Thu, 11/15/2012 - 22:12287391600老师: 您好! 请教老师这样的问题:我之前用的是种子点的功能连接方法,得出病人组和正常组差别不大,但是后来我改用ICA的方法得出的结果是病人组的有比较明显的减弱的区域,所以这两种方法的结果有矛盾的地方,这让我该怎么往下进行呢? 谢谢!9999 reads

Tue, 11/13/2012 - 19:45wisepig119您好,严老师,我是精神科的医生,对VMHC很感兴趣,想做一些VMHC在精神障碍患者静息态的研究,但是由于之前我们并没有采集T1的结构数据,我看由于大脑结构的不对称性,很多都根据被试的结构数据做模板,再将功能相配准到结构相,而我没有T1结构可以做VMHC吗?对结果又有哪些影响呢?盼望您的解答,谢谢!10130 reads

Sat, 11/10/2012 - 18:11yangshuo老师您好 我想请问一下功能连接的Z值的问题: 1、例如AD-NC双样本T检验在某个CLUSTER上t值为正值,说明AD比NC增强的正连接、或者降低的负连接,我怎么分别确定AD和NC的连接性质,是把坐标回输到AD和NC各自的单样本T检验去看吗? 2、组内的单样本T检验的正z值说明功能连接是正连接、负Z值说明功能连接是负连接吗? 3、如何获得在这个有显著差异团块的平均Z值?我用团块的peak点坐标分别回输到AD组和NC组的单样本T检验图像里,...14120 reads
