在脑卒中患者的神经影像学研究中，共激活可能是移动患肢时双侧运动区募集增加的原因。在这里，我们研究了8例脑卒中后功能磁共振成像和同步肌电图。根据EMG，5例患者的双侧运动前区和初级运动皮质明显招募，表现为严格的单侧表现。由于患者的运动恢复良好，这种增加的募集表明对梗死的适应性反应。
In neuroimaging studies of stroke patients, coactivation may account for increased recruitment of bilateral motor areas when moving the affected limb. Here we studied eight patients after stroke with fMRI and simultaneous EMG. Bilateral recruitment of premotor and primary motor cortices was evident in five patients with strictly unilateral performance per EMG. Because patients had excellent motor recovery, this increased recruitment suggests an adaptive response to the infarct.
