think you can only do that by running some kind of rotating checkerboard
wedge during fMRI acquisition, and analyze phase reversals individually
in a flatmap (for example using caret) and segment according to that.
That is how most vision neuroscientists do it. To my knowledge there are
no clear anatomical boundaries for primary visual areas, you can only do
this functionally.
I do not see an accurate way to do this based on a template label.
But perhaps others with more experience can comment on that.
Cheers,
Bas
