The authors recorded nineteen-channel event-related potentials (ERPs) during recalling one type of Japanese character; Kanji (Chinese characters). A word was presented to the subject. Each word consists of some Hiragana characters (one type of phonetic characters), and the words has some corresponding Kanji homophones. Meantime ERPs were recorded on a PC. The equivalent current dipole source localization (ECDL) with three unconstrained ECD was applied to the ERPs. The ECDs for one left-handed subject were localized to the angular gyrus around latency of 410ms. After that ECDs were localized to the inferior temporal area around 460ms, to the hippocampus around 540ms and then to the Broca’s area around 600ms.
