Apparently MJ was taking propofol to sleep, which another commenter said was akin to "getting a haircut by undergoing chemo".

Between what he did to children, and what his parents did to him, it's hard to really blame the guy for having extreme sleep problems though.

Here's a podcast deep diving into what it was he did.

Live dissection and experimentation on “alive but drugged” human brains is mental. How do you ensure that you aren’t torturing a brain that can’t see, hear or scream? How are you held accountable?

It's still an open debate whether the seat of consciousness (or even simpler, perception) is the brain. see e.g. Wahbeh, H., Radin, D., Cannard, C., & Delorme, A. (2022). What if consciousness is not an emergent property of the brain? Observational and empirical challenges to materialistic models.

Ok, I only skimmed the paper but it seems like all of the "non-local phenomena" in support of their theory are basically psychic powers. Not exactly strong evidence.

I will be removing my organ donor status. This is horrifying.

It looks like the families have to agree to do this, before your brain can be donated: > Bexorg obtains brains in partnership with organizations that procure donated organs for transplantation, and Vrselja says once families understand the company’s process and goals, their response is overwhelmingly positive.

Can't the donor stipulate take anything but the brain?

oh, look, seems like we found the guy who can define what consciousness is! and not just that ... he even knows the lower boundary of it, too.

I think there is worlds between definitely defining what consciousness is, and what are some of the scenarios and conditions under which consciousness cannot ever happen. And on top of that, they put a sedative, just in case.

my comment was meant a little bit humorous.

> I think it is safe to say that those brains are having a blast

How could you possibly say that? You are positing that the brains are both conscious and happy. Both of those are leaps.

> It just invokes a strong emotional response because it's so "abnormal"

You are making an assumption about why people find this horrifying, and the assumption you made was uncharitable.

> OTOH, this is HN, I guess. Having empathy for real people would be harmful to the business model of most people's employers.

I do not see how people on HN being horrified by human brain experiments means they do not have empathy.

It's not a great article, and it glosses over the reality that if you hooked this brain up to an EEG it would show unequivocal brain death. CELLS of the brain are alive, but in terms of being able to function in any sort of coordinated way there that ship sailed minutes after the person who donated their organs died. The wave of depolarization that marks brain death isn't something we can reverse, and what's being do…

Everyone upvote this guy more, thanks

When I had my ear surgery about 20 years ago, the doctor explained to me that I would be awake for part of the procedure, but the anesthesia meant that I would have no memory of it.¹ It’s a weird thing to think about whether that lack of memory would obviate the pain or discomfort of the moment. ⸻ 1. As it turned out, I was so frightened in the lead-up to the surgery that they had to do general anesthesia on me becau…

> so I was unconscious for the whole thing

Or so they claim - the patient would have no memory of that anyway.

You're free to stop there. We can also turn it around, and I can ask you for any paper that details the theory of why the brain should be the location of consciousness.

I only gave one example and Wikipedia to start with. There's a lot of material out there if you're (rightfully) skeptical of that one paper. I don't even know what you're refering to as "their theory", as the way I read it, they're basically documenting various co-existing theories, and the authors don't disclose which one they find the most likely. I also don't see it as necessary for science to pick one; it's all about theories. I prefer documentation of all possible theories, and see no reason to dismiss one over the other unless they're disproven. I pointed to that paper, because any paper that talks about alternative theories shows the point I was making: We don't know yet. The point was not to claim that they've managed to put together good or bad arguments.
