A brain function activity of a subject is measured using a brain function measuring unit by presenting multiple stimulations, which are adjusted to have no cognitive meaning when presented in a separate manner and to have a cognitive meaning when presented simultaneously as a combined stimulation, to the subject as the combined stimulation at regular intervals with a control of a control unit, thus measuring a higher cognitive brain activity responding to the combined stimulation separately from a lower cognitive brain activity.
