The present thesis is based on two publications for which we performed language mapping in patients suffering from left-sided perisylvian brain lesions by repetitive navigated transcranial magnetic stimulation (rTMS), functional magnetic resonance imaging (fMRI), and direct cortical stimulation (DCS) during awake surgery.
In summary, we ascertained that rTMS language mappings should be analyzed with specific thresholds in order to avoid false-positive results. Furthermore, we showed that by the combination of language mapping results obtained by rTMS and fMRI, the strengths of both techniques are available for preoperative language mapping assessment. Moreover we could prove that, in case of negative language mapping, rTMS is less affected by a brain lesion than fMRI.
