Hi,
In our functional MRI studies, we co-registration the functional
images to anatomical scans (a part of preproc-sess routine in version 5)
before measuring the contrasts. But for one of our studies, a reviewer has
asked if a “non-rigid image registration” would change results when we are
assessing activity within artifact-prone brain areas (e.g. anterior
temporal areas).
As far as I know, freesurfer registration works fine and even in this
study, we have found very strong activity/contrast within anterior tempotal
lobe. But I was wondering whether you have tested this possibility or not.
If yes, then I appreciate if you can introduce me a reference (published
article) to support our answer.
Regards
