Listed are all findings that are significant at p < 0.05 in the corresponding contrast with cluster-wise FWE correction for multiple comparisons. *Denotes a non-significant trend only (p = 0.082). Please note that we found a positive correlation only in MG between left SM1 and performance improvements of the LH, for details see “Results” Section and Figure 4.
