Introducing a new method for mapping the motor cortex in patients with tumors in precentral regions with navigated transcranial magnetic stimulation and intraoperative direct cortical stimulation

Noman Zafar, Alexander Opitz, Volker Bockermann & Veit Rohde
Objective: Navigated transcranial magnetic stimulation (TMS) is a widely used method to preoperatively assess hand knob location in patients with brain tumors related to the precentral gyrus. TMS induces an electric field in the brain that varies depending on coil position and orientation. The distance[for full text, please go to the a.m. URL]
