Dear SPM99 experts,
I need your help.
I have subjected 6 patients to fmri with the same visual stimulus:
I am looking for a particular region of activation (V5 or MT complex).
I have analysed my data by Stimulate software and I have found two areas which I
was looking for.
When I analyse my data by SPM software I have a problem.
If I set high pass filter (default) and low pass filter (hrf) I don't find area
of activation except for one patient. Instead if I don't use high and low pass
filter I succeed to detect the two areas in all patients.
I think that is correct to use high and low pass filter but I lose true areas of
activation: I am very puzzled.
Thank you in advance for your help.
