Data and scripts from:Ageing and the ipsilateral M1 BOLD response: a connectivity study By Yae Won Tak, Ethan Knights, Richard Henson and Peter Zeidman(Revision 1)Analysis of the Cam-CAN dataset using DCM for fMRI, investigating why right primary motor cortex (M1) has negative BOLD responses that decrease in amplitude with age.本研究的数据与代码脚本源自：《衰老与同侧初级运动皮层（ipsilateral M1）的血氧水平依赖响应（BOLD response）：一项脑连接研究》，作者为Yae Won Tak、Ethan Knights、Richard Henson与Peter Zeidman（修订版1）。本研究采用功能磁共振动态因果建模（DCM for fMRI）对剑桥衰老与认知老化项目数据集（Cam-CAN dataset）开展分析，旨在探究右侧初级运动皮层（primary motor cortex, M1）出现随年龄增长而振幅降低的负向血氧水平依赖响应的成因。
