FIG. 5.

Per parameter correlation matrices for the time series associated with each component from spatial ICA (spatial ICs shown in Figs. 2 and 3) for the BNU (top two rows) and the HU data sets (bottom two rows), with each matrix labeled by the corresponding FCP component number. For each matrix, the parameters are in the following order (descending the y-axis and rightward along the x-axis): ALFF, fALFF, Hurst, standard deviation, and mean. The correlation coefficients are generally high among the first three components, as well as with the standard deviation in several cases; the series of means is often uncorrelated with the other parameters. fALFF, fractional ALFF.
