Re: [Freesurfer] Fwd: V1 and V2 labels valid with clinical populations?

Hi Krista

I'm not sure we can. Certainly there are studies showing that in congenitally blind populations V1 can get recruited for other things

Just wanted to pose this question again to the Freesurfer community: Can anyone provide any advice on how to justify using the V1, V2 labels in FreeSurfer in clinical populations without also collecting functional retinotopy data?

Thanks! Krista

OK thanks. I see a lot of pubs using these labels. Can anyone provide any advice on how to justify using these labels in clinical populations without also collecting functional retinotopy data?

  I don't think we have any idea. The labels are based purely on anatomy, but
  whether those areas keep their functional specification we have no idea.

  let us know if you find out though!
