Dear Emily,

These boundaries are mostly geometric and based on the atlas.

For the atlas building:

• the head/body boundary was place at the level of the uncal apex.
• For the body/tail boundary, I’ll defer to Jean Augustinack (CCed)

Cheers,

/Eugenio

What is the boundary FreeSurfer uses to distinguish between the hippocampal head and body? This may be for each subfield. In any case, if you could let me know the boundary, that would be great.

Thanks,

Emily
