Figure 6: Fit parameters based on Eq. (16) for various ROIs:

Figure 6:

a) Fit parameters of kurtosis time-dependence averaged over 10 subjects in ROIs of deep and cortical gray matter (Dale et al., 1999; Destrieux et al., 2010). A three degrees of freedom least squares fit based on Eq. (16) leads to a dynamical exponent ϑ ≈ 0.5(red line) consistent among different ROIs. The 3 ROIs showing insignificant time-dependence in kurtosis are marked by a cross. b) Fit parameters in a) are visualized in GM ROIs of a brain.
