FIG. 5.

Positive and negative correlation networks (CNs). Correlations between the averaged FA values among voxels included in the tracts and speed of perceptual alternation are shown here. (a) and (b) demonstrate the spatial mapping on the transverse plane and on coronal plane, respectively. The blue lines show positive CNs (bundles of tracts showing positive correlation with the speed of perceptual alternations), and the red links show negative CNs (bundles of tracts showing negative correlation with speed of perceptual alternations). The size of yellow dots indicates the depth of the brain regions in the three-dimensional space. When the intensity of correlation value is 0.7, the corresponding p-value in Spearman's rank test is ∼0.01, and the expected value of false discovery rate (FDR) is <0.05 (Benjamini and Hochberg, 1995).
