuring the Strangeness of Strange Attractors
Spontaneous Low-Frequency Oscillations Decline in the Aging Brain
Spontaneous low-frequency oscillations of oxyhemoglobin and deoxyhemoglobin declined strongly with aging during both rest and visual stimulation, which might indicate a declining spontaneous activity in microvascular smooth muscle cells, in conjunction with an increased vessel stiffness with aging.
Chaos and physiology: deterministic chaos in excitable cell assemblies.
This review examined the emerging science of deterministic chaos (nonlinear systems theory) and its application to selected physiological systems and to the neurosciences, demonstrating that the dynamics of neural mass activity reflect psychopathological states.
Oscillations in cerebral haemodynamics. Implications for functional activation studies.
The blood oxygenation level dependent (BOLD) contrast signal in functional magnetic resonance imaging (fMRI) provides highly spatially resolved deoxygenation maps of the activated cortex and several studies have been designed to elucidate its origin.
