Histograms portraying the FA12–FA90 difference between task-related beta coefficients in 5 ROIs; results are given separately for the individual subjects S1–S8 (the applied TR indicated below each subject label) and for the data pooled across all subjects (“All”; top row).

Voxels with significant activations [p < 0.05, false discovery rate (FDR)-corrected] at either or both of the FAs were extracted from each ROI, shown in 21 non-overlapping bins centered at −0.0050, −0.0045, … 0.0050. A voxel with equal beta coefficients for the two FAs would land in the centermost bin (indicated by a white vertical line). Values are provided for the number of voxels used in the analysis (N), the median of the difference of the beta values (, also illustrated by the blue-pink border), the scale of the y-axis (y) and the p-value for equal medians for the two FAs obtained by the Wilcoxon rank sum test; significantly different medians (p < 0.05) are emphasized.
