A Mind Made From Memristors

Csiko writes "Researchers at Boston University's department of cognitive and neural systems are working on an artificial brain implemented with memristors. 'A memristor is a two-terminal device whose resistance changes depending on the amount, direction, and duration of voltage that's applied to it. But here's the really interesting thing about a memristor: Whatever its past state, or resistance, it freezes that state until another voltage is applied to change it. Maintaining that state requires no power.' Also theoretically described, solid state versions of memristors have not been implemented until recently. Now researchers in Boston claim that memristors are the new key technology to implement highly integrated, powerful artificial brains on cheap and widely available hardware within five years."

        No secret sauce here. You're dancing around an argument, but let me try to add some clarity:

        If a machine (of any construction, even bio-ware) was grafted into your existing brain, as to replace/extend it's normal functions, you may or may not notice at all. Nobody really "feels" when a specific set of cells in their brain is different, as they "feel" a cold/hot spot on their hand. It's much more about the perceived functionality. A headache or an itch is as more perception than a true "pain spot" or "itchy spot". Brain surgery requires only local anesthetic.

        If we continue adding externally-created parts to your body, be it an arm or leg, a lung or a kidney, or a frontal lobe to your brain - if the body can accept the donation without too much trouble, the functionality should not be affected. This is the only criteria for the replacement part: It has to function identically as it's target. But for brain wiring, it's millions of times customized from the point of it's first growth. Reverse-engineering this wiring seems daunting. But perhaps "you" don't notice if the changes are small enough.

        So we replace sections of our brain one step at a time; small portions, throughout time. The first recipients get better hearing, motor control, or other medically-driven needs. Then we hopefully add larger portions in bulk. Once we start replacing the emotional centers, memory centers, or other portions, you may start to no longer "be you" as you don't remember your childhood, or your demeanor is dramatically changed from before, but the frame and power sources are indeed still your biology. Personality adjustments by order.

      I imagine any replacements of brain portions will involve a period of "adoption" where the new section needs to be immersed in the dispersed, repetitive memory wiring that gets done throughout REM sleep. Of course, by this point we should be able to induce it, hopefully speeding up the process. This would be the holographic-style process of "maintaining you" while slowly replacing all the hardware.

      The elusive sense of "I" that seems to arise from the brain as a whole would have a central locus and that may need to be replaced in very small chunks, or possibly not at all - depending on how universal that wiring is across all our brains and how the replacement adapts after injection.

      This is the fundamental assumption you're making that drives your argument: that the soul is distinct from the body. Go look up 'dualism (philosophy of mind)' on Wikipedia and you can read all about it.

      Of course, there's no evidence of this actually happening, as any hypothetical soul is unobservable. Every now and again somebody wraps the same argument up in quasi-scientific terms, usually using the word 'quantum', but right now dualism is a null hypothesis, untestable and therefore fundamentally uninteresting.

      However, if the state-of-the-art eventually does allow us to duplicate a brain, suddenly dualism does become testable (at least, provable; not necessarily disprovable).

      To make the point more clear, what if I made an identical copy and booted both at the same time. Do you suddenly develop a psychic link with your other self, experiencing both existences at once, living in two different places? ... ridiculous.

      If dualism is true, then there are three options: firstly, you retain the soul, but the copy has no soul. In this situation the copy won't work (this is an assumption, but if an ensouled brain behaves identically to an unensouled brain, then the soul is irrelevant). This is really interesting, because the body is a fundamentally material construct, and so this gives us a way to investigate how the soul interacts with the body, and could even lead to a science of manipulating souls. (Whether this is a good thing I'll leave up to the ethicists.)

      Secondly, the copy gets the same soul as you do. This means both you and the copy end up being the same person. This pretty much leads to, as you say, a psychic link (because otherwise you and the copy would have divergent experiences, making you different people). This is also really interesting, because it gives us another (different) handle on how souls behave. If we separate you from the copy too far, does one of you die because the single soul can't 'stretch' between the two bodies? If so, how far? If not, is there a light-speed lag in information transfer? If there is, how does the soul retain coherence? If not, does this violate causality? What about relativistic effects applied to a single body?

      Thirdly, the copy gets a new soul, acquired by whatever mechanism binds souls to infants. This is less interesting, because it's indistinguishable from the non-dualist case (see below). However, if the new individual turns out to differ from you in ways that can't be explained by divergent experiences, it does give us a weaker but still interesting handle on soul/body interactions by investigating why they differ.

      If dualism is not true, then the mind is encoded entirely in the state of the brain, which is being duplicated: so what we end up with are two yous, each believing they are you and with continuous memories of being you.

      If you're interested in this stuff, I suggest you go out and read Greg Egan's Permutation City. Or Dispora. Or Schild's Ladder. Hell, basically any of his books, although he does explore the question from the non-dualist point of view (but in very interesting ways).

