Why do you remain alive after your eyes are plugged out regardless of the fact that the eye is part of your brain?

Because eyes are extremely useful but not vital. Even if you have a chunk of your brain removed it is still possible to survive. Usually if the brain stem is intact you can survive. Also, I am not a doctor but I think your eyes are attached to your brain and not actually a part of your brain. Otherwise everything on your head would be a part of your brain.
