No joke: Learning to juggle can cause changes in human brain structure,say researchers at the University of Regensburg in Germany.At the start of their stydy, the scientists performed brain scans on 24 volunteers with no juggling ability. Then they gave half the group three months to learn how to juggle three balls for at least 60 seconds.After the practice period,brain scans of the12 jugglers showed more gray matter--brain tissue related to processing information—than non-jugglers. The catch: When the jugglers stop tossing the balls for another three months, the amount of gray matter returned to normal. “Our results challenge our view of the human central nervous system (brain and spinal cord),”The lead researcher Arne May said. Traditionally, scientists have believed that the adult brain does not change after new experiences. May suspects that juggling could change how brain cellls are made or connected. He hopes his studies will eventually help treat brain diseases.

大致意思就是说，练习那种杂技的颠球（轮流抛3个球的那种..）可以改变脑部结构，增加脑部和脊髓灰白质的数量……好像是这么回事情。。灰白质主要又是有神经细胞构成。。。（说错了表打我啊……）

忘了有没有在我们课文中出现过

晕 没用 要是有用的话抡不到你在这发表了， 早就能制这个病了正常人抛三个球都很困难 何况亚也呢

错，像我这样的正常人抛两个球都是很不易

如果在得病的初期。。还是可以做到的么。。。
