Wfe recorded event-related potentials (ERPs) by electroencephalography (EEG) during fuzzy and crisp calculation. Questions are divided into 2 types. As type A, questions were presented as sentences. Questions of type B were presented as numerical calculation. In type A, the peak latency of the EEG was around 1100ms. In type Bt the peak latency was around 650ms. In type A, from multiple equivalent current dipole source localization (ECDL) around the latency, it followed that sources during fuzzy calculation lie in the right hemisphere and that sources during crisp calculation lie in the left hemisphere. In type B, no significant difference was observed.
