  • Abstract
  • Look Inside

Authors compared MR anatomy and magnetoen-cephalographic (MEG) functional methods in locat-ing auditory cortex in 20 normal volunteers and 56 patients with intracranial structural lesions. Audi-tory evoked response was measured over the entire head, using a helmet shaped 64 channel MEG sys-tem. In each subject, three dimensional MR image was obtained with identical coordinate system of MEG. Best fit sphere to each subject's head was calculated from MRI data. Signal source of audi-tory evoked MEG was estimated using a two dipole model in the best fit sphere.
