Personality exists in the brain.
So if one was to remove the brain from the body there would still be a mind. So lets say science fictionally speaking. We were able to remove the brain and lets say the spinal cord and all the nerves and hook this up to a machine which could receive input. It could be said that a human consciousness resides in this bio-mechanical entity. It would have past memories, experiences of a human.
My question is would that person have the same emotions he had with a human body? I wonder with out glands that produce hormones in separate organs would consciousness change? Could it be that because the brain no longer has to manage a complex organic machine, it could devote all its recourse to the cerebral cortex and thus become super intellectual? Like the best CPU in the world? or would it be like how Joe Rogan describes being in an isolation tank? That we would have a psychedelic trip?
Would that person experience emotions differently? Or could this person still feel love? hate lust? How would this brain entity define itself man or woman? having no gender, no body would biological impulses change? Is a human a human without its human body?
I have a notion that we associate emotions to with a physiological change in our bodies as well. Could someone feel love with out that pang in their stomach? The fluttering of their hearts? Or anger without the constriction of facial muscles? Stress without shoulder muscle tension? Arousal without an erection? Sex has no more meaning. It it like being a eunuch?
I guess this all ties into futurists who say that sooner or later there will be a bio-technological integration and humans might gain immortality by downloading their consciousness into a computer.
At what cost I wonder.
