[Freesurfer] Ex vivo segmentations

Hi Bruce and Doug,

I have processed a few ex vivo brains with the help of the ex vivo freesurfer pipeline (outlined in https://surfer.nmr.mgh.harvard.edu/fswiki/ExvivoRecon), and have extracted their cortical thickness. So far the range of the cortical thicknesses have been approximately between 3.70-3.90 mm. Does that number sound reasonable for ex vivo brains? I am asking because the typical cortical thickness that I would expect to find on an in vivo brain would be between 2.05 - 2.35 mm.

Thanks in advance for any advice!

Best,

Panos
