Objective: The treatment of brain arteriovenous malformations (BAVM) is still contrarily discussed. Despite the debatable results of the ARUBA trial, most BAVMs still require treatment depending on the Spetzler-Martin (SM) grading.

Objective: Besides motor and language function, tumor resections within the frontal and parietal lobe were also reported to cause neuropsychological impairment, like prosopagnosia. Since non-navigated TMS was already used to detect and impair neuropsychological cortical function, this study now aims[for full text, please go to the a.m. URL], 67.
