Not alive, but not dead: disembodied human brains used for drug testing

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?

From the article:

> The brains are already almost devoid of the coordinated neural firing necessary even for minimal consciousness, says Brendan Parent, a bioethicist at New York University Langone Health and one of six ethicists on Bexorg’s advisory board. But the company also forestalls any electrical activity with the anesthetic propofol, among other measures.

I recognized that anesthetic from its famous irresponsible use-

"Attention to the risks of off-label use of propofol increased in August 2009, after the release of the Los Angeles County coroner's report that musician Michael Jackson was killed by a mixture of propofol and the benzodiazepine drugs lorazepam, midazolam, and diazepam on 25 June 2009." https://en.wikipedia.org/wiki/Propofol

Used properly, however:

"To induce general anesthesia, propofol is the drug used almost exclusively, having largely replaced sodium thiopental."

Honestly, there is so much terrible terrible terrible stuff going on in the world and happening to real people, I think it is safe to say that those brains are having a blast. Relatively speaking.

It just invokes a strong emotional response because it's so "abnormal", but if you think about it, there is so much more pain going on where no one bats an eye.

Perfectly avoidable pain even. So it's not even that aspect.

There’s no such thing as live dissection. It’s vivisection.

Well, we know how to make living brains insensate - that's who we all make it through surgery.

Presumably they're doing something similar - or using some other well-understood mechanism - to ensure that's not the case.

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.

That’s somewhat overstated.

We know anesthesia "works," and we know some of its molecular targets, but we do not fully know the mechanism by which it produces unconsciousness, ie whether anesthesia eliminates experience, or mainly blocks memory, report, and integrated neural processing.

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 done here is all about metabolism and structure rather than those much more subtle functions.

IMO the more questionable aspect of this entire operation is the use of "AI" to reach conclusions about how the test molecules are being metabolized, but that's a lot less compelling than implying that some company is somehow preserving life in a disembodied brain.

The word "alive" is doing a lot of work here. A brain is pretty much permanently fried after five to fifteen minutes without oxygen, and these are donor brains, not some emergency brain extraction team, so the timeframe will be much longer than that. There might be 'life' left in there in the technical sense, but there's no 'person' left.

“We are all aware that the senses can be deceived, the eyes fooled. But how can we be sure our senses are not being deceived at any particular time, or even all the time? Might I just be a brain in a tank somewhere, tricked all my life into believing in the events of this world by some insane computer? And does my life gain or lose meaning based on my reaction to such solipsism?”

NEW VISTA, OUTER RIM—Just a cycle ago, the brain was in a living person. Now, hours after its first owner died, it sits on a slab draped in tubes that quiver as they pump liters of blood substitute and other fluids through the organ, supplying oxygen and removing waste. As far as anyone knows, with many of its key functions intact but maybe awarness muffled by drugs, the brain hovers between life and death. As people subject it to experimental drugs, sensors record the brain's reactions, capturing hundreds of data points on its cells, proteins, and physiology. Then, after 24 hours in this state, it will be sliced into hundreds of pieces for more detailed study.

I just finished reading "That Hideous Strength" (CS Lewis) this weekend where they have a disembodied head kept "alive", and some convicts in the pipeline whose heads/brains, it is implied, will be experimented on similarly. Lewis was remarkably prophetic.

This is legal but I can't legally pay another adult for sex or take drugs that could harm me? And there are many restrictions on gambling. It's weird how some morals are legislated but not others.

"alive" is not a meaningful term. It makes sense only when you have blunt instruments to measure aliveness, like pulse, respiration, heart beat, etc.

Once you go much more granular, there's no particular spot to make a distinction between "alive" and "not alive", until you stop seeing any electrical, biochemical and mechanical activity of any kind, at which point you're basically saying "inert".

With what we are learning about how gut flora, can a brain be considered conscious while detached from the digestive system?

The obvious question I would have asked: given the concern that this may not be ethical if the brains are still “alive” AND the concern that a brain separated from the body probably doesn’t function these same, why wouldn’t we test things in living monkeys (instead of mice)???

It seems that the likelihood is high that the right animal model would yield superior data???

To be honest, if my only other option was to be buried, I would love to let my brain be connected to some machine that try to keep it as alive-like as possible.

Just please don't remove my brain before I'm 1000% certainly dead.

To some extent, volunteering for any sort of medical study is signing up to be tortured in the hopes that someone down the line might be saved by the research. Most cancer treatments, for instance, are objectively terrible to go through, and when you're testing and developing the protocols you're pumping already sick people full of poisons and hoping for the best.

There's some fraction of people who would prefer to be kept alive as a brain in a jar, depending on the alternatives, but getting to that point is going to require a bunch of people to volunteer to undergo excruciating torture as we learn how to keep the brain alive, how to keep them comfortable, how to keep them conscious, sane and let them interact with the world.

It looks like the families have to agree to do this, before your brain can be donated:
