Dear FreeSurfer list,
When I look at inflated surface of my subjects (healthy males and females), almost all of them have a concavity in the posterior part of the brain (the arrow in attached image). It doesn't look correct to me. What can cause this problem?
Thank you, Tanja.
When you look at the case in tkmedit, in that same area, do you see an error? Looking at your snapshot, it looks like it could be normal.

I agree, sometimes this happens in the inflated surface and I don't think it's cause for concern

Dear Bruce, Allison,
Thank you for your answer.
In tkmedit the surfaces look good. Can this concavity mean that sulci are deeper in this region as compared to neighboring regions? I am not sure I understand how to interpret the inflated surface, therefore I cannot control if it is correct.
Best wishes, Tanja.

no, I don't think it means that. It has more to do with the overall shape of the brain I believe, but we've never really investigated it On Sat, 30 Apr 2011, Tetiana Dadakova wrote:
