Dear all,
We have done an fMRI experiment with young and elderly subjects performing
two different motor tasks. The paradigm is a blockdesign with rest 40s,
first activation 32s, rest 48s, second activation 40s and rest 56s. I would
like to perform a 2 way ANOVA in SPM to study the interaction effect of age
and performance of the two tasks. How should we choose the right contrasts?
Regards,
Patrizia
