Figure 3. Structural-functional correlation between corpus callosum thickness and interhemispheric functional connectivity in alpha band.
Callosal thickness (100 sections) and inter-hemispheric coherence in alpha band of rolandic areas during an isometric handgrip performed with the right hand by patients and healthy controls and during the recovery period. The color bars encode Pearson's correlation coefficients r at uncorrected significance (p ≤ 0.05) while the smaller maps represent in dark blue the callosal portions surviving FDR-corrections for multiple comparisons (q ≤ 0.05). No significant correlations were found for the left (non dominant) hand in both groups (not shown).
