NEW YORK (Reuters Health) - The typical brain activity that occurs when most people are resting or daydreaming is impaired or absent in individuals with autism, new research suggests.

The activity in this so-called "resting network" normally aids in the processing of emotional and social cues, "the very things that are abnormal in autism," lead investigator Daniel P. Kennedy noted in comments to Reuters Health.

The resting network is known to be highly active when an individual is at rest.

When someone is asked to perform a mentally demanding task that is not of a social or emotional nature -- like a math problem -- the resting network shuts down or is deactivated, "most likely reflecting a reduction in these unconstrained resting thoughts," explained Kennedy, a graduate student in the neuroscience PhD program at the University of California at San Diego in La Jolla.

Kennedy, along with Elizabeth Redcay, a UCSD graduate student in psychology, and Eric Courchesne, also at UCSD, report their findings in the Proceedings of the National Academy of Sciences, Early Edition.

Through brain imaging, Kennedy and his colleagues saw that the resting network of the autistic brain does not deactivate, likely because this high resting activity is not there during rest.

"We think that this finding makes sense in terms of understanding the social and emotional aspects of the disorder," Kennedy said. "We found that a network of brain regions important for social and emotional processing is abnormal in a disorder of social and emotional processing," he said.

The scientists also observed that the more abnormal the resting brain activity in the medial prefrontal cortex appeared, the more socially impaired the autistic subject was. Therefore, "it does seem that there is a clear relationship between this resting network and social impairment in autism," Kennedy said.

下面引用由小钦发表的内容：

我通过长期的观察也发现,自闭孩子一般是无法按要求闭上眼睛"假寐"片刻,或闭眼"暇想"的,

我儿子也不能做到这点.现在他在游戏时,可以有意识地闭一下眼睛,很短暂而且面部表情特怪.

小钦老师提到左右脑额叶,让我想起以前听过的讲座里也提到左右脑皮层不能互通的问题(Latéralisation),我现在也和儿子做些帮助左右脑沟通的小运动.
  
其实现在大多数有关自闭症的研究都趋向于脑神经学研究和基因学研究,这些研究发现可以让社会更好的认识有自闭症的人群,正确认识他们的价值,尊重他们的差异.

我爱我儿,谢谢你那么快就翻译出来.

本来回了一个贴子感谢你的帮忙,刚发现和你的"delete"贴子一起被撤掉了.不知你看到没?真的很羡慕你翻译得那么流畅,希望以后还可以得到你的帮忙.
