Figure 5. Network plasticity after stroke.
Perilesional areas can show enhanced beta-band coherence with the rest of the brain during the first weeks after stroke. An example is shown in yellow-red in (a), the lesion is marked in dark grey. Enhancement of coherence between ipsilesional M1 and the rest of the brain was associated with better motor improvement in the subsequent months (b). Coherence between Broca’s area and the rest of the brain was associated with language improvement (c). Modified after (Nicolo et al., 2015b) with permission.
