I would like to check something. I naively imagine* that if you freeze a person cryonics-style, no damage is done to their brain immediately. So that if you froze a person that was alive, and then un-thawed them 5 minutes after you froze them, they’d wake up virtually the same—alive and unharmed. Is this true?
*This idea is based on stories about children frozen in lakes and optimism.
“Children frozen in lakes” are not frozen, only hypothermic. If you actually get ice in your brain cells you die.
“Freezing” a person “cryonics-style” begins with drainging all the blood from their head, and the process takes more than a few minutes. So it is pretty much guaranteed to cause severe brain damage or death if you do it to a live person. Which means that it would not be legal, even if somebody had done that experiment they could not publish it.
I don’t think so. Vitrification and the chemicals used are poisonous, but fixing the toxic damage is presumed to be one of the easier steps in reviving someone’s vitrified brain.
This might be true for some definition of freezing a person but not with the protocols currently used by Alcor and CI.
