Dear Freesurfer specialists,
we are currently working on a comparison paper between manual segmentations and freesurfer segmentations of the hippocampus. In the paper by Jovicich and colleagues (2009) they mention that they generated their own segmentation atlas for the full brain freesurfer segmentation that consisted of different people of different age groups. We found this really interesting and wondered which segmentation atlas is used in the default stream of Freesurfer for subcortical segmentation? How many people were in that sample that created this atlas and which age were they? As we are specifically working with the hippocampus segmentations, it would also be very interesting to know what the mean size of their hippocampi was? Or is there maybe a paper that specifically describes in detail the descriptives of the used subjects for the standard atlas you could recommend us? Thank you very much for all your help and your time! Cheers, Johan and Elisabeth
