The length of the blue segment—preservation quality—is affected by three things:
蓝条长度(储存质量)由三个因素影响:
1) How much damage happened before you legally died. How old were you when you died? How much had your brain deteriorated by that point? Did you suffer from a dementia-causing disease like Alzheimer’s and how much permanent damage did that disease do?Did the thing that killed you damage your brain (like brain cancer, or a head injury) or was your brain unharmed?
法定死前所受损伤。损伤影响包括死时年龄、死后大脑恶化程度、有没有如老年痴呆症的失智症引起的疾病和永久性损伤、使你死亡的比如脑瘤和颅脑损伤是否破坏了你的大脑或者大脑完好无损。
2) How much damage happened between when you legally died and when the cryonics team started working on you. In the ideal situation, your heart stops and before any changes happen in your brain, you’re stabilized and put on ice. Often, this isn’t how things go, and every unattended minute that passes after legal death has a big impact on the brain and shortens the length of the blue segment. But cryonicists believe that true info death doesn’t happen for many hours, or even days, after legal death occurs, and that there’s often hope in cryopreserving even people who lay “dead” for a while before being found.
死亡到冷冻的损伤。理想情况是心脏停跳之后,在大脑没什么变化前稳定冻成冰棍。通常大脑怎么样变化不重要,法定死后每耽搁一分钟都会对大脑有很大的影响并缩短蓝条。但是冷冻专家相信真正的信息死亡在法定死后不会持续几小时几天,死了好多天才被发现再冷冻上也有复活的希望。
3) How much damage happened during the vitrifying process. Vitrification itself—at least the way it is currently done—causes its own damage to the brain. Cryonics research focuses mostly on mitigating this factor, and it’s dramatically improved since the earliest days in the 1970s—the series of images at the bottom of this page shows the progress that has been made.
玻璃化过程中的损伤。玻璃化本身也会对大脑造成损伤。冷冻研究更关注从影响因素上想办法,自从1970年后有了很大的进步。本文最后会给出冷冻的发展过程图。 |
