<div dir="ltr"><div>I had not been aware of this 2016 breakthrough... I wonder if there was any brainwave activity?

"And just in February of 2016, there was a cryonics breakthrough when for
the first time, scientists vitrified a rabbit’s brain and showed that
once rewarmed, it was in <a href="https://www.rt.com/news/332074-cryonics-rabbit-brain-regenerated/" target="_blank">near-perfect condition</a>,
“with the cell membranes, synapses, and intracellular structures intact
… [It was] the first time a cryopreservation was provably able to
protect everything associated with learning and memory.” <br></div><div><br></div><div><a href="https://www.brainpreservation.org/large-mammal-announcement/">https://www.brainpreservation.org/large-mammal-announcement/</a></div><div><br></div><div>
"Using a combination of ultrafast glutaraldehyde fixation and very low
temperature storage, researchers have demonstrated for the first-time
ever a way to preserve a brain’s connectome (the 150 trillion synaptic
connections presumed to encode all of a person’s knowledge) for
centuries-long storage in a large mammal. This laboratory demonstration
clears the way to develop Aldehyde-Stabilized Cryopreservation into a
‘last resort’ medical option, one that would prevent the destruction of
the patient’s unique connectome, offering at least some hope for future
revival via mind uploading. You can view images and videos demonstrating
the quality of the preservation method for yourself at <a href="https://www.brainpreservation.org/aldehyde-stabilized-cryopreserved-pig-brain-evaluation-images/">the evaluation page</a>." <br></div><div><br></div><div>ASC in time may become a rival/alternative to vitrification. But due to its effects on our cells, it is supposedly good at preserving information, but not at maintaining viability for a future biological rejuvenation. And so it would be the ideal means of trying to achieve a high quality brain scan for a clone. As for myself, I view biological rejuvenation as an imperative, and a brain scan downloaded into a clone as a copy of me, but not the all important original.</div><div><br></div><div> I realize there are 2-3 potential threads contained within my post!
