While the majority of individuals with MS develop significant clinical disability, a subset experiences a disease course with minimal impairment even in the presence of significant apparent tissue damage on magnetic resonance imaging (MRI).

Recent evidence has implicated cortical reorganization as a mechanism to limit the clinical manifestation of …
