Figure 5

Voxel-wise t-test showing amplitude change for all groups (p = 0.05). All the analysis was done using acute stage of each group as baseline. A-D were from single median nerve injury groups. Significant intra-hemispheric cortical plasticity was demonstrated when right ulnar nerve was stimulated (D. circled in red). E-H were acquired from combined nerve injury group. Both inter-and intra-hemispheric plasticity were found during nerve stimulations, with the healthy nerve bundle on the healthy side being dominant (E, H circled in red).
