如何判断自己生死？人体“输入设备离线”后

失去了所有感官功能，怎么知道自己是死是活？

假设我经历了一场车祸，昏迷了，等到恢复意识，我发现已经没有任何感觉，我处于一片难以形容的黑暗之中，没有视觉听觉嗅觉味觉触觉，感觉不到身体，无法与外界沟通，但我是苏醒的，可以思考。

那么我该如何判断：

1.我的大脑还正常存活，只是因为神经受损失去所有身体感觉能力；

2.还是我的大脑已经死亡，我的“意识”凭借某种其他载体存在着？

不知道是否有类似的假设，或者可以从生物学、神经科学、哲学层面直接驳倒这种假设？如果假设成立，岂不是植物人安乐死就成了谋杀？或者我们如何得知死后不会有这种“意识游离”的状态？

合理的推断建立在事实上

sensory和consciousness有关联，但是失去sensory不代表就没有意识，也不代表不能观测到conscious state。打个很不恰当的比方，一台电脑你把键盘鼠标显示器拔了，但是操作系统还可以运行。而且大脑不会因为断开了感觉输入就瘫痪，因为没有感觉本身也是一种『感觉』，高级功能包括意识是肯定具有这样的元功能的。

可以想象一下，因眼-口鼻-耳-躯干的方位是不尽相同的，传入大脑的通路也是不太一样的。粗略的把感觉及传导通路说一下：

视觉：视束=>视交叉=>外侧膝状体=>视皮层

嗅觉：经嗅球=>嗅皮层

听觉：耳蜗=>腹/背蜗神经核=>随丘系上行（blahblah一大堆....）

前庭觉：耳蜗=>前庭核=>皮层和小脑

躯体感觉：好吧又可以分nn种感觉（痛温触等等）。总之脖子以下部位，已经在延髓汇总成了两条纤维先过脑干，然后再过丘脑，再去感觉皮层。而头部先要在脑干的核团（三叉核之类的）中转一下。

本体感觉：在脊髓就完成了反射，也和躯体感觉一起上行到皮层和小脑

味觉：三叉神经=>脑桥=>丘脑等

解剖是比较晕人。1、2是比较独立的，3-7都要经过脑干（尽管在脑干的高度不尽相同）。一次性把所有的感觉系统切断是不太可能的。不过一些大范围损伤或者脑干严重损伤可以断开多个系统，产生很多不同的病情，比如：

植物状态：失去了意识，对外界几乎没有反应（对疼痛之类可能会有反应）。呼吸心跳自主维持，尚存日夜节律，基本生理内环境稳定。

脑死亡：不仅是意识失去并且无反应，整个大脑，从高级功能到低级功能都丧失，体温、呼吸、循环都不再能自主调节，在现代的生命支持系统下（呼吸机、循环辅助等），是真正的『活死人』

Lock-in：这种很有意思，乍一看像植物人，但是意识清醒，高级功能保留（皮层部分无损），感觉上行系统可能会有保留，躯干面部运动系统全挂，但是眼球可以动。因为保留了部分感觉，所以可以通过转眼来和外界交流。

回到开头所说，失去感觉不一定失去意识。除开病例，假象一个极端的例子：所有的感觉系统都断开了，但是脑干中维持觉醒状态的网状结构功能完全，我们得到了一个非常极端的病人，连眼球都不能运动，那我们能判定他是否死亡么？回过头来看脑死亡的诊断，其实非常苛刻：无自主呼吸循环，无脑干诱发电位，脑电波平直，无意识，瞳孔散大无对光反射等等。但是只要皮层活着，就肯定有脑电波，就肯定有脑干诱发电位，这种情况下医疗上是不可能判断其为死亡的。安乐死是伦理方面的问题这里不讨论了。

再额外讲一下植物状态，这个在医学上定义实际上是有一定模糊的，毕竟神经系统如此复杂，不可能每个病例损伤程度、功能保留程度都是一样的。比如上面举例失去绝大部分感觉，对外界完全无反应，意识状态波动，这样的病人算什么呢？这里又要感谢科学的进步了，虽然无法通过运动来表达，但是大脑『思维的痕迹』是可以用MRI之类的Brain Scan获取到的，比如新英格兰这篇论文《Willful modulation of brain activity in disorders of consciousness》。
