Is cryonics (wrongly call cryogenics) quantifiable?
Answers: Cryonics is the low-temperature preservation of humans and other animals that can no longer be sustained by contemporary medicine until resuscitation may be possible within the future. Human cryopreservation is not currently reversible. In the United States, cryonics can individual be legally perform on humans after pronounced legally departed. The rationale for cryonics is that the process may be reversible in the adjectives if performed soon adequate, and that cryopreserved people are not late by the modern information-theoretic definition of death.
The interior premise of cryonics is that memory, personality, and identity are stored within the structure and chemistry of the brain. While this view is widely standard in prescription, and brain activity is specified to stop and later resume lower than certain conditions, it is not collectively accepted that current methods preserve the brain economically enough to licence revival in the adjectives. Cryonics advocates point to studies showing that glorious concentrations of cryoprotectant circulated through the brain before cooling can largely prevent freezing injury, preserving the fine cell structures of the brain surrounded by which memory and identity presumably reside.
To its detractors, the justification for the actual practice of cryonics is amorphous, given present limitations of preservation technology. Currently cells, tissues, blood vessel, and some small animal organs can be reversibly cryopreserved. Some frogs can survive for a few months in a in part frozen state a few degrees below freezing, but this is not true cryopreservation. Cryonics advocate counter that demonstrably reversible preservation is not necessary to bring about the present-day goal of cryonics, which is preservation of simple brain information that encodes memory and personal identity. Preservation of this information is said to be sufficient to prevent information estimated death until adjectives repairs might be possible.
I guess you could still say that this is experimental, but I really can't see preserved corpses being revived. I tight, if we could do that, surely we could revive preserved egyptian pharoahs. Not going to happen, but still a science.
