P 14 Motor component of speech errors in rTMS language mapping

Using neuronavigated repetitive transcranial magnetic stimulation (rTMS) to disrupt language function during an online-task (e.g., picture naming) is a novel mapping technique which has recently been introduced for presurgical diagnostics in brain tumor patients. However, the method has some limitations due to its rather low specificity. Beyond its dependency on the task, the distinct error categories may have a major effect on the mapping results. We, here, studied the reliability and the spatial localization of rTMS-induced naming errors related to motor-speech function in contrast to semantic language errors.
