Whole-group RFX analysis for the [LEARNING], [EASY], [REPLAY] contrasts, [t₍₂₂₎ = 2.19; p_UNCORRECTED < 0.04], and the [LEARNING − (REPLAY + EASY)] contrast [t₍₂₂₎ = 2.10; p_UNCORRECTED < 0.04]. BA, Brodmann area; SMA, supplementary motor area; M1, primary motor cortex; PMd, dorsal premotor cortex; S1, primary somatosensory cortex; damH, damaged hemisphere; undamH, undamaged hemisphere; mm³, activated volume (equivalent to the number of activated anatomical voxels since voxels were isotropic (1 mm³), see the Material and Methods Section).

^**No correlation have been done between the PI and the beta weights in the ROIs activated during [EASY].
