Dear SPM gurus:
Please allow me to ask advice for analysis of my data. am sorry that it may
be basic but I have no idea at all. I am also sorry about that I did not
have sufficient time to follow the mail discussion. I would appreciate if
anyone can give me some advice or references.
I have 10 subjects, each have two sessions, each session has two condition.
so it is A1-B and A2-B. The B is the same for two sessions. Subject had
psychophysical score to A1 and A2, respectively.
I used random effect analysis. For each subject, I have two contrast,img,
i.e. con(A1-B).img and con(A2-B).img.
Then I used one sample T test to get a SPM of con(A1-B), and a SPM of
con(A2-B), and use paired T test to get a result of (A1-B) vs (A2-B).
Thalamus showed activation on all the three SPMs.
Now I would like to know
1. the relationship between psychophysical score and activation of thalamus.
2. the relationship between activation of thalamus and S1.
How should I do?
Sincerely
Ming-Ting
