Low threshold monopolar motor mapping for resection of primary motor cortex tumors

K. Seidel, J. Beck, L. Stieglitz, P. Schucht & A. Raabe
Objective: Microsurgery within motor cortex is a controversial approach due to the high-risk of permanent motor deficit. Few data exist showing the relationship between the mapping stimulation intensity required for eliciting a muscle motor evoked potential (MEP) and distance to the motor neurons; furthermore,[for full text, please go to the a.m. URL]
