Using a new form of brain imaging known as diffusion tensor imaging (DTI), researchers have found that the white matter in the brains of individuals with autism has lower structural integrity than in the brains of normal people. This provides further evidence that the anatomic differences characterizing the brains of individuals with autism are related to the way their brains process information.
The findings of this latest study are soon to be published in the journal NeuroReport. The scientists, from the Center for Cognitive Brain Imaging at Carnegie Mellon University (Pittsburgh, PA, USA; www.cmu.edu), utilized a magnetic resonance imaging (MRI) technique, DTI, which tracks the movement of water through brain tissue, to measure the structural integrity of the white matter that acts as cables to wire the parts of the brain together. Typically, water molecules move, or diffuse, in a direction parallel to the orientation of the nerve fibers of the white matter. They are helped by the coherent structure of the fibers and a process called myelination, in which a sheath is formed around the fibers that speeds nerve impulses.
The movement of water is more dispersed if the structural integrity of the tissue is low – i.e., if the fibers are less dense, less coherently organized, or less myelinated – as it was with the participants with autism in the Carnegie Mellon study. Investigators found this dispersed pattern specifically in areas in and around the corpus callosum, the large band of nerve fibers that connects the two hemispheres of the brain.
Dr. Marcel Just, director of the Center for Cognitive Brain Imaging and a co-author of the latest study, remarked “The new findings also provide supporting evidence for a new theory of autism that attributes the disorder to underconnectivity among brain regions.”
In 2004, Dr. Just and his colleagues proposed the underconnectivity hypothesis based on a groundbreaking study in which they discovered abnormalities in the white matter that suggested a lack of coordination among brain areas in individuals with autism. This theory helps explain a paradox of autism: Some people with autism have normal or even superior skills in some areas, while many other types of thinking are chaotic.
The latest research is providing a comprehensive image of the autistic brain, whose components operate with less coordination than is generally the case, and which is less reliant on frontal components and more reliant on posterior components. The latest DTI finding shows that some of the frontal-posterior communication fiber tracts are abnormal, consistent with the lower level of frontal-posterior coordination. | Translation - Chinese
DTI揭示自闭症患者大脑的差异
研究者用一种叫弥散张量成像(DTI)的新型脑成像技术发现，自闭症患者大脑白质的结构完整性低于正常人的大脑。这进一步证实了自闭症患者大脑解剖结构上的差异与他们大脑处理信息的方式有关。
这项最新的研究发现将很快发表在《NeuroReport》杂志上。卡内基梅隆大学(Pittsburgh, PA, USA; www.cmu.edu)认知脑成像中心的科学家利用DTI这种磁共振成像(MRI)技术追踪大脑组织中水的运动，以此来测量白质的结构完整性，而白质就像电缆一样把大脑的不同部分连接起来。一般来说，水分子运动（或称弥散）的方向平行于白质神经纤维的走向。连贯的神经纤维结构和髓鞘形成这一过程有助于水分子运动。髓鞘形成是指在神经纤维周围形成一层鞘，它能加速神经脉冲。
如果组织的结构完整性较低，即纤维较松、组织结构较不连贯或髓鞘形成程度较低——卡内基梅隆大学研究的自闭症患者就是这种情况，水的运动就更分散。研究人员发现，这种分散的模式主要见于胼胝体内部和周围的区域。胼胝体是连接大脑两个半球的粗大神经纤维束。
这项最新研究的合著者之一、认知脑成像中心主任Marcel Just博士表示：“这些新发现还提供证据支持了一种关于自闭症的新理论，即这种疾病可归因于大脑区域间的连接程度不足。”
2004年，Just博士和他的同事在一项开创性研究中发现了自闭症患者白质中的异常，这意味着他们的大脑区域之间缺乏协调。基于这项研究，他们提出了连接程度不足的假说。这一理论有助于解释自闭症的一个悖论：有些自闭症患者某些大脑区域的功能正常甚至超常，而许多其它类型的思维一团糟。
这项最新研究全面揭秘了自闭症患者大脑的情况，他们的大脑区域比正常人的协调性差，这更多地依赖于后部而不是前部。最新的DTI结果显示，某些司前-后通讯的纤维通道异常，印证了前-后协调性差。 |

I am a Chinese native currently living in Beijing. My education background is in Biomedical Engineering with emphasis in computer and electronics. That is why I claim my fields of expertise in medical instruments, medical general as well as computer software, information technology and electronics. Before I had 2 years of academic experiences and 3 years of industry experiences in the United States. I started my career as an engineer and switched to international marketing not long ago, all in medical device industry. In parallel with my mainstay business, I served as editor for HospiMedica Chinese Edition, published by Globetech Publishing Group (www.medinews.com), from the year of 2002 up to now. Through those valuable experiences I acquired in-depth understanding of technical English and developed superior bilingual skills. You can count on me for your technical documents such as product brochures, manuals and ads. I am committed to accurate, authentic and easy-to-read delivery.
