     It is difficult for doctors to help a person with a damaged brain. Without enough blood, the

brain lives for only three to five minutes. More often the doctors can't fix the damage. Sometimes

they are afraid to try something to help because it is dangerous to work on the brain. The doctors

might make the person worse if he operates on the brain.                                                            

     Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks

doctors should make the brain very cold. If it is very cold, the brain can live without blood for

30 minutes. This gives the doctor a longer time to do something for the brain.                                  

      Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he

operated on them. He made the monkeys' blood go through a machine. The machine cooled

the blood. Then the machine sent the blood back to the monkeys' brains. When the brain's

temperature was 10°C, Dr. White stopped the blood to the brain. After 30 minutes he turned

the blood back on. He warmed the blood again. After their operations the monkeys were like

they had been before. They were healthy and busy. Each one could still do the jobs the doctor

had taught them.
