What makes my consciousness mine ?

In summary, the conversation discusses the concept of consciousness and whether it is tied to one's own identity. The topic of neuro-transplantation and its potential effects on consciousness is also explored. The conversation ends with a question about the purpose of the discussion.

Why would it not be yours? If it belonged to someone else, then it wouldn't be yours, would it?

EDIT: I'm not trying to be flippant. That's really all you can say about it. You are who you are during some time of existence and there's no point in asking why, at least from a scientific perspective. Your brain gives rise to your consciousness in ways that are not understood.

What do you mean by the question?
You (as can be identified) are a body and a mind, the latter being an emergent property of the former. You are your consciousness

Nick,

Not to make light of your question, do you feel like different people with different personalities (at different times), feel like you are disassociated from your body (at times), or, is this a purely academic exercise ? The response to this question will help.

If my left brain hemisphere would be switched with another guy's left brain hemisphere , and vice-versa, or maybe a smaller part of the brain not as big as a hemisphere, or maybe that transplant or transfer would be done neuron by neuron over a longer period of time, who's consciousness would end up being... who's ?

I would predict you'd have a real confused set of people until the foreign chunk of brain found a clique with the rest of the body, based on stimuli and internal genetic programs.

You can give someone a piece of your mind, but you can't give someone a piece of your brain, at least not yet. If and when that ever happens, I think it would be like a psychotic "symphony" with a very bad finale. Look at the US Congress. Can you imagine all of that going on inside one skull?

SW,

:yuck: :rofl:

Nick,

So, back to my original question. is this a purely academic exercise ? It is hard to pin down, since you answer each new question with a new one of your own.

Rhody... :confused:

Neuron by neuron is probably a very different proposition (but who really knows). You might even try to transplant neocortical column by neocortical column. Each neocortical column contains about 10,000 neurons. Apparently the only difference, or at least the main difference, between the mouse cortex and the human cortex is the number of neocortical columns. These are the structural units of the neocortex for all mammals. You can look up the Blue Brain Project where the mammalian neocortical column has been simulated on a supercomputer. My guess is (and that's all it is) that gradually replacing neocortical columns would not be perceived by the subject as affecting her/his consciousness. The neurophysiology that underlies consciousness is a feature of the entire cerebrum (including subcortical structures) acting as a system with stored bits of memory and 'programs' all over. These are pulled together and refreshed by complex signaling subsystems. So a single transplanted neocortical column might simply adapt to its environment and "blend in". In other words, it would become a part of the big symphony by playing its assigned role and not try to play its own tune.

Seems to be an adaptation of Theseus' ship. Neurones are arranged in networks which can change over time. I would imagine if you exchanged a chunk all sorts of weird things would happen but you wouldn't have two confused people (unless you took a whole hemisphere: see split-brain phenomenon). What you would get is two people who are subtly or radically different to the first two patients, drastic personality changes, odd tangled memories etc

Is this about neurogenesis or like the paradox of Theseus’ ship?

https://www.physicsforums.com/showthread.php?t=488045

In terms of the neurology, I wasn't talking about neurogenesis per se, but "neuro-transplantation" in response to the OPs question. The basic idea is that components of a system are constrained by the system in such a way that the system maintains its identity even as its components are replaced. This should be true even if all the components were eventually replaced (without significant disruption of the system's architecture) provided the components can satisfy the system's requirements.

In the neurological context, the question is whether the transplant can be made to operate to satisfy the system's requirements in its new environment. For the reasons I gave in my previous post, it might well be possible that a transplanted neocortical column could be modified by the system in such a way that the system's identity is maintained. Now just what is meant by a system's "identity" is a philosophical question best discussed in that forum. In the present context, the system preserves the continuity of the subject's consciousness without the subject noticing any change.

Nick,
When I asked,

is this a purely academic exercise ?

and you answered ,
Yes.

About a week ago, do you have any more to add to your inquiry ?
It has been about a week, and I assume you are satisfied, no ?

In his book, "The Emperor’s New Mind" (pg 27), Penrose asks a similar question. Penrose cites Hofstadter and Dennett from their book “The Mind’s Eye” which can be found online here:
http://themindi.blogspot.com/2007/02/introduction.html

An idea frequently discussed in this kind of context is the teleportation machine of science fiction. It is intended as a means of 'transportation' from, say, one planet to another, but whether it actually would be such, is what the discussion is all about. Instead of being physically transported by a spaceship the 'normal' way, the would-be traveler is scanned from head to toe, the accurate location and complete specification of every atom and every electron in his body being recorded in full detail. All this information is then beamed (at the speed of light), by an electromagnetic signal, to the distant planet of intended destination. There, the information is collected and used as the instructions to assemble a precise duplicate of the traveler, together with all his memories, his intentions, his hopes, and his deepest feelings. At least that is what is expected; for every detail of the state of his brain has been faithfully recorded, transmitted, and reconstructed. Assuming that the mechanism has worked, the original copy of the traveler can be ‘safely’ destroyed. Of course the question is: is this really a method of traveling from one place to another or is it merely the construction of a duplicate, together with the murder of the original? Would you be prepared to use this method of ‘travel’ – assuming that the method had been shown to be completely reliable, within its terms of reference? If teleportation is not traveling, then what is the difference in principal between it and just walking from one room into another? In the latter case, are not one’s atoms of one moment simply providing the information for the locations of the atoms of the next moment? We have seen, after all, that there is no significance in preserving the identity of any particular atom. The question of the identity of any particular atom is not even meaningful. Does not any moving pattern of atoms simply constitute a wave of information propagating from one place to another? Where is the essential difference between the propagation of waves which describes our traveler ambling in a commonplace way from one room to the other and that which takes place in the teleportation device?

