Abstract
Summary form only given. Magnetoencephalogram (MEG) measurement of the magnetic field perpendicular to the scalp is widely used. We carried out the measurement of magnetic alpha waves using a 195ch whole-head vector MEG system for detecting three magnetic field components (B/sub r/, B, B). In order to discuss the multiple sources of the magnetic alpha wave, a source estimation algorithm with singular value decomposition method we developed by Kobayashi and Uchikawa (2001) was used.
