Multivariate relationships between cognitive performance and SD_BOLD.

<p><b>A</b>: PLS spatial pattern. Blue regions indicate greater and yellow/red regions indicate lesser SD_BOLD with better performance on fluid and memory, and worse performance on vocabulary. Significant regions: bootstrap ratio > ±3. M1: primary motor, PMC: premotor cortex, MFG: middle frontal gyrus, SFG: superior frontal gyrus, SMA: supplementary motor area, PCC: posterior cingulate gyrus, PCUN: precuneus, ACC: anterior cingulate cortex, PCC: posterior parietal cortex, SMG: supramarginal gyrus, INS: insula, OCCIP: occipital cortex, STG: superior temporal gyrus, TP: temporal pole, MTG: middle temporal gyrus, MTL: medial temporal lobe, IFG: interior temporal gyrus, TF: temporal fusiform, CEREB: cerebellum, TH: thalamus, <b>B</b>: Correlation magnitudes (Pearson r) between 4 cognitive constructs and SD_BOLD during rest (permuted p < 0.001, error bars represent bootstrapped 95% confidence intervals). The speed construct did not contribute to the LV as its error bars cross the zero. <b>C</b>: Scatterplot showing the relationship between global FA (WM integrity) and cognition–SD_BOLD relationship.
