In the measurement of brain function by using fMRI, increasing of blood flow and decreasing of de-oxy-hemoglobin concentration as a cause of this increasing (BOLD: Blood Oxygenation Level-Dependent) are measured. And brain activity is evaluated as the function of BOLD signal. In the f-MRI measurement, MRI data under stimulation and resting are measured periodically, and these data are compared and analyzed. This measuring method is usually used. However, periodic stimulation sometimes produces experience. And this experience may weaken the brain activity. Therefore, in order to suppress experience, fMRI was measured using fluctuated stimulation. And the results of this measurement were compared with the data that was measured using ordinary method.
