脑科学和脑功能MR成像

目的：在对大脑认知功能进行脑功能成像研究之中，随着磁共振成像技术的发展，人们现在可以对脑的认知功能，如视觉、运动、语言和记忆等功能中枢进行成像。本文首先介绍了脑科学的发展历程，并从脑功能MR成像的方法出发，分析了其成像机理，探讨了用脑功能MR成像为手段对脑科学—认知科学进行的方法研究，最后对脑功能MR成像应用于脑科学的研究作了展望。

Brain Science and Function Imaging

With the current technical development of MRI,people can map a broad range of cognitive,such as vision,motor,language and memory in the brain entirely non invasively.In this article,we firstly introduce the history of brain science,we then analyse the principle of functional magnetic resonance imaging(fMRI),after that we focus on the method of study on the cognitive process of the brain,at last,we give a good prospect of the research.
