Projects on Language Recovery Using fMRI

Neuroimaging of Language Recovery

We are now interested in examining whether behavioral language recovery observed in treated patients is correlated with underlying functional changes in the brain as a result of treatment. Hence, we have started functional neuroimaging (fMRI) experiments to investigate activation in brain regions in patients with aphasia before and after they receive treatment.

It is hoped that changes in activation that are observed in the brain scans will provide us with some understanding of how language is recovered in the damaged brain following treatment. This important data will contribute to the growing body of evidence supporting the notion of brain plasticity in adulthood and after brain damage.

Our work is part of a larger effort to examine the nature of language recovery after rehabilitation. Read about this work here.
