Dear SPM experts,
I want to include several parametric modulators in my fMRI design of
an explorative study. In general, I want to find out in which areas
the brain activity is modulated by each parameter (subjective
ratings). Partly these parameters are highly correlated.
My idea is to create several designs with the parametric modulators in
different orders and correct in the end for multiple testing with
Bonferroni. If I understand this correctly, I could look at the first
parametric modulators to see which variance is explained by it overall
and at the last one to check which variance is uniquely explained by
the last parametric modulator and not by any of the other ones.
Does this make sense?
Thank you very much for your help!
Regards,
Tanja
