In the human brain, the logical process is performed in the left hemisphere and the intuitional process is performed in the right hemisphere. We recorded event related potentials (ERPs) by the electroencephalograms (EEGs) during subjects were performing selections of an answer. The subjects were 7 normal university students (4 males and 3 females; aged 21-22 years; 6 right-handed and 1 left-handed). They were asked to add double figures and select an answer from the two choices. Choices were two types; Type1 was correct choice that the correct answer was included, and Type2 was approximation choice that the correct answer was not included. By using the equivalent current dipole source localization (ECDL), we compared brain activities in the meantime.
