摘要: Background and Purpose Stroke recovery mechanisms remain incompletely understood, particularly for subjects with cortical stroke, in whom limited data are available. We used functional magnetic resonance imaging to compare brain activations normal controls who recovered from hemiparetic stroke. Methods Functional was performed ten stroke good recovery, five deep, infarcts. Brain activation achieved by index finger-tapping. Statistical parametric maps were obtained using a t test threshold of P<.001. In bilateral motor regions, the volume activated each subject compared distribution volumes among nine controls. Results Control several regions. During hand finger-tapping, same regions as controls, often larger volume. unaffected hemisphere, sensorimotor cortex activat...
