Scale-free and multifractal properties of fMRI signals during rest and task

Scale-free (or 1/f spectral) properties in functional MRI (fMRI) signals have been evidenced for a decade as intrinsic characteristics of ongoing brain activity [46]. Recently, they were shown to fluctuate across brain networks and to be modulated between rest and task [26]: Notably, Hurst exponent...
