Information-theoretic death

In cryonics, an information-theoretic death means a permanent death, a situation where the brain structures have become so disrupted that it is theoretically impossible to recover the memory of a person or a non-human animal. Therefore, no present or future medical achievement can revive such a person or a non-human animal.

Information-theoretic death can be caused by, for example, by the autopsy of brain, cremation or burial.
