"Hybrid Consciousness": an object for thought experiments

Imagine a hypothetical situation where a brain and an artificial device are coupled in such a way that a single consciousness (a single subjective reality) is associated with them. Let's call this a "hybrid consciousness" (perhaps, a better name can be suggested for this).

One can do various interesting thought experiments with such an object. The contexts where this might be useful include the abstract topics such as "Hard Problem", technological singularity, or uploading, and more practical topics, for example, something like "if I could change a way I am [reading mathematical papers/writing computer code/...], how would I want to do that, and what would I want to feel in the process of doing that".

1) In context of the "Hard Problem", I think the ability to achieve a situation like this would be the best test of our understanding of the "Hard Problem" (and would make the subjective realm much more amenable to tests and experiments).

Here we must assume that a sufficiently non-trivial part of a given subjective personality is associated with the artificial device (and, for example, when the body gets sleepy, we are likely to observe the shift of the subjective towards what is mostly running on the artificial substrate; and if the coupling remains during sleep, we might get some version of lucid dreams as part of the overall activity).

2) In context of mind uploading, this seems to provide a much saner approach that what people usually discuss; an example of an approach along these lines is here:

http://www.aleph.se/Trans/Global/Uploading/gupload.html

3) In more practical contexts, the question what would I want to feel in the process of doing [A/B/C/writing computer code/reading mathematical papers/...] makes sense on its own and might be useful to consider.

4) We can also ignore the fact that we don't know whether one can use an ordinary computer as a device coupled in this way to a human brain, and even if the answer is positive, that we don't know what would it take to achieve a coupling like this (both depend on what the answer to the "Hard Problem" really is), and ignoring our lack of knowledge here we can try to meditate on how we might want to program the computer to do this or that, if such-and-such layer of the processing were conscious. (Ignore the fact that without further progress on the "Hard Problem" we don't know how to distinguish between conscious and unconscious processing; and decide that we have some freedom is designating some views into the running system as conscious.)

5) One also has some freedom to run things slower or faster in the artificial device, although if one wants to preserve coupling with the biological there are probably some constraints. When I start to think/introspect about accelerating some parts of the train of conscious thought relative to other parts, what I mostly feel is cognitive dissonance, so I am not sure whether this direction of thinking is fruitful (в этом месте, оно несколько сносит крышу).

I am not sure how much of the above makes sense, but I was thinking about this topic during the previous week and have not lost interest, so I decided to share this.

Not really, no.. Everyone is so happy to focus on the evidence that we are getting two different persona there, that not much is told about feeling.. (Of course, the interaction is mostly with the "left-brained one".)

I mean hemispherectomy, i.e., complete removal of one hemisphere. I wonder whether they feel themselves differently after this surgery (apart from the evident issues with one side of the body).

ah, with one hemisphere left.. probably quite horrible at first (given both all the one-side issues, which are especially horrible if the "left hemishpere" is removed, resulting in the loss of language and complete disability, and post-surgical recovery), then they adapt somehow..

even if the "right hemisphere" is removed there is a complete loss of certain functions, e.g. artistic perception must suffer drastically.. this ought to be felt differently..

Horrible, but the question is whether they feel THEMSELVES any change of personality apart from the one-side BODY issues. I was surprised that these people sometimes have normal life and even write about it...

Although split-brain patients deny that they are two persons, as far as I understand, so such testimonials are...hm...unreliable...or do they still have ONE person to a certain extent?..

If we remove the "left hemisphere", they don't get to write or speak ever again. If we remove the "right hemisphere", and the person was "left-brain oriented", then yes, I can imagine that they would ignore the differences (especially given that the memory of the earlier state is very impaired, so it's difficult for them to compare)..

With the split brain patients we mostly interact with the "left-brained one", the other one cannot speak or understand language, so the interaction is difficult.

Anyway, the left-brained person declines that there is someone else there(?). Unfortunately, there are too few investigated cases, and, as far as I understand, none of the patients was a biologist or, at least, a mathematician...

Yes, they do not communicate usually.

A contact with someone, who does not have language, is difficult.
