Jimmy Zepa obtained his medical degree at the University of Magdeburg and went on to become a resident in

Neurosurgery at the Hospital Merheim in Cologne. In his residency, he started actively working with Prof. Hartmann on presurgical

language mapping using neuronavigation to optimise planning of neurosurgery and prevent postsurgical neurological deficits of

language. Since 2021 he has been working on his doctoral thesis entitled: “Language mapping in patients with parenchymatous

tumor in language eloquent areas.”


The gold standard of the lesion-based mapping of speech pathways is the Direct cortical stimulation (DCS) during awake

surgery. But there are many studies that proved that an alternative option due to many inconveniences of the DCS is the navigated

repetitive TMS. In my current study, I want to prove that TMS can be use as preoperative diagnostical method to target out the localization

of essential cortical language regions around the lesion that will undergo surgery, so that the level of postoperative Aphasia could be

reduced. I’ll illustrate it with two patients that I am testing.
