(3)With a team of colleagues (同事) at Tokyo National University, he set about measuring brain activity of a thousand people of different ages and varying (不同的) jobs. (4)Computer technology enabled the researchers to obtain precise measurements of the activity of the front and side sections of the brain, which relate to intelligence and feeling, and determine the human character. (The rear section of the brain, which controls functions like eating and breathing, does not change with age, and one can continue living without the ability to think and feel.)
