初级运动区的fMRI实验研究

Primary Motor Cortex Is Not a Single Function Unit——Clustering Results from fMRI Experiment Data

本实验采用功能磁共振为实验仪器,被试进行运动准备和运动执行两种作业活动,实验设计为延时序列运动任务。在对实验数据进行预处理,反卷积,标准化处理后,采用欧式距离公式进行聚类统计,统计结果显示,M1区不仅具有运动执行和运动准备的功能,还发现其他功能区域的激活,不是单纯的运动执行功能,这一区域与三种活动有关。

Using functional magnetic resonance imaging （fMRI）, and administering to the subjects of motor preparation and motor execution activation, and processing the data of experiment clustering statistics, the authors studied various functions in the area of M1. We reach the following conclusion： In addition to its motor preparation and motor execution, the area of M1 has three kinds of function activations. It isn＇t a single function .
