| Abstract(in English) | The purpose of this study is to propose models in which both magnetoencephalogram(MEG)and electroencephalogram(EEG)activities evoked by color imagination are recorded simultaneously.The components of magnetic fields perpendicular to the surface of a head were measured by using a dc SQUID with a first-derivative gradiometer.We observed that both MEG and EEG activities were affected by color imagination.The power spectrum of MEG evoked by color imagination showed a single sharp peak at 11 Hz.In contrast, the power spectrum of EEG showed broad patterns.The EEG topography showed that the spectrum component at 1 1 Hz dominated in the occipital region.On the basis of the results,we proposed two- dipole model whose directions vary with time to explain the change in EEG topogra-phy evoked by color imagination. |
