Localization of brain activities during understanding Japanese honorific expressions by equivalent current dipole analysis

Abstract

Japanese texts with interpersonal meanings focused on honorific expressions and ideational meanings were presented to four subjects. In the meantime electroencephalograms (EEGs) were recorded, and equivalent current dipoles (ECDs) were localized to estimate the activated neuronal sources of EEGs. The experimental results showed two different dynamical routes in the brain common to all the subjects in understanding honorific expressions in contrast to texts with ideational meanings.
