The authors have recorded electroencephalograms (EEGs) from subjects viewing four types of Kanji and arrows representing directional meaning. Subjects were asked to read them silently. The equivalent current dipole source localization (ECDL) method has been applied to these event rerated potentials: averaged EEGs. ECDs were localized to the right and left frontal lobes at latency after 500ms in both cases. Polarities of ERPs were also opposite in the case of opposite directions, and the moments of localized ECDs at these latencies were opposite. Pathways in silent reading are almost the same in cases of Kanji and arrow. In these cases, ECDs no ECD was localized to the Wernike’s area and the angular gyrus those are related to the auditory language area, however, ECDs were localized to the Broca’s area which is said to be the language area for speech. By use of the results, an application to Brain Machine Interface had been tried.
