I would assume that all sorts of proteins would clear out of the brain in cases of prolonged oxygen depletion.

I can't find it at the moment (edit: found it [2]), but I am sure I read something about Jerome Lettvin [1] doing some experimenting with CO2 but for something like schizophrenia, and that despite having good results he had to stop due to legal liability reasons or the like. I think it came up in an interview with him which I read a transcript of. [1] https://en.wikipedia.org/wiki/Jerome_Lettvin [2] https://www.mindstrengthbalance.com/learn/interviews/jeromel... (search for Laszlo to find the bit where they start talking about this)

“Carbogen” has an interesting history. https://en.wikipedia.org/wiki/Carbogen It has some sort of mind altering effect, and in the early days of psychedelic psychotherapy it was used to determine whether someone would freak out under the influence of mind altering substances. https://www.erowid.org/chemicals/carbogen/carbogen.shtml
