What happens inside the head of a soccer player who repeatedly heads a soccer ball. That question motivated a study of the brains of experienced players.
Researchers at the Albert Einstein College of Medicine in New York selected 34 adults, men and women. All of the volunteers had played soccer since childhood and now competed year﹣round in adult soccer leagues. Each filled out a detailed questionnaire developed especially for this study to determine how many times they had headed a soccer ball in the previous year, as well as whether they had experienced any known concussions in the past.
Then the players completed computerized tests of their memory and other learning skills and had their brains scanned. using a complex new M.R.I. technique which can find structural changes in the brain that can't be seen during most scans.
According to the data they presented, the researchers found that the players who had headed the ball more than about 1, 100 times in the previous 12 months showed significant loss of white matter in parts of their brains involved with memory, attention and the processing of visual information, compared with players who had headed the ball less.
This pattern of white matter loss is "similar to those seen in traumatic brain injury", like that after a serious concussion, the researchers reported, even though only one of these players was reported to have ever experienced a concussion.
The players who had headed the ball about 1, 100 times or more in the past year were also generally worse at remembering lists of words read to them, forgetting the words far more often than players who had headed the ball less.
Amazing Movies
Are you looking for some movies? You've landed on the right place. Let's take a look at the list I've collected.
A Beautiful Mind A Beautiful Mind is the story of John Nash, a mathematician who went on to win the Nobel Prize for his Game Theory. This movie brings his whole journey on screen—from his beginning to his downhill ride. The first half is all about his rise to fame while the second half shows how he slowly falls into madness. After many years of fighting, he finally is victorious. |
I. Q. The story is about an auto mechanic who falls for Albert Einstein's niece. The only problem is that she is engaged (订婚) to someone else. Fortunately, Einstein likes him. He pretends to be a physicist to run after her, but things don't go as he'd planned. If A Beautiful Mind was a little too heavy for you, I.Q. would be the perfect fit. It's a light-drama that is funny and heartwarming for the most part. |
Good Will Hunting Good Will Hunting is a touching tale of a troubled young man called Will Hunting who is gifted with a natural talent in mathematics. However, he is struggling to find his identity. He can solve any math problem, but not the one he seems to be struggling with in his life. His life seems to be getting only worse until one day he meets Sean, a therapist, who helps him find direction in life. |
Creation Creation is a story of famous scientist, Charles Darwin, best known for his evolution theories. This movie attempts to bring his struggling days into focus; the time when he was dealing with the loss of his daughter and was suffering from hallucinations (幻觉). At the same time, he was working on a book called On the Origins of Species, which he finally completed. All in all, Creation is a great historical drama. |
