PROBLEM TO BE SOLVED: To cause eye fixation related potential or a representative value extracted from it to be displayed in a way easy to view in a short cycle of renewal, for plural parts of the brain. SOLUTION: An eye-movement end point detecting part detects the end point of a saccade (rapid eye movement) on the basis of an eye-movement signal and supplies its signal to a primary storage part 4. Each time a saccade ends, the primary storage part 4 stores brain waves consecutively as unit brain waves within a certain period of time from the end point of the saccade, for plural parts of the brain. Each time a saccade ends, a computing part 5 computes, for each of the plural parts of the brain, the average of the unit brain waves stored in the primary storage part 4. |
