说汉语普通话者讲话时同时使用大脑两边

- F9 }) f+ B" j. J; F1 _英国的研究人员发现，说汉语普通话的人可能比说英语的人用更多大脑。研究表明，说汉语普通话者讲话时同时使用大脑两边。
说英语者只使用大脑一边。研究人员说，这项研究能够促进了解大脑处理语言的过程。
另外，这项研究还可以帮助研究人员找到更好的办法，帮助人们在中风或者脑部受到类似损害后重新学习，掌握语言技能。
在这项研究中，操汉语普通话和操英语的两组人接受脑部扫描。研究人员发现，人们讲英语时，靠近左太阳穴的左颞叶开始活跃。
; f( Z1 {; q! z他们发现，大脑这个区域的功能是把发音联系起来，形成单个词汇。
, g) y6 Y& A+ ?# @8 @研究发现，人们说汉语时，左颞叶和右颞叶一起活跃。研究人员说，说不同语言时，人的大脑在以不同方式破译语言。这就推翻了长期以来的看法。
5 e' }/ `8 R: ^& u- X1 i7 i# t$ O汉语普通话十分难学。不同于操英语者，说汉语者使用音调区分不同词的不同意思。比如"马"音，用不同音调发音，可以是马，妈等不同的意思。

Chinese 'takes more brainpower'

Speaking Chinese may take more brainpower than speaking English, a study suggests.

This, in turn, could one day help scientists to develop better ways of helping people to re-learn languages after a stroke or similar damage to the brain.

Brain scans

Dr Sophie Scott and colleagues at the Wellcome Trust carried out brain scans on a group of Mandarin and English speakers.

They found that the left temporal lobe, which is located by the left temple, becomes active when English speakers hear English.

"People who speak different sorts of languages use their brains to decode speech in different ways," said Dr Scott.

# @7 t6 x7 ?  E( r' c4 E+ [Mandarin is a notoriously difficult language to learn. Unlike English, speakers use intonation to distinguish between completely different meanings of particular words.

8 X* L* F8 b. AFor instance, the word "ma" can mean mother, scold, horse or hemp depending on how it is said.

The researchers believe that this need to interpret intonation is why Mandarin speakers need to use both sides of their brain.
