CEREBRAL LANGUAGE ORGANIZATION IN CHILDREN WITH AUTISM SPECTRUM DISORDERS

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。这项研究的目的是确定当一个人在执行识别特定单词的任务时，当两个不同的单词同时出现或每只耳朵有一个稍微延迟出现时，大脑的哪些部分变得活跃。这个过程将帮助我们了解有学习障碍的儿童和没有学习障碍的儿童在大脑功能上是否存在差异。这项研究涉及一个实验性的磁共振成像（MRI）扫描仪，它是一个大磁铁，作为一个连接到计算机的管道。磁铁产生不同频率的磁场，计算机能够将返回的电磁波转换成图像。这使我们能够看到大脑对一个人可能执行的许多不同功能的反应，比如看、记忆或移动身体的某些部位。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The purpose of this study is to determine what parts of the brain become active while a person performs the task of identifying a particular word when two different words are presented simultaneously or with a slight delay, one in each ear. This procedure will help us understand whether there are differences in brain function between children who have learning disability and those who do not. This study involves an experimental magnetic resonance imaging (MRI) scanner which is a large magnet built as a tube connected to a computer. The magnet produces magnetic fields at different frequences and the computer is able to translate the returning magnetic waves to pictures. This allows us to see the response of the brain to many different functions a person may be carrying out , such as seeing, remembering or moving parts of the body.
