Dear freesurfer users,
I am a new user of Freesurfer. I have a question about the parcellation: in my data, I am checking the pial and white surfaces of brains. I have observed on my subjects that surfaces are crossing in the hippocampus. I don't understand why the pial and white matter surfaces cross in that region! Is it normal? Is it use for calculating thickness? Is their a mean to fix that problem?
Thanks for your help, Charlotte
Hi Charlotte, Please read the answer to question 5.1 on the FAQ page for info about surfaces in the medial temporal lobe.
