FA or MD and change in visuospatial working memory.

<p>Scatterplots showing linear relationships between change in FA or MD and change in visuospatial working memory. The plots show FA and MD in TOIs, plotted as z-transformed change values. For Spatial Span Backward scores age, sex and interval are regressed out, and for each TOI age, sex, interval and motion at both time points are regressed out. The partial correlation (r) between change in FA and MD in specific white matter tracts and change in Spatial Span Backward scores, controlling for age, sex, interval and motion at both time points are presented in each plot. The color-coded scatterplots represent the color of each specific white matter tract. Color codes refer to: Yellow: Inferior fronto-occipital fasciculus (IFOF), Red: Forceps major (FMaj), Light blue: Inferior longitudinal fasciculus (ILF) and Green: Uncinate fasciculus (UF). R = right.
