Bit of a sensationalist title - EEG/iEEG measurements have led to worthwhile clinical outcomes but also are an avenue for bunk pseudosccience so it pays to be careful whenever you see the words 'brain waves' paired with some large claim.
More accurate, much less sexy title: Intracranial Recordings Uncover Spiral and Concentric Brain Waves During Memory Tasks" (study completed only on small cohorts of epilepsy patients performing constrained memory tasks).
No inner workings revealed or laid bare, just another piece of evidence contributing to a small part of the debate in cortical electrophysiological studies on whether or not some data measures can be discarded as the downstream, messy noise of the neurons firing or actual, high-fidelity signals of activity
I wouldn't be so sure that the brain necessarily clocks faster than that. I think it's more likely that very fast chains of thought are defined by the flow of the wave rather than its frequency. Maybe that's also why it's possible to benefit so much with just a few seconds of extra consideration compared to an initial kneejerk reaction, etc.
Of course any science coming out that observes things that LLMs don't have is not going to find much excitement on HN. It would mean to face reality that LLMs are merely child toys compared to the real deal which is the human brain.
I think skepticism is healthy for the vast majority of sensationalized titles especially those coming from corporate entities. You'll very often find me in those OAI/Anthrop threads being very critical of their claims.
I like applying that same rigor to articles like this one. This is not a revolutionary discovery, it is a possible, un-replicated new avenue that could become revolutionary with enough of an evidence base. But there are many dozens of these same kinds of discoveries published all the time often leading to dead-ends (which is actually great since that's another rabbit hole you no longer have to chase - here's to null findings!)
In the same way you shouldn't accept PR regurgitated by so-called 'independent' journals when they come from corporate and government institutions, the same rigor should be applied to PR from universities seeking grants
It’d be interesting to try and model the various waveforms observed as time crystals and see if the mathematics of the latter can (partially) predict the former.
Brain waves are to biological neural populations what large-scale, low-dimensional activation modes in the transformer’s residual stream are to an LLM.
> Surprisingly Complex Waves Reveal the Brain's Inner Workings
From my ignorant point of view I can't quite make sense of the title. Brain is probably the last organ one would be surprised to find complexity in. I can see "surprisingly complex wave reveal spleen inner workings" being a good title, like "wow, we though it was a dumb blood filter, but look what we found!" kind of a thing. But for the brain isn't the default assumption that has it complexity we haven't figure out yet?
“The work coming out is moving this from ‘Are they relevant?’ to ‘This is a major motif of how the cortex processes information,’” said Earl K. Miller(opens a new tab), a cognitive neuroscientist at the Massachusetts Institute of Technology.
I suspect, if our conscious experience === the waves created by neuron's firing, that the hum of the GPU when running a LLM doesn't have the dynamic range to meaningfully talk about having a conscious experiences.

I thought AGI, um I mean "super intelligence", is just around the corner, so we have essentially already cracked it, just needs some fine tuning? /s

But that's armchair conjecturing.
