Scatterplots for correlations between Post-Pre differences in FA, MD, and FC with individual performance gain (LU and N-back change).
BRAIN
Brain images were created with MRIcroGL (Bivariate scatterplots also revealed that microstructural plasticity in the stimulation target was associated with functional connectivity modulation: Higher decreases in gray matter MD were associated with increases in FC due to the intervention (As a control, we explored bivariate monotonic relationships between baseline integrity values (FA in white matter, MD in gray matter, and FC between the target and the resultant cluster) and behavioral performance gain. No substantial associations emerged (Supplementary Fig.
