Abstract(in English) This study is focused on the influences of spreading multiple dipoles in the head upon surface magnetic fields.Source model of the magnetoencephalogram(MEG)activity is proposed.This source model is expressed by spreading multiple dipoles which have time- varying dipole moments.Using this source model,spatio-temporal patterns of magnetoencephalograms(MEGs)are simulated.Effects of spreading dipoles on spatio-temporal magnetic fields are investigated.The computer simulation show that the waveforms and amplitude of magnetic fields are affected significantly by the spread of the source and the propagation velocity of excitation. The latency of the peak magnetic field generated by spreading multiple dipoles varies with the measurements points on the surface of head.
