Hi Hankee,
For the parahippocampal gyrus, I would do the following to correct for head size:
Raw Parahippocampal volume (as derived from aparc.stats)/ICV (as derived from aseg.stats)
Best,
rahul
hi, Now I use the parahippocampal gyrus gray matter volume to divide the total gray matter volume,after that I use the ratio to do the statistics. I think though this procedure can adjust the head size for individual subjects. Am I riht? or I can do like this way?
Bests hankee
