Frequency distributions of correlation coefficients.

<p>A shows the frequency distribution of correlation coefficients (X axis) of spatial correlation between each pair of ICs from the four datasets. B. Assessing the spatial correlations of each IC from the attention dataset with ICs from the other three datasets generated six correlation coefficients (Please see the table in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0117029#pone.0117029.g009" target="_blank">Fig. 9</a>). B shows the frequency distribution of the smallest among six correlation coefficients for each IC from the attention dataset.
