摘要:利用功能性磁共振成像(fMRI)的方法,实验通过组块(block)设计,对对照组和实验组的被试分别为性别,年龄和教育水平相匹配的10人进行脑部成像,对所有的图像进行数据处理,结果显示焦虑症患者和正常人相比,在某些特殊位置的功能性的异常,得到了和焦虑症神经病理机制相关的特异性脑区,提出了恐惧通路的假设。

Research of anxiety disorder with BOLD fMRI
Abstract:In this paper,control group and experiment group,including 10 people whose gender,age,education level were matched. Based on the methods of fMRI and block design, we got the brain images of these people , then processing all the image date.The result reflected that there were some functional abnormal in several special positions,when comparing with the control group . These special abnormal brain regions were related with anxiety disorder neural mechanism,and put forward the hypothesis of fear pathways.
