The present authors and his collaborators have been investigated into recorded electro- encephalograms (EEGs), especially the event related potentials (ERPs), from subjects viewing many type of visual stimulus. In this series of research, the equivalent current dipole source localization (ECDL) method has been applied to these ERPs. The method enables to localize the origins of electroencephalograms (EEGs) measured from subjects as ECDs. The paper introduces a confidential region, which is implemented with the ECDL software; SynaCenterPro (NEC Corporation). The confidence limit is defined on a direction of the radius. The method improves spatial resolution of EEG measurement, which has an advantage of temporal high resolution against other studying apparatus for functions of the human brain.
