Statistics of correlation analyses between the experience‐related differences in the M1 activity and connectivity during the untrained‐hand's performance
| The left M1, contralateral to the performing (untrained) hand | |||||
|---|---|---|---|---|---|
| ΔCC | ΔCC | ΔCC | ΔCC | ΔCC | |
| M1 – M1 | left‐M1 – left‐SMA | left‐M1 – right‐SMA | left‐M1 – left‐PMd | left‐M1 – right‐PMd | |
| ΔCV‐Act within the ‘untrained’ (left) M1 | r = 0.39 | r = −0.08 | r = 0.06 | r = 0.01 | r = −0.02 |
| P = 0.16 | P = 0.77 | P = 0.83 | P = 0.97 | P = 0.96 | |
| The right M1, ipsilateral to the performing (untrained) hand | |||||
|---|---|---|---|---|---|
| ΔCC | ΔCC | ΔCC | ΔCC | ΔCC | |
| M1 – M1 | right‐M1 – right‐SMA | right ‐M1 – left ‐SMA | right ‐M1 – right ‐PMd | right ‐M1 – left ‐PMd | |
| ΔCV‐Act within the ‘trained’ (left) M1 | r = 0.70 | r = 0.27 | r = 0.44 | r = 0.33 | r = 0.67 |
| P = 0.01 | P = 0.34 | P = 0.11 | P = 0.23 | P < 0.01 | |
| p cor = 0.06 | P cor < 0.05 | ||||
ΔCV‐Act, experience‐related differences in the magnitude of activity; ΔCC, experience‐related differences in the strength of functional connectivity; P cor, values corrected for multiple tests using Bonferroni adjustments.
