It makes sense they wouldn't look at it, there are very few, if any, well-validated clinical uses for it. However, they might have taken it as a baseline for later comparison, and it is definitely plausible when surgery is involved that visible abnormalities could be seen in fMRI that might not show up in MRI, either now or later.

I don't think there would be much clear guidance for them on how to interpret any such fMRI abnormality on its own, but it might still be something useful for further investigations, and this might especially be the case for surgery. It might also have been done as part of research, if you consented to anything like that?

I am NOT an expert on fMRI in medical contexts, but you can surely get a rough idea of the potential value of fMRI with a quick search: https://scholar.google.ca/scholar?q=fMRI+surgery+brain&hl=en...

I raise this as given the extent of research performed on my brain, the fMRI was not discussed with me whatsoever, nor was it mentioned in the pre-operative justifying factors. I raise this in relation to this submission; I hadn't given it any thought before.

Thanks for the link, useful to read.
