英文摘要
We performed both fMRI and diffusion tensor tractography in stroke patients in an attempt to elucidate the mechanism of motor recovery after stroke. The observed change in the brain motor network after stroke was a dynamic process including (1) functional recovery from reversible damage and (2) compensation, recruitment, and reorganization of brain motor network, depending on the damage to the pyramidal tract. This change was observed within the first 2 months after stroke, suggesting the existence of a critical period.
