I'm not sure I understand what you are asking about. Do you mean in the
aseg.mgz or the aparc+aseg.mgz? Unknown is usually just stuff outside of
the head, but sometimes can be in the head (eg, with aparc+aseg.mgz).

Dear fellow colleagues,
in my study I use volumetric source spaces. In the process of creating
them, I decided to identify all available volumelabels FreeSurfer
"recognized" in the given mri image.
Every single subject inherits, despite all other volumelabels, a
volumelabel called "Unknown".
