The tumor was located on the right side posterior to the posterior central sulcus (Fig. 1). The neurosurgeon left the resection incomplete due to lack of demarcation of tumor tissue and the close proximity of deeper tracts (Fig. 1).
Brain target for rTMS treatment. The target was at the right parieto-temporal junction, between P4 and T6 EEG electrode locations. The red arrow represents the E-field orientation of the induced active TMS pulses.
