Abstract
Functional magnetic resonance imaging (fMRI) allows noninvasive localization of cerebral activation with relatively high spatial and temporal resolution. The considerable potential for the elucidation of the mechanisms of brain function has made it a useful tool to investigate the neural substrate of motor, sensory and cognitive functions. Understanding derived from these basic cognitive neuroscience investigations is beginning to be applied to clinically relevant problems. In this article, applications to multiple sclerosis (MS) are reviewed, which address the challenging notion that adaptive cerebral plasticity may have an important influence on the relationship between MS pathology and its clinical expression.
