It’s difficult for doctors to help a person with a hurt brain. enough blood, the brain can live only 3 to 5 minutes. Usually doctors can’t fix the hurt such a short time.
Dr Robert White thinks he knows a of help. He thinks doctors should make the hurt brain to live for 30 minutes without blood. This gives the doctor time to do something for the brain. Dr White experimented his on fifteen monkeys. he taught them to do different jobs. Then he operated on them. He made the monkeys’ blood go a machine. When the brains’ was 10℃,he stopped the blood to the brain. After 30 minutes, he turned the blood back on. He the blood again. After their operations, the monkeys were almost before. They were healthy and busy. Each one could still do the job the doctor them.
Dr White’s idea works well on monkeys. He thinks it will work on . He thinks it will help with heart problems. A person die when his heart stops; doctors can it again. The problem comes: when the brain is without blood for about 5 minutes, it . If doctors start the heart again after 5 minutes, the person has body but a dead brain. Maybe in the future, doctors will Dr White’s idea. When the person’s heart stops, the doctor will cool the brain. They will have 30 minutes to start the heart again. Maybe there will be no the brain.

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, and 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.
