Hi An Lijun
The choroid is a plexus of ependymal cells that produce CSF. it is pretty
tough to segment and mostly we include it to get more accurate segmenations
of the hippocampus where it is adjacent to ventricle and the ventricles
themselves. I'm not sure I've ever seen any normative stats on it though.

Dear Freesurfer experts,
I have a little question about the structure 'chorid-plexus', I am not very
deep in brain
anatomy and function. Could anyone have a sense of what is the normal range of
this
structure volume from Freesurfer reconall?
I found that mean of 'chorid-plexus' in ADNI is around 1500 mm^3, when I ran
reconall for my
local subejcts (a local dataset), I found the mean of 'chorid-plexus' is around
800 mm^3.
Could anyone give an explanation or a paper I could refer to for this
'chorid-plexus'
structure?
Thanks so much!
Best Regards,An Lijun
