Figure 7

Sex differences in coupling are driven by thicker gyral cortex in females. Mean cortical thickness data is plotted for gyral and sulcal cortex separately in clusters of significant sex differences in coupling. (A) Females show lower coupling in left frontal lobe. (B) Within this cluster gyral cortex is thicker for females than males, while sulcal cortex is similar between the two sexes. (C) Similarly, in right parieto-occipital junction females have stronger negative coupling due to (D) thicker gyral cortex than males in this region. Gyral and sulcal cortex are defined as above and below the median in each region. Color bars show signed p-values where blue represents more negative coupling in females than males.
