Even in the Netherlands, where assisted dying has been legal and normalised for over 20 years, only about 6% of people die this way - and just one in nine cancer patients, the group it's most available to. The piece digs into why so fe

Connectomics — mapping every neural connection in a brain — is advancing fast enough that a complete human brain map may be feasible within a decade or two. But there's a problem nobody talks about: human brains donated to science are

A piece outlining how if the recent claims that Eon systems have uploaded a fly should count as valid, then it would already be the case that these previous papers had uploaded a fly as well: -Shiu et al, -Lappalainen et al., -the NeuroMech

...I'm not sure what this is supposed to mean. Asking about ideal conditions is a reasonable starting point for establishing a baseline, and high-quality preservation is definitely something that can be achieved under laboratory condit

These were physicians who were being paid to complete surveys - no reason to think they were more likely to select/reject this one over any of the others available to them at the time.

First author here to provide context: 1. We had both general practitioners and various specialists. We set a minimum quota for each so that we'd get some sense of what all the various groups thought. We aimed for and obtained 180 speci

Is Terminal Lucidity Real?(preservinghope.substack.com)

As a neuroscientist, I became fascinated by the supposed phenomenon of 'terminal lucidity', where people with severe dementia suddenly become lucid again shortly before death. It sounds impossible given how catastrophically damage

"The treatment works like this: doctors use a modified teleporter that targets just one cubic centimeter of brain tissue at a time. That tiny chunk gets scanned, disintegrated, and instantly rebuilt in the exact same spot - minus an

I don't think that's true at all. We routinely provide people with surgery by highly trained specialists and ongoing indefinite care while they're still biologically active. Outside of the US, this can even be done reasonably

This is akin to saying that because we don't know how to unify general relativity and quantum mechanics, that we know nothing about physics. One can admit there's still a lot left to learn about a field while acknowledging the fun

That's what's outlined in the article! (Btw, I (OP) am not the writer of this piece, I'm just quoting it. But I am also a neuroscientist who's interested in brain preservation, for what it's worth.)

The idea of cryopreservation is simple and beautiful: When a person is beyond saving by modern methods, we can give them another lifeline. First, perfuse their bloodstream with antifreeze. Once administered, it’s possible to safely cool the
