RE: Voxel-to-voxel analysis regression models
Hi Emanuele,
Yes, it is possible and perfectly fine to use any form of mixed within- between- subject contrast on the ICC measures resulting from voxel-to-voxel analyses. In particular, you can use the same combination of between-subjects contrast [0,1] and between-conditions contrast [1 -1] on the ICC measures to explore the correlation between performance and intrinsic connectivity differences (ICC differences between your two sessions) at each voxel.
Hope this helps
Alfonso

Hi all!,
is it possible to apply the same multiple regression contrasts used in the seed-to-voxel analysis in the voxel-to-voxel ICC analysis?
In particular, I would like to look at the correlation between performance and connectivity variation (between two time points) in a given group from a given seed, and I would use the followingcontrast for a seed-to-voxel analysis:
[0,1] [1 -1]. Now, is it possible to apply the same contrastto and ICC-based voxel-wise analysis, since those are z-scores?
Thank you!
