Resting state fMRI data will be analyzed following a previously published protocol for functional connectivity in language networks. Time series of BOLD-signal fluctuations within the right inferior frontal gyrus (pars triangularis, seed region) will be correlated with signal fluctuations in the non-infarcted gray matter of the left hemisphere on voxel by voxel basis using the MATLAB toolbox for functional connectivity implemented in SPM. We expect interhemispheric connectivity of the right inferior frontal gyrus with left hemisphere language cortex to be higher in those patients who will show the greatest response to therapy.