Suppose it is true that teleportation does actually ‘work’, in the sense that the traveler’s own ‘awareness’ is actually reawakened in the copy of himself on the distant planet (assuming that this question has genuine meaning). What would happen if the original copy of the traveler were not destroyed, as the rules of this game demand? Would his ‘awareness’ be in two places at once? (Try to imagine your response to being told the following: ‘Oh dear, so the drug we gave you before placing you in the Teleporter has worn off prematurely has it? That is a little unfortunate, but no matter. Anyway, you will be pleased to hear that the other you – er, I mean the actual you, that is – has now arrived safely on Venus, so we can, er, dispose of you here – er, I mean of the redundant copy here. It will of course, be quite painless’) The situation has an air of paradox about it. Is there anything in the laws of physics which could render teleportation in principal impossible?
I think it makes sense to dismiss any definition of the concept of ‘me’ that we are so accustomed to. There is no 'me', there is no single thing or substance that the 'me' is dependent on - the 'me' is only a pattern, the material for which is replaced regularly by the body's own devices. DNA splits, and new cells are formed, while the material for the old cells is reprocessed or discarded. We can replace the concept of there being a me or you with the concept of there being a phenomenon (or set of phenomena) that occur and is dependant on the material on which it occurs. But the phenomenon is not anything more than that. It is analogous to a wave on the ocean, moving along the surface, and constituted by all sorts of different molecules over time, but the wave is not dependent on a single set of molecules and does not exist separately from the water. Other than the water, there are no substances, natural or supernatural, required to define the wave.

I remember one of Dennet's talks where he presented the factory view of consciousness and asked the question "what if nobody's running the wheelhouse?"

I think it's partially helpful for studying mechanistic questions, but we still need to consider the "phenomena" as you call it. As with the case with any phenomena, it's a boundary we define arbitrarily. We isolate some information structure (like a "wave") from the rest of the universe and give it a name ("me" or "I" in this case). Where we choose to set the boundaries is arbitrary in the case of a wave, and even in the case of "me" (some people might include their arms and legs part of their "me", some people may consider these just appendages of their "vessel"). But in both cases, the majority of the wave, the peak of the wave, the majority of the subjective experience is always included inside these boundaries. So while the boundary is fuzzy, by consensus reality, it's somehow consistently there. Consensus reality wouldn't be particularly important when studying a wave, but when it comes to asking questions about subjective experience it's more difficult to avoid the subjective perspective.

Anyway, it's still a big mystery as to why matter can have a subjective experience in the first place. Once (if) we figure that out, I'd hope a lot of these questions will become easier to answer.

An Interesting Counter to Dennet and Hofstadter's highly reductionist views would be that of David Chalmers (who in fact was a former Hofstadter student). For anyone reading too much of Dennet and Hofstadter (which is easy to do, because they're both quite good), The Conscious Mind might provide a good counter.

We can observe and describe consciousness in its global manifestations (just by talking to someone). I have no doubt that we can eventually understand consciousness in its detail, by a fairly complete description of the process. But that still doesn't explain consciousness as a subjective experience.

The paradox is that I can observe and measure someone else's unconsciousness but I cannot observe and measure my own. I can only experience qualia when I'm conscious. I can only describe qualia to another when I'm conscious. So the question becomes; can we understand Q if we can never experience or describe not Q? Is it hopeless to try to understand the "on" state in its own terms when we cannot measure or observe the "off" state?

I'm just asking the question.

While I used the term "paradox", it's only appropriate if we don't allow an exception for the first person perspective (reflexive discovery).

Premise: I can discover if any person is conscious or unconscious.

Premise: I am a person

Conclusion: I can discover if I am conscious or unconscious.

This should be true if we do not recognize a special case for reflexive discovery. Obviously we do and that's the point. It's not clear to me how this paradox can ever be resolved. It seems that qualia are certainly real. Who wants to argue that pain is not real or that it cannot be described and evaluated? However it is an entirely subjective internal experience (except perhaps for one retired US president).

