A brain response measurement system includes a stimulation timing control unit calculating, based on a delay time from a brain response to first stimulation in a first brain area to a brain response to a second stimulation in the first brain area, and a delay time from a brain response to the second stimulation in the second brain area to a brain response to the first stimulation in the second brain area, start and end times of the first stimulation and start and end times of the second stimulation that cause the brain response to the first stimulation in the first brain area and the brain response to the second stimulation in the first brain area not to overlap and cause the brain response to the second stimulation in the second brain area and the brain response to the first stimulation in the second brain area not to overlap.
