Role of the Contralateral Inferior Frontal Gyrus in Recovery of Language Function in Poststroke Aphasia

Abstract

In some poststroke aphasics, right IFG activation is essential for residual language function. However, its compensatory potential seems to be less effective than in patients who recover left IFG function. These results suggest a hierarchy in recovery from poststroke aphasia and a (limited) compensatory potential of the nondominant hemisphere.
