Figure 2

Figures 2 and 3 show 2 possible ways in which PMC could contribute to functional recovery. The relative engagement of ipsilesional versus contralesional PMC in recovery is likely influenced by the extent and location of the stroke. However, it is important to understand that performance improvements and recovery may emerge from activity in more widespread networks than the ones depicted in Figures 2 and 3. Figure 2 depicts how ipsilesional PMC may reorganize following a small lesion in M1 or corticospinal pathway. Abbreviations: PMC, premotor cortex; DLPFC, dorsolateral prefrontal cortex; SMA, supplementary motor cortex; M1, primary motor cortex.