I haven't read the literature that's been cited in this thread, but from a scientific perspective I see no way the usual scientific methods can be applied. Perhaps someone can suggest where I'm wrong. Remember, we are not talking about observable physical correlates of qualia, but the qualia themselves.

fine. if we lived the exact same lifes it would be presumable our consciousness wouldn't differ a great deal. what I've studied simply states that people generally behave the same way. its when you add environment, religeon, education, hardship, or any diversity, that makes us different. this gives us a sense of self, individuallity. it is unnecessary for our existence . if we left all the b.s at the door we would probably both get hungry, seek shelter, find mates, even sleep.

I doubt it. What you suppose is that all human instinctive behaviours are the same. I am interested to know what discoveries future scientists will make when we have mapped the connectome, especially with regards to our genome. Instinctive behaviours are created by our genetics causing the ordering of our neurones in specific ways, as our genomes differ I would argue that our instinctive behaviours could too.

you're arguing using spuculation? how am i to take you seriously? i just brought up taoists because they studied human nature and consciousness for centuries before western civilisation even existed. why should i believe you over them?

What on Earth are you on about? Where did I speculate? Taking away personality/memory we are left with instinct are we not? Instinctive behaviours are genetically coded. Genomes differ from individual to individual and across time (i.e. evolution). So between individuals and across a species evolutionary history instinctive behaviours differ.

Taoists have not studied anything about consciousness. They have philosophised over it but there has been no study, study in the manner we are talking about requires some experimentation. You don't have to believe me but you could at least learn the science of what you are trying to talk about.

i've studied this forum for a few hours every night with links to wiki and other forums. I've read papers by brilliant people. nothing I've read gives me an iota of practical information about my consciousness. plenty of theories out there though. on the other hand I've found meditation useful to partition my ego and consciousness and have seen the effects on my life. i know anecdotal evidence is frowned upon here but i have a system that is used by many people around the world,myself included, or theories and waiting for answers. i go with what gets results. that, to me, seems logical. call me a crackpot if you will. when that study gets results post alink and i'll check it out. till then i will continue becoming a better person by reducing my selfishness. there may be some scientific equation in there if you analyse hard enough.

if you take out the part giving credit to taoism is this really any different than the conclusion mainstream science offers. maybe a link or a few links that can agree would help.

I don't believe that it is "an entirely subjective internal experience". I believe pain is experienced in more-or-less the same way by the majority of the population. That's what allows us to talk about it and measure the physical correlates.

I don't think it's too far of a stretch to say: if you want to know what it felt like for Phineas to get a spike in his head... get a spike in your head. Can't we all agree that it must be a much closer approximation to what Phineas Gage experienced than getting a brain freeze from a slushee?

I haven't read the literature that's been cited in this thread, but from a scientific perspective I see no way the usual scientific methods can be applied. Perhaps someone can suggest where I'm wrong. Remember, we are not talking about observable physical correlates of qualia, but the qualia themselves.

It's not impossible to explain your perceptions (a tingly feeling crawling up my arm). Or what about heart break? If you've ever experienced it, "a sunken feeling in my chest" is appropriate (and possible contributed to why the ancients thought the heart had a brain's role in emotional experience, as the opposite fluttery feeling of love/infatuation tends to be perceived in the heart as well... generally because it's trying to jump out of your ribcage. Good think for the buffer zone.

Anyway, are qualia and perceptions really unique to each person and completely subjective? We don't really know, but I doubt it. I think the only real difference is the quanta of the qualia (i.e. same thing, but to a different degree... so two different healthy people have the same general experience, but particular aspects are more intense to one person than the other so the emergent experience may be different.

Since this discussion has been reopened, I want to make more rigorous my claim that while qualia, as the elements of subjective experience (consciousness), are real, they can only be studied indirectly from the third person perspective. Put quite simply, I cannot feel someone else's pain. My attempt to put this in the form of a syllogism in post 22 was loosely based on Russell's paradox. This was a profound logical result which altered the way the foundations of mathematics were and are formulated.

The original paradox was quite simple. The barber only shaves everyone in the village who do not shave themselves. There's a hidden assumption that the barber is resident of the village. So who shaves the barber? If he shaves himself, then the premise is violated because the barber only shaves those who do not shave themselves. However, if someone else shaves the barber the premise also is violated because that person is supposed to only shave himself.

Now say the barber only shaves all patients in the hospital ward who do not shave themselves. All the conscious patients in the ward shave themselves. The barber is also a patient in the ward. Who shaves the barber?

In both cases, as in my original syllogism in post 22, the paradox is removed if we remove the subject from the set. In mathematics this means there is no universal set (a set of all sets). In the present context, it means that the observer/actor cannot be part of the set she/he is observing or acting upon. I can always determine whether anyone in the set is conscious or unconscious only if I am not a member of the set.

Some years ago I was studying neuroscience modules during my Bsc whilst my partner was studying philosophy of mind. We had many conversations about qualia and how one cannot experience another persons experiences. To this I proposed that this may not always be true, if we could accurately map a neural circuit in one persons brain and cause the rearrangement of a circuit in another persons we could hypothetically transfer the experience.

If you went out and did something an then using our hypothetical advanced knowledge of neuroscience we recorded your thoughts/feelings/memories to my brain would I not have experienced your qualia?
