Fig. 3: Correlations of GWFC and ReHo with long-range FC.
From: Functional contrast across the gray-white matter boundary
a–c Illustration of GWFC, long-range functional connectivity, and ReHo. The blue points are on the mid-thickness cortical surface. The green points are in white matter. Some elements in this figure were created with Figdraw. d–f Spatial distributions of GWFC, long-range FC, and ReHo. The color represents the metric value (blue = low, red = high). g The scatter plot demonstrates a significant positive correlation (r(358) = 0.67, p = 7.5282e-49, 95% CI = [0.61, 0.73]) between GWFC and long-range FC. h Relationship between ReHo and long-range FC, showing a positive but weaker correlation (r(358) = 0.42, p = 3.7826e-17, 95% CI = [0.34, 0.51]). Each point in the scatterplot represents a brain region, and the fitted line depicts the general relationship between the two measured metrics. Two-sided Pearson correlation was used to assess the association between variables. GWFC gray-white matter functional connectivity, ReHo regional homogeneity; long-range FC long-range functional connectivity.
