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

Reminds me of a study I read once on binaural beats[0], that found the effect disappeared when they used pneumatic (non-magnetic) headphones.

[0]the theory that playing a different tone in each ear, that when superpositioned by the brain to produce a low frequency, would entrain the brainwave frequency to the modulated frequency.

If this were true wouldn’t fMRI machines cause either loss of consciousness or extreme hallucinations?

If a camera can see your eyes, why can't you?

The whole article is making a category mistake.

Contrast this with trans-cranial magnetic stimulation and claims this can induce the feeling of religiosity in people: you may believe in god, because your ferromagnetic particles align to believe in god in the right magnetic field..

(not really.. but still. the thing about induced states of mind by TCMS is true)

This feels just north of conspiracy theory logic. It's proven that humans can just barely sense large-scale magnetic fields, so how about if they can also sense extremely finely detailed fields in a way that solves long-standing philosophical and medical problems? Here are some supporting coincidences that have any number of alternate explanations, but it would sure be cool if this whole tower of conjecture was true, right? If you've seen conspiracy-theory debunks, the resemblance is rather strong.

> The result: some of those people showed a response to the magnetic fields on the EEG!

I wonder if that correlates with people who believe in astrology.

The brain could be using the weak magnetic field to glean info on what the brain is thinking...or you know, the brain could use the fact that its electrically connected to...the brain.

Hmm this leads me to recall a bunch of ancient pseudoscientific sounding beliefs and see whether or not they might be plausibly explained by this mechanism:

* Is it possible for humans to get a vague impression of other humans' thoughts via this mechanism? Not via body language, but "telepathy" (it'd obviously only work over very short ranges). If it is possible, maybe it is what some people supposedly feel as "auras"

* Some animals have a preference for sleeping direction in alignment with magnetic pole, are some sleeping directions "healthier" than others for humans?

That aside, I didn't follow the part about how this is an answer to the hard problem of consciousness. Why couldn't the brain achieve global summarization via another mechanism, and why does having this "global summarization" result in qualia?

I don't want to be mean but this honestly reads like an AI-fueled delusion.

I feel like the title should read: "If an Meta AI model can read a brain-wide signal, why couldn't the brain?"

"Wouldn't" suggests that the brain is choosing not to. I'm not sure this is the case here.

whenever I remind about mind reading - I get down voted and called schizophrenic. it's worse - tech is being actively used to sway large groups of population

This reminds me of the study about dog poop being aligned to magnetic north/south.[0]

It seems a bit silly, but I suspect that more of our life may be effected by biomagnetism than we yet realize.

Well how far do these fields propagate and do you need to read them from different directions to make sense of them? Think you’d want to answer those questions first. The sensors from the study are very close and all around the head. Also demonstrate there is some phenomenon to explain in the first place.

I’ve long thought it would be unsurprising if we eventually found evidence of certain kinds of telepathy. It would just be too damn useful, and tuning up one exquisitely complex magneto-electro-chemical instrument in close proximity to another similar one seems like a good way to at least get resonance. Who knows?
