Summary
Repetitive transcranial magnetic stimulation (rTMS) may be able to provide a moderately detailed localization of language functions in the brain. We propose to test the ability of rTMS to locate the substrate of visual naming to a limited area of the temporal lobe in patients with temporal lobe epilepsy before and after surgical resections. The study is expected to yield information on the organization of language in the temporal lobes and how unilateral temporal lobe lesions and lobectomy cause relocation of language mechanisms in the lesioned and in the other hemisphere. It will also be a preliminary step in the development of a clinically useful procedure for locating critical language areas in potential surgical candidates.
