Dear all,
Please may I have this consulted:
I used SPM8 (two sample t-test) to generate the CON images and T-map images
from a single subject scans, before and after injection. While visualizing
the results we found many activation spots to be on the voxels outside the
brain.
While looking into the results the T-map images generated appear to have an
extra boundary layer (3 voxels) when compared with the CON images. {please
refer attachment}We presume, this extra 3 voxel boundary layer contributes
to the activations outside the brain in our results?
While these CON images from individual subjects are taken to the second
level analysis to look for group effects, the complication persists and
increases.
Can you please shed some guide light on this..
Many thanks for your time,
