  • Abstract
  • Look Inside

In the present study, we evaluated the usefulness of magnetoencephalography (MEG) for presurgical identification of not only the central sulcus by somatosensory evoked magnetic fields (SEFs), which is a well-known, reliable tech-nique, but also the primary hand motor area by movement-related cerebral magnetic fields (MRCFs). Subjects were 10 patients with brain tumor (6 glial tumors, 3 cavernous angiomas, and 1 metastatic tumor) around the sensorimotor area.
