Significant clusters where CCI (Orange/Red; upper panel) and Openness (Blue; lower panel) were inversely related to FA.

Arrows indicate maximal significant regions in coronal plane (left), axial plane (middle), and sagittal plane (right). Green regions indicate “skeleton” white matter tracts in which statistical relationships were explored between behavioral variables (CCI/Openness) and white matter integrity (FA). Figures are presented in radiological convention – left side = right hemisphere.
