Although there is much speculation, the real function of these neural oscillations is still unknown and I do wonder.
No doubt their true function will one day be discovered and just maybe someone will get a Nobel prize for nailing and proving that function.
I also wonder exactly what might go wrong if those oscillations where disrupted so that they were replaced with 'smooth and continuous' neural activity? -would there cease to be any consciousness or mind? or would it have only some miner effect because those oscillations have only some function of miner importance?

So if they used a pulse width of say 50 milliseconds at 1000 hertz, that would represent 20 complete cycles of that frequency which the ear would probably hear as a click but they can make that amplitude lower or higher and see where you can't hear it any more.

"In your book The Emperor’s New Mind, you posited that consciousness emerges from quantum physical actions within the cells of the brain. Two decades later, do you stand by that?
In my view the conscious brain does not act according to classical physics. It doesn’t even act according to conventional quantum mechanics. It acts according to a theory we don’t yet have. This is being a bit big-headed, but I think it’s a little bit like William Harvey’s discovery of the circulation of blood. He worked out that it had to circulate, but the veins and arteries just peter out, so how could the blood get through from one to the other? And he said, “Well, it must be tiny little tubes there, and we can’t see them, but they must be there.” Nobody believed it for some time. So I’m still hoping to find something like that—some structure that preserves coherence, because I believe it ought to be there."

1, as far as I am aware, Roger Penrose never said or believed quantum physics is wrong. I suspect that claim is just made up nonsense.
2, regardless of his theory, there is NO evidence or reason to believe that 'consciousness' requires some kind of fundamentally new physics of the world that in same way contradicts what we know about quantum physics.
Quantum physics, not to be confused with the Neil Bohr metaphysical interpretation of it which may well be wrong, is a proven scientific fact by an overwhelming mountain of evidence and, to date, there isn't a shred of evidence implying it may be wrong.

If we had to, like with some kind of artificial neuron circuit based on tubes in some kind of Manhattan project level exercise, could make neuron circuits, even if the thing was a mile long to do it. There is nothing fundamenal preventing tubes from doing the job of transistors and IC's in modern neuron circuits.

The error bars seem huge compared to the actual differences between peaks and valleys of the strobes.
If real, it is likely that, as the authors suggest, the sinusoids represent alternative sampling of left-ear vs right-ear stimuli in the brain. This would make sense given that if you sum the right ear + left ear data it is a straight line.

"My own view is that quantum mechanics is not exactly right, and I think there’s a lot of evidence for that. It’s just not direct experimental evidence within the scope of current experiments."
Not exactly right is not the same as wrong. Could be interpreted as partly wrong, but not completely.
String theory has no experimental support. Until that changes we will never know.
If you think you are smarter than Penrose just say so. Ironically, his credentials are far greater than your own, something you like to point out to others far too often. Try resisting that urge in the future.

I don't recall having an opinion you disagree with on this thread.
perhaps you are so stupid as not to comprehend your own posts.
"If you think you are smarter than Penrose just say so."

Majority of scientists means nothing by the way. They have to be climate scientists for it to be relevant. Since no poll has been done of only climate scientists that does not omit most of them, you have no proof I am wrong.
