If a Meta AI model can read a brain-wide signal, why wouldn't the brain?

For what it's worth, I have a disorder that causes me to see "auras" around people quite often. The nature of the disorder is that my brain can't filter out its own sensory noise properly, giving rise to a lot of visual artefacts that non-disordered brains filter out. These range from 'TV static' to stuff that's not a million miles away from diffusion model artefacts, but the auras around people I see pretty much all the time especially against plain backgrounds. It's not very well-known or studied but fMRI studies have recently implicated the same serotonin receptor psychedelics target, and it's also linked to migraine.

I think this disorder being more prevalent than expected would be a good explanation for auras. It was once thought to be very rare, but many people who have it aren't actually affected enough to seek out a diagnosis. It wouldn't be an unreasonable source for images like auras, saints' haloes, and other things like that since they're just an ordinary part of vision for me. I also think it somewhat vindicates Aldous Huxley's thoughts on the subject.

I really like the idea of electrical fields being somehow important for consciousness, and it's not something I'd rule out off the bat. I just think that disorders of perception are a better explanation for auras and similar phenomena.

It's tentatively proven that humans react to large magnetic fields. The reaction can come from simple interference, without ever being processed as a sense.

But there's so much more bullshit. That an MEG measurement was decoded only means that the brain produces a magnetic field that correlates with the information it is processing. So there's no Faraday cage in our head. Great. But the brain already knows what it is doing. All that information is there, very fast and reliable. Why should it try to decode its much less detailed and very weak magnetic field then? Where are the sensors? MEG needs super-conduction to work, and doesn't work when there's any disturbance. In the institute where I worked, it was forbidden to use carts (for moving equipment or coffee or whatever) on all floors in the corner where the MEG was located when there was an experiment going on, because it would disturb measurements. A few crystals aren't going to overcome those problems.

OMFG. There's really no point in reading this.
