Isn't cryonics about preserving dead people? Don't dead people have dead brains?
I don't know what to say.

Quote:Today brain tissue preserved with a modern vitrification solution shows virtually no freezing damage. Whole neurons are visible with intact membranes and well defined structure. This is the excellent brain preservation which Alcor can now achieve in human patients. Most "experts" who complain about damage caused by cryonics procedures are unaware that such preservation is now possible.
Same website:
The basic structural and chemical integrity of a brain in the first minutes and even hours after cardiac death is surprisingly good. It’s the restoration of warm blood circulation to an injured brain that is ultimately deadly, and that results in destruction that even future technology could not easily reverse (brain death). This is why the prognosis of patients declared “brain dead” while on life support is poor even for cryonics. Most candidates for cryonics suffer cardiac death, which is more amenable to future medical repair than brain death as currently defined.
So I guess they are saying it probably won't work for someone who is brain dead, but we will be happy to take your money anyway.
