Dear all,
I am training a little on the IXI-T1 dataset for VBM. I studied the influence of age on GM density, following the principles of VBM with DARTEL by J. Ashburner (www.fil.ion.ucl.ac.uk/~john/misc/VBMclass10.pdf).
When I look to voxels where GM density increases with age, I got a strange result: many cortical areas emerged as having their GM density increasing with age (I expected no brain regions to pop up).
I find this very intriguing. Do you think I have made an error ? Or is it plausible ?
Thanks !
