questions related Rest Alphasim

Dear experts,

    I'm now doing some task-fMRI analysis about the group difference between internet disorders and health controls. Since no regions of ROI could survived FDR correction for multiple comparisons using a small volume correction, I've tried the REST's AlphaSim program for whole-brain and small volume correction. And I'm not sure whether my manipulation was right, and I’d like to ask for your advice.

rs-fMRI sensitivity

Submitted by crirosazza on

Dear Dr. YAN Chao-Gan and experts,

I kindly ask you if you know studies that investigated the sensitivity of the rs-fMRI technique in the clinical setting, such as AD.

In particular I have been looking for studies with a large number of patients which possibly used the Receiver operator characteristic (ROC) analysis to assess the diagnostic power of the rs-fMRI technique.

Thank you for your help,

Cristina Rosazza
