Our recent clinical experience of the whole head magnetoencephalography (MEG) is summarized in this paper. We applied a multimodal functional brain mapping technique, using a newly developed helmet shaped 64 channel MEG system. This system enabled us to measure evoked magnetic fields over the entire head simultaneously. MEG is completely non-invasive. The whole head MEG is suitable for patients with severe neurological deficit because of a short measurement time. Signal sources, localized by a multiple current dipole model, were superimposed on anatomical MR images of each patient.
