Abstract(in English) | The N400 effect is well known that semantic violations elicit a negative potential that peaks approximately 400ms after stimulation onset in EEG studies, and it is also elicited by arithmetic incongruent equations using EEG. The research, however, the source location of the N400 effect was not clear because of EEG's ability. In this study, the source location of the N400 effect during incongruent multiplication problems was examined using a 160-channel whole-head MEG system by Eagle Technology Inc., Japan. Results from 10 participants' data indicate that the N400-like effect was observed between 370ms and 448ms, and equivalent current dipoles (ECD) for N400m were mainly localized to the left superior temporal region. |
