Dear SPM colleagues,
Some of you may have read the recent comment and controversies in
NeuroImage. Using spm_regions I extracted both mean signal (non
adjusted) and 1st eigenvalue from two ROIs. In the fist ROI the plots
are similar whereas in the second one I have differences. Does someone
have an idea if showing the plot is enough to assert that one region
shows homogeneous response and not the other? or can I statistically
compare the results with a t-test (the mean activity being different)?
If u have other idea to show that ..
Thanks
Cyril
