Evidence of motor learning driven neuroplasticity in white matter regions-of-interest. Panel A: summary of ROI results across: (1) DTI—blue; significant increase in DTI FA (baseline < endpoint; p < 0.05, FWE); (2) WM-HRF—orange; significant decrease in HRF dispersion derivative (baseline > endpoint; p < 0.05, FWE); and (3) FCT—green; significant increase in FCT FA (baseline < endpoint; p < 0.05, FWE). Panel B: convergence of LFO results, with graphs showing common significant amplitude decreases across frequency bands (baseline > endpoint; p < 0.05) with interquartile ranges
