Structural / Functional Connectivity - Literature Review

Submitted by kvoigt on

Hello,

I am searching for papers discussing the issue on structural connectivity might reflecting functional connectivity (e.g. Greicius, Supekar, & Dougherty, 2009; but not necessarily vice versa; Deco, Jirsa, & McIntosh, 2011).

If somebody made a similar search in the past, I am thankful for any reading suggestions. 

大脑和行为之间的关系

各位老师好！
 
我想请教一下各位老师，在fMRI研究中，应该如何来做大脑和行为之间的关系。
 
1， 在一般的高分和低分极端组设计中，似乎通常的做法是这样的：对两个组进行独立样本t检验，对有差异的脑区即ROI提取平均值，比如ReHo的平均值，然后分别在高分组和低分组内做ROI提取的平均值与某个量表的Pearson相关。但是这样做的效果我得到的不是很理想。有时候得不到显著的结果。有时候得到的结果甚至和独立样本t检验的结果互相矛盾。比如，在高分组中发现某个脑区的ReHo值高于低分组，然后组内的Pearson分析竟然发现它的ReHo值与量表得分呈负相关。我觉得可能的原因在于由于在一个组内做分析，样本量太少导致的。

Dear Resting experrts,

I am getting an error message with Matlab. I think that the problem is that I did not set the path correctly to the folder where I want the results.

First of all, I have downloaded and installed the toolkit in MATLAB in a Ubuntu (Neurodebian) environment.

老师您好：
      我用DPARSFA caculate in MNI space (warp by DARTEL);准备好相应的T1RAW和FunRaw; 包如下错误：

Index exceeds matrix dimensions.

Error in DPARSFA_run>(parfor body) (line 223)

Wrong ROI definition when extracting CSF/WM signal etc

Hello, I am receiving a bug when extracting the ROI signals (i.e white matter, CSF) for the nuisance covariates regression. The error appears after slice timing, realignment have been done. The error I received is below, I believe it is due to DPARSFA not being able to find the masks in the working directory. The error only appears with DPARSFA. My data was converted from DICOM --> NIFTI outside of DPARSF, then converted into spm format using freesurfers mri_convert to 208 indiviudal img files.

 各位老师们，同学们：
       我是这方面新手，最近在学习中，我在安装DPARSF中，总是报错，工具包无法加入matlab中，已尝试了各个版本的DPARSF，均无效。
       我使用的是rest v1.7和spm5。
       DPARSF尝试打开，报错如下：
??? Attempt to reference field of non-structure array.
