Figure 5.

(A) Scatterplot showing that participants with greater gray matter volume in the right inferior frontal gyrus (rIFG) had better sustained attention performance on the rapid visual information processing test of sustained attention (RVP) task (correlation coefficient, r = .267; linear correlation constant, R² = .071, p = .039). (B) Scatterplot showing that participants with greater white matter volume in the posterior portion of the right inferior fronto-occipital fasciculus (r-iFoF) had worse response inhibition performances (longer stop signal reaction time [SSRT]) on the stop signal task (the correlation coefficient, r = .294; the linear correlation constant, R² = .086, p = .023).
