Abstract

Advances in structural and functional neuroimaging have allowed researchers to study the neural correlates of aphasia. In general, nonfluent aphasiasare associated with left pre-rolandic lesions, and fluent aphasias occur with left post-rolandic lesions that spare pre-rolandic areas. However, functional neuroimaging studies have shown that neural dysfunction often extends beyond the structural lesion. Recovery of aphasia is better when lesions spare frontal-subcortical white matter and temporal-parietal cortex. Functional neuroimaging studies of aphasia recovery have indicated some right hemisphere activation, bur better recovery and response to treatment is associated with increased left hemisphere activation in regions surrounding structural lesions.
