this is going to be the first of a series. are there any other pressing issues you need putting to bed?

I don't think neurology has anything useful to tell us yet unless chunks of your brain tissue are missing or something. What does neurology have to tell us about the experience of color, except that blood is moving around the brain? Who cares.

Geared up to distinguish phenomenology from neurological imaging eg MRI’s, realised Gus is lazy/dismissive and thought what‘s the point - a lad who doesn’t believe in archetypes while drawing a Tarot every day

What can an MRI tell a person with normal functioning brain what does it teach us that we care about

I'm not closed to the idea but MRIs have generally been grounds for what I'd call pseudo knowledge of the brain "oh cool this hemisphere has more blood flowing wow we really understand the mind now!"

I think it just tracks iron atoms in hemoglobin as red blood cells cycle through the brain, I think in order to provide oxygen for neurons. So you can see maybe levels of oxygenation of certain areas of the brain, which might mean higher levels of some kind of activity. In any case, it doesn't strike me as pseudoscience, unless you are really stretching the data to make far fetched claims.

Yes exactly it doesnt tell us anything. Medieval instrument

Used for associating regions of brain activity with certain categories of stimuli, I think. Similar to EEG to that end, but I don't know if electrical activity aligns meaningfully with oxygenation activity, assuming my understanding of MRI is correct in the first place.

Did you see that New Yorker article I mentioned, that used fMRI (don't know difference between MRI/fMRI) scans to locate words/concepts in the "idea space" of the brain? Very interesting, and much of it seemed conclusive enough to be spared the label of pseudoscience, if even not comprehensive.

Oxygenation might have something to do with metabolic activity, which might indicate that more active neurons need more frequent oxygenation, but I don't know. I'd like to know, though.

And if oxygenation is involved in neural metabolism, I'd presume that electrical activity is correlated with oxygenation, as I'd imagine the ion gates opening and closing requires an expenditure of energy on behalf of the neuron. If that is the case, I couldn't tell you what MRIs/fMRIs could tell you that EEGs couldn't, although I'm sure there is a meaningful difference between the two, seeing how expensive this equipment is.

Did you know the only known cure for autism in children is having Jane Austen novels read to them each night before bed

This stuff is just incredibly speculative as far as I understand. We have no idea how the brain is structured or how concepts are stored we don't even know if we are theorizing at the right level of abstraction
