Dear SPMers,
I have ran a two-tailed t-test using SPM8 with pediatric brains. I was wondering if there is a standard extent threshold that should be used for structural analysis?
I have played around with some of the settings and have found activation, but am uncertain what this means exactly. Does this mean that there are more voxels being activated in this group than in the other group? Is there a larger number of voxels in this area or is there a completely different interpretation of this altogether? Any help will be much appreciated
Thank you,
