Dependence of changes in FC on uncorrelated sensory (pi) and motor (mi) indices of learning. Mean correlation between individual changes in FC and exclusively motor (mi), sensory (pi), or mutual (M) components. SEs are specified using red bars. The mean and SE for a specific link is calculated over significant voxels (Z > 2.7) defined on the union of clusters associated with MI and PI. Each color-coded link comprises a pair of regions in which the first region represents the location of the ROI and the second region represents the area in which the activated cluster is located. *p < 0.001, significant differences in the correlation between ΔFC with mi and pi (Wilcoxon's rank-sum test).
