Hemispherectomy?

[Brian37]

If brain is a transceiver and consciousness is located somewhere else then consciousness can survive decapitation and it doesn't matter what happens with body.

Why aren't you conscious when you have anesthetic and are put under for an operation?

Did you see new colors or hear new sounds?

As I said, my subjective experience of the sounds I was hearing was vastly different. Unlike anything I experienced when not on drugs.

I am sure that if I ever took LSD though then I would see new colours, such as these guys are reporting

There is a huge difference between consciousness and cognition. If your doped up, or in an alcoholic black out, or put under for surgery it is simply a matter of being unaware in the same state as if you were fully lucid, healthy and have waking cognition.

But again, altering brain chemistry isn't the same as having your brain completely die with no function beyond any window. Nobody survives complete total and irreversible brain death. Once enough of your cells die beyond repair there is no more you.

The idea of being separate than one's body is simply old mythology, claims in all of antiquity because humans worldwide back then didn't have benefit of modern understanding of biology, or neurology.
