Relationship of age and DMN WM microstructure with task-induced deactivation. The scatter plots show DMN deactivation magnitude in the single and mixed conditions (greater positive values = greater deactivation) plotted against age (A,B) and FA in the DMN-WM mask (C,D). Neither age (A) nor FA in the DMN-WM mask (C) correlated with task-induced deactivation in the single condition. Age (B) was negatively correlated and FA in the DMN-WM mask (D) was positively correlated with deactivation magnitude in the mixed condition. Dashed lines represent the linear best fit of the data. R² values indicate the portion of the total variance explained by the line.
