Visually evoked magnetoencephalograms (MEGs) were recorded by using a whole-head-type superconducting quantum interference device (SQUID) system. The so-called P300 component was obtained by using the oddball paradigm, in which the object to be discriminated was a color. The electrical activities in the brain associated with the generator of the P300 component were estimated by using a 2-dipole model and examined.
