P 13 Congruency between speech-related areas investigated by fMRI and three rTMS protocols with different frequencies

Recently, language mapping by repetitive transcranial magnetic stimulation (rTMS) has gained a lot of interest in preoperative planning to preserve language function. However, the improvement of rTMS protocols is still a matter of debate since rTMS-evoked speech-errors appear relatively widespread over the brain and are rather poorly reliable, depending on the type of the speech-errors. We, therefore, investigated how rTMS-evoked speech-errors of distinct categories are located relatively to speech-related functional MRI (fMRI) clusters (serving as a widely used method for language mapping).
