ALFF

Submitted by krishna.dani on Wed, 05/05/2010 - 23:10

Dear RESTers

I am new to REST and to SPM. I would be grateful for any advice.

I have resting state fMRI data (3mins, TR 3s) and I am keen to look at the ALFF in a lesion and on the contralateral hemisphere to detect any differences. For each of my scans the lesion is in a different place, difference size, and may affect either hemisphere.

If I generate the ALFF map and calculate the mean ALFF value in lesion and in a mirror region is this valid or would higher level statistics be more appropriate?

Thanks

Krishna
