Dear SPMer,
same situation as in my first mail, but from a slightly different point
of view:
I have scanned 16 subjects, belonging to 2 different groups (9 and 7
subjects, respectively).
During an activation task the first ("normal") group activates mainly in
one hemisphere, the second ("atypical") group in the other hemisphere.
Hypothesis:
The "atypical" subjects activate "typical" areas in their subdominant
hemisphere, i.e. the same areas that are activated by subjects from the
"normal" group.
What is the best way to adress this question?
I could do the following:
1. Do a fixed-effect analysis for both groups (my group size is too
small for a random effect approach)
2. Use inclusive/exclusive masking...
Is there a better appraoch?
What about a conjunction analysis for groups?
Any comments are appreciated,
Andreas
