Abstract

In order to clarify the information processing of calculation in a brain, the event-related potentials (ERPs) elicited during the calculation task were measured. However, the ERPs associated with calculation were small amplitude, and the latency of it were unknown. Then, a new method named the sequential difference method was introduced, and succeeded to detect the signal clearly. The detected calculation-relevant waveform appeared followed the P3 in the opposite polarity. The distribution of the ERPs associated with calculation on a head were analyzed by the topography. The results showed that the responsible area for calculation was parietal region in the left hemisphere of the brain
