is the mind an extension of the body, or the body extension of the brain?


can brain function and exist without the body. will future technology enable this to happen

By gradually outsourcing the brain's functions to neuroprosthetics you can preserve you ego, your sense of self, but if you do it too fast you'll have an identity crisis, you'll feel like an imposter to your own identity.

I better question is what happens to a brain or mind without a body. So many biases and perspectives would change.

Sending chemical signals? yeah. Can it be preserved? to an extent Consciousness? Completely unsure.

I think a lot of people miss the practicality of things. Why would we have a brain exist without it's body? Consider the computational model in computers: You have input and output devices. If there is no input, there is no output. The brain is a computer that computes information that is inputted to it. A cold zephyr brushes against the skin of the hand, your hands are temperature sensors, this is sent to the brain and it processes this temperature differential, it then responds by increasing blood flow to the area to maintain optimum temperature.

A brain, as far as we know, cannot operate without receptors. Receptors wait for chemical signals to be sent in order to take action. Can you imagine a world outside of your senses? You cannot. A brain can still be preserved, but consciousness is a product of processing sensory informaiton, that's for sure.

So much effort into preserving a brain with consciousness intact, yet what would be the purpose of such a feat other than self-preservation for a business tycoon? Really, there is no one that important from a utilitarian standpoint, no super brain we'll encounter. The only vector for this would be economical. Given the Insane complexity of the brain, I don't think we'll do this until well into the distant future. Compared to physics, chemistry and computer science, which are quite logical with the exception of quantum mechanics, understanding how billions, even quintillions of neurons operate to form a memory, consciousness and such is just the craziest thing ever. If someone discovers how, we've essentially accessed the source code of reality for life forms.

This is like super sci-fi.

It would make a great story, someone required to be given emergency neuroprosthetics as their brain begins to succumb some sort of degenerative disease. It would be a lot like Alzheimer's (indeed that could be the disease) except they're only losing memory, they can still think, still learn, forgetting everything they once knew but still conscious through the entire process. Living through experiencing death, what a trip.

It could go either way they might decide they're a new person, perhaps even the child of the person who came before in some odd way, or they might decide they're still the same person but feel uncertain about it. What might even more interesting is if they end up with two egos, the new neuroprosthetic ego and a impression of the original that manged to make it into the other's subconscious, imagine being haunted by the ghost of your past self from within your own mind.

@Rebis is right, why would we have a brain without a body? They’re not mutually exclusive.

Separating out bodies from our consciousness created the concept of the “soul.” We have such an acute sense of our own autonomy that we convince of ourselves as autonomous from our own bodies. Taking a purely biological approach, our brains/nervous systems will stop working as soon as we don’t use them. Across species, the neurvous system changes as we age. For sea creatures, the little brains they have fuse into heir tissues (barnacles, male angler fish, etc), and for humans, our capacity for learning/processing diminished. Many of us get Alzheimer’s or another form of dimentia, then die when we can no long remember to breathe.

Not to mention our congnitive functions are dependent upon our diets. The brain is constantly reacting to our body and environment. I’d imagine it’s be quite traumatic for anyone to one day realize they were just a free floating brain...not that they’d have any proof, because their eyes, ears, and sense of touch would be gone, and therefore that whole processing center..but you could put them in a simulation and make the, think they were living a life! (But hooking up the brains, and stimulating certain parts that correspond with whatever you want the brain to think /perceive).

Brain translppants, on the other hand...

I’m suprised no one has mentioned the condition where your body doesn’t reginize a limb as it’s own, and you feel the need to amputate it. It’s very strange, and all patients are much happier once the limb is gone.

@Cognisant
If this weren’t an INTP forum, I’d tell you to delete that and start writing. It’s a quite brilliant premise.

I think that's a combination of phantom limbs and rejection of foreign body parts. The brain is immune to this to a degree, When someone has their arm amputated their nervous system is still sending signals to the part of the body that's missing so we still feel the pain. A brain is connected to the nervous system through the brain stem, linked through the spine, the brain itself wouldn't feel pain from being poked so that's not an issue.

Out of all organs, surprisingly the brain isn't actually rejected by a body. Pretty interesting, though no one has an idea how this would work for consciousness. A brain connected to a body of different lengths like the arms, different sensory feedback and so on. So I imagine the person who had a brain transplant (If a person can have a brain transplant, and it's not the foreign brain that has a body transplant) that it would feel very strange indeed.
