[Functional MRI-motor reorganization].

Abstract

With rapid advancement of non-invasive imaging technologies, it is now possible to perform a detailed assessment of brain functional reorganization in humans. Studies in hemiparesis patients due to corticospinal tract impairment strongly suggest an important role of ipsilateral cortex and supplemental motor cortices in functional reorganization of the motor system. Studies in patients with peripheral nerve disease indicate that central nervous system reorganization indeed occurs based on peripheral motor dysfunction. Data on cerebellar reorganization indicate a potential role of the reticular formation in motor functional reorganization.
