Hello FreeSurfer Team , 

I was wondering if you could explain to me what the “Left-Hippocampus” and “Right-Hippocampus” labels in the subfield segmentation are? Are they the tail of the hippocampi? Or everything that is not assigned to one of the other seven labels? 

Additionally I am wondering how the hippocampal subfields are ordered in terms of their determination? Is it a particular order or is it randomized?
