I have normal subjects. (high res sag anat, spiral sag functional)
I rotate my images (Anat & Func) to appropriate SPM orientation, I realign
functionals, then I coregister my anat to my functionals. I use the T1 template
to normalize my anat and then then apply those parameters to my functionals.
Smoothing of course (10mm).
When I run stats and bring up my functional contrast at uncorrected 0.999 to see
how well my functional data looks within the glass brain, I get some frontal
"mickey mouse" activation [see attached] I've never seen, before outside the
brain, and this is happening with multiple subjects (~8)
how do I correct this?
Do I need to change normalization parameters in the defaults, and which ones?
should I mask?
sorry for such simple questions but I've never seen anything like this,
thanks, sophie
