Brain regions where rsFC changes from Rest 1 to Rest 2 are significantly correlated with the learning index, in young (A) and old (B) participants. MNI coordinates locate the correlation peak in each region of significance. Peak r scores show the correlation coefficients in the group for which a significant correlation has been identified (young or old) and the corresponding values in the other group (old or young). Positive (respectively, negative) values indicate that rsFC post‐training increases (respectively, decreases) are associated with better learning performance. The P‐values assess the differences between young and old individuals in the peak r scores. The family‐wise error was controlled for the number of spatial degrees of freedom involved in MNE reconstructions using a Bonferroni correction (* indicates P < 0.0009; # indicates P _{uncor r} < 0.01). SII, secondary somatosensory cortex; SMA, supplementary motor area; V1, primary visual cortex; V2, secondary visual cortex.
