Thanks Bruce and Eugenio,
Suppose I had two identical images of a subject, but in one image I reduced the contrast of internal lamina while leaving the rest of the image intact...just removing internal intensity differences, but leaving the outer boundary contrast intact.
Would the images result in very different subfield segmentations?

Hi Josh
it depends on intensity differences if it can find them as well as boundary/geometry.
cheers Bruce

I'm trying to understand Leemput's subfield algorithm better as
implemented in Freesurfer. Does the algorithm make use of intensity differences in the internal hippocampal lamina from the subject's T1 image to warp meshes and assign subfield probabilities? Or does it depend only on outward boundaries of the hippocampus and probability priors to determine the inner boundaries between CAs and dentate gyrus?
