xAI had a lot of negotiating power here because Anthropic had ~0 comparable options and ultimately desperately needed the compute now. So, it wouldn't surprise me if data sharing was an explicit part of the agreement

Nothing to add to this conversation in particular, but just wanted to say - truly amazing paper. Well done!

Should have added one sooner! Here you go: https://1393.xyz/rss.xml

I appreciate that you feel this way, but the mechanisms behind exactly which neural circuits are activated by TMS are simply not yet fully understood.
From 2024:
> Transcranial magnetic stimulation (TMS) is a non-invasive, FDA-cleared treatment for neuropsychiatric disorders with broad potential for new applications, but the neural circuits that are engaged during TMS are still poorly understood.

Of course!
But also:
> Although the biology of why TMS works isn't completely understood, the stimulation appears to affect how the brain is working.

I think it's reasonable to assume there's room to sharpen our understanding of it quite a bit.

The whole argument hinges on the idea of tuned resonance: https://www.nature.com/articles/s41598-025-07988-2

If you're interested in my personal chain-of-thought on the subject:
This was where I started pulling this thread (October 2025): https://1393.xyz/writing/could-the-root-cause-of-alzheimers-...
And this is an even further ancestor of the ideas (December 2023): https://1393.xyz/writing/are-we-only-conscious-while-were-le...
I'm operating off of my own subjective experience, and this idea lines up tightly with System 1 and System 2 in cognitive psychology.
It seems that many jump to "AI psychosis" when one mentions magnetic fields, but the evolutionary tree is very straightforward:
1. Nature evolves magnetoreception for navigation
2. Eventually, a brain in nature with magnetoreception accidentally "hears" its own magnetic field with with resonance
3. That lossy global summary of the brains ends up being an evolutionarily advantageous "higher-order sense"
4. Evolution sharpens the blade for many years
On first principles, that seems perfectly viable and even likely given that magnetoreception was such a boon for survival for all life.
Just glad others are finding it interesting!

Not necessarily - I think it works like Daniel Kahneman's System 1 and System 2. Your conscious system is System 2 - when it's not working correctly, you just fall back to System 1.
Independently, since the whole idea relies on resonance, it may be the case that an fMRI doesn't actually interfere with the "stochastic resonance" mechanic quite like TMS (transcranial magnetic simulation) seems to.
If you model the brain this way, dementia looks like a clear breakdown of System 2, which is an interesting thought experiment even if the mechanics aren't perfect: https://1393.xyz/writing/alzheimers-is-the-symptom-not-the-p...

In cognitive psychology there's all sorts of evidence that we have two distinct processes, but I don't think anyone has really mapped it to a physical system yet.
Modeling two physical systems is pretty interesting though because dementia ends up looking like a clear failure of System 2. Really neat idea generator even if imperfect.
