Abstract

We explored spatiotemporal brain activation patterns during perception of words from three different languages (Korean, English, Chinese) and pictograms, using 64 channel recording of event-related potential (ERP) and source localization using distributed source model. We investigated, with high temporal resolution, whether similar or different spatiotemporal patterns of brain activation are involved. The results seem to corroborate recognized left hemispheric dominance in language processing, and temporal/spatial characteristics in word perception. Observed differences in spatial activation pattern at specific time periods between English and Korean, and Korean and Chinese, could be explained in terms of required visual pattern analysis due to the orthographic characteristics
