Three right-handed patients, suffering from left-sided opercular glioblastomas in two cases (47 years old male and 51 year old female) and from a left-sided astrocytoma WHO grade III of the angular gyrus (29 year old female) (Figure 1), initially presented with focal seizures. Moreover, each patient underwent MR imaging the day after surgery (Figure 1).

This system parcellates the cortex into 37 regions with special regard to anatomical brain structures (Figure 2, Table 2).
Data transfer. The screenshot shows the data transfer to the neuronavigation system of intraoperative DCS-positive points of patient 2 (BrainLAB Curve, BrainLAB AG, Feldkirchen, Germany).
