(15)　ファジィ計算とクリスプ計算に関わる脳内部位　-双極子解析による推定-
　　　　　　　第１７回ファジィシステムシンポジウム講演論文集pp.281-282,2001-9

　The authors recorded 19ch event-related potentials (ERPs) during fuzzy and crisp calculation presented by sentences on CRT. The calculation was invoked by 60 questions. The subjects were requested to input the answers by a keyboard when they finished calculations. We investigated differential waveform between fuzzy and crisp calculations to determine the latency of ERPs. From multiple equivalent current dipole source localization (ECDL) around this latency of each ERPs, it followed that sources during fuzzy calculation lie in the right hemisphere and that sources during crisp calculation lie in the left hemisphere.
