Yes this is fascinating. I ran an expt recently to test whether it’s SaO2 or PaCO2. Still analyzing. It won’t fully differentiate unless it’s entirely SaO2, but could be interesting new method anyway. Will keep you posted! Thx!

What do you consider "reasonable"?
-
1. Have they attempted some sort of mitigation of respiratory effects? (Cardiac is harder, but also generally higher frequencies than interpreted by FC.) 2. On interpretation, have they left open the possibility their results are still driven by non-neural effects?

Or maybe look at what rsfMRI is actually being used for.. I could be wrong, but it seems to me that segmentation/decomposition based approaches are proving more robust than the classic graph theoretical/network analysis that are currently blighted with poor retest reliability...
-
Neither robustness nor retest reliability rely specifically on a neurovascular mechanism, and so it remains between possible & probable that many FC results are driven by physiological "noise." The question is, which?

Uhh doesn’t ICA just like, take care of this for me

If you can figure out what all the components represent, and if they are truly independent, then..... maybe!
