Figure 6.
Effects of finger-specific training or immobilization on mediolateral representations of short-latency intracortical inhibition (SICI) in M1HAND probed with sulcus shape-based, dual-pulse TMS. The AUC(SICI) at day 7 were expressed as percentage of AUC(SICI) at baseline to capture relative changes in overall SICI after immobilization and training. Left panels. Individual AUC(SICI) ratios for the FDI and ADM muscle representations for the three types of interventions. An AUC ratio above the 100% line reflects a postinterventional decrease in SICI (i.e., disinhibition) relative to baseline. The color of the lines indicates whether the muscle was trained (green), immobilized (red), or neither immobilized nor trained (gray); Right panels. Distances between the average mediolateral position of the SICI profiles (DWMP) are displayed before and after the intervention for the three main types of interventions. Triangles symbolize the index finger and circles symbolize the little finger.
