Multi linguistic Neuronal Processing fMRI Study

功能性磁共振成像（MRI）彻底改变了人类大脑高级功能的研究。然而，该方法仍然具有各种缺点。该项目旨在开发一种更好的算法来研究语言处理，并反过来利用专门为fMRI实验优化的高场MRI系统（包括垂直3T MRI系统）来阐明人类语言功能的神经元基底。语言处理的大脑策略，特别是那些与阅读有关的能力，被发现受到一个人最初获得读写能力的语言结构的显著影响。左侧颞下沟（ITS）后部两侧的皮层是汉字阅读等复杂字符处理所必需的，而舌回则是音节形成的高度特异性区域。左侧梭状回是所有语言的“共同”区域，右侧枕横回是音符或手语等位置加工所需的区域。声音的感知在触发大脑组织“语言通路”中起着重要作用，尽管它作为语言的有效传递属性。自组织原理和“抽取”原理是包括阅读在内的视觉信息处理的基本特性。

Functional magnetic resonance imaging (MRI) has revolutionized the investigations of higher brain function in humans. Nevertheless, the method still has various shortcomings. The projects are designed to develop a better algorithm in studying language processing and, in turn, to elucidate neuronal substrates underlying functionality of human languages utilizing high-field MRI system specifically optimized for fMRI experiments including vertical 3T MRI system.Brain strategies for language processing, especially those related with reading are found to be significantly affected by the structure of the languages with which one's literacy is first acquired. The cortex flanking the posterior aspect of the left inferior temporal sulcus (ITS) is necessary for complex character processing such as Kanji reading, while lingual gyri are highly specific for syllabus formation. The left fusiform gyrus represents "common" area for any languages and right occipital transverse gyrus is needed for positional processing such as musical note or sign languages.Regardless of its effectiveness as language conveying property, the perception of sound play a significant role in triggering the brain to organize "language pathway." The principle of self-organization and "decimation" principle appear to be tia fundamental properties of visual information processing including reading.
