Our listener question this week comes from Abdullahi Farah, who wants to know about the life and work of Doctor Benjamin Carson.

Doctor Carson is an internationally recognized doctor at Johns Hopkins Hospital in Baltimore, Maryland. He has been the director of Pediatric Neurosurgery at the hospital for twenty-five years. At the age of thirty-three, he became one of the youngest doctors in the United States to hold that position. And he was the first African-American to have that position at Johns Hopkins Hospital.

Ben Carson is known for his work as a brain surgeon for children. For example, in nineteen eighty-seven, he led a team of seventy doctors and nurses in an operation to separate two babies joined at the head. Earlier attempts by other surgeons on other babies had failed. Doctor Carson successfully performed the operation. Both babies were able to survive independently.

Doctor Carson has written four books. His first book, "Gifted Hands," tells the story of his life. Benjamin Carson was born in nineteen fifty-one in Detroit, Michigan.

As a boy, Ben was not a good student. In fact, he was the worst in his class. When his mother learned of his failing grades she asked her sons to read two library books every week. She limited the amount of time they watched television. And she told them to respect every person.

Ben Carson soon became the top student in his class. He went on to study at Yale University, one of the best universities in the country, and later to medical school at the University of Michigan.

Doctor Carson has received many awards and honors. Last year he received the nation's highest civilian honor. Former President George W. Bush presented Benjamin Carson with the Presidential Medal of Freedom at a ceremony at the White House.

Looking for a low-cost path to self-knowledge? A way to mine your subconscious (潜意识的) for clues to your motivations, desires and fears? No need to have years of treatments or analyses. Just look to your dreams.

“You can ignore your dreams, but you are really doing harm to yourself,” says Lauri Quinn Loewenberg. “If so, you're letting red flags pass you by, letting great ideas pass you by.”

Some sleep researchers believe dreams are more directly related to our moods and emotions and can serve as tools to self-understanding. Dreams occur during the REM (rapid eye movements) cycles of sleep each night. For adults, that means about every 90 minutes. The first period of REM sleep may be short, 5 to 10 minutes, followed by longer periods, finally reaching an hour or more in the fourth or fifth period.

When people are dreaming, brain scans show a lot of activities. The brain is online during dreams. The experiences you have during the day are connected during dream sleep. People we know or experiences we've had at different times in our lives may be different in the same dream.

AmyBeth Gilstrap has had the same recurring(再次发生;循环) dream that annoyed her since Hurricane Katrina drove her and her daughter and friends out of New Orleans. Mrs. Gilstrap says, “It is always spies. My job is to get people to some place.” She's certain the dream is related to her efforts in the hurricane to help several families leave. Sometimes her cats also are part of that dream. That's because she went back into New Orleans, before it was allowed, to rescue her cats.

Today, through brain scans scientists have known that the parts of the brain that control emotions and long-term memories are active during the REM sleep.