      No, not ridiculous, quite simple really. YOU would awaken once the switch was flipped to start the processing of your newly copied electronic brain. This new you would have the same memories/experiences you had when the snapshot of your organic brain was taken. Now, assuming your original organic brain was not instantly destroyed when the snapshot was taken and is still functioning, YOU would go on as if nothing happened. Your electronic brain "clone" would do the same, only from the very instant it became concious, it would begin deviating from the original because it would begin absorbing a separate set of experiences. If you were to, a while later, sit down an converse with your "clone", you would undoubtedly feel a tight kinship when it because of the share memories, but it would be a relationship more akin to a close twin. Basically, we are our memories, no soul or special spritual sauce required. While the idea of (at least momentarily) there being two "YOU"s with exactly the same memory might seem odd, if you think about it there's really nothing special about it. It's no different than my having two copies of the same file (in computer terms). It is exactly the same configuration of bits, even though it exists within two separate media locations. Once I alter even one bit however, it becomes a separate entity.

If I copy your brain to another cloned brain, yank yours out, and replace it with the clone, everyone else will interact with you as if you were you, no difference; but YOU would vanish into the blackness, you'd stop living, you'd die.

      No, I don't so, anymore than receiving a heart transplant changes the way you feel about your loved ones. You'd continue on just as before, only you'd be "running" on a new brain. The same would be true if brain transplants were viable and your brain could be removed and placed in someone else's body. While your physical body would be different, the mind within your brain would still be you.

      Your brain is simply the hardware that you are implemented with. If an exact copy of your brain structure, along with all neuruonal connections and states can be replicated and placed into another brain or electronic device it would, by all accounts be you. The difficulty in imagining this is the idea that somehow there is something special (spiritual) going on, and that "you" are somehow unique and separate from you physical implementation. When in reality it is just as you mentioned, just a configuration of chemical and electrical states and processes.

      Keep in mind that neurons (and their related connections) have been dying and getting replaced your entire life. You are no longer the same set of cells you were when you were young, but you still feel like the same person (at least to a certain extent).

      Conciousness is actually fairly well understood nowadays and doesn't really require any metephysical explanation.

      Consciousness is simply a "state of attention" that is produced by the processes going on in the brain and is primarily a function of the hippocampus (a walnut sized kidney shaped organ deep in the center brain). Consciousness is merely the collection of thoughts that your brain is primarily focused on at any given moment, with the most pressing thoughts receiving the most attention.
      Think of it this way. Imagine you are absorbed in reading a book while walking down a flight of stairs, (assuming you are somewhat coordinated). The mechanics of walking down the steps will be managed somewhat automatically by lower priority thought processes and your attention will be focused on what you are reading - no problem. Now imagine that you miss a step. You immediately switch your attention from what you are reading to trying to catch yourself. What you were reading gets pushed down in priority and the hippocampus diverts all attention to the motor cortex so that you can try to keep from busting you ass (it also dumps copious amounts of adrenaline into your cortex so you can react quickly). This amounts to a radical reorganization of your thoughts. After you recover, it will take some time for the adrenaline to dissipate so that you can go back to focusing on your book.

      If you try and recall what happened, it will seem almost as if the near fall happened to someone else. You will feel somewhat disconnected from it. This is because the "stream" of consciousness was broken and a new stream started. What this tells us is that (in the mind vs brain sense) there is no "you" or "me" in a static context, just like it's not possible to separate space and time. Who you are is constantly changing, with every modification of the synapses in your brain. Just as your mind underwent a major change when you almost fell, switching off from my organic brain into an electronic would result in the same sort of context switch, but I would still feel like "I" was "me".

      As for the angels, I brought that up because from a spiritual perspective I would feel that a very fundamental thing in human spirituality is "knowledge of and closeness to god/the source/whatever". It's not something that I can explain, being in it's nature something like being musical or tone-deaf, but I think you get what I mean. One view of judeo-christian angels is that they have no free will and perfect or near-perfect knowledge of god, yet are indeed "separate". This would then imply, as you well understood, knowledge instead of "suspicion" - my thought was that of kinds of being that had a fundamentally alien perception in these regards, but such an angel might have been a bad example because the being imagined would simply have a "perfect human" closeness, union. I can't come up with any good examples, but postulate a creature that somehow has an intuitive understanding like the one we are discussing in such a manner that it is meaningful to compare the two, not "stronger" or "weaker" but so different in it's fundamental nature to that of a human mind that it is completely incomprehensible.

      My understanding of your argument basically boils down to the fact that replacing the physical matter or structure of the human brain will render the material end of the "relationship" null, because the "soul" and the brain grow and function together and are inseparable as far as that goes. My counterargument basically boils down to the fact that we are already doing so by crudely interfacing with the brain, because I see no difference between changing sensory processing in this manner and changing cognitive processing. Changing the cognitive processing will simply result in a being with a "host form" that implies a conciousness removed from human nature in fundamental ways, including aformentioned spiritual aspects, at least on a level above "pure intuition".

      As for the actual brain/machine transfer, if the "standing wave" of conciousness is preserved such that it "remains attached" and "enters and possesses" the new or modified parts during this change, that changed part is now a part of the host form. How far we go from there depends of course what parts of the intellect we pick and choose as constituting the "essential nature" of the intellect in question. If you just cut off a piece of brain and interface the rest with a machine, the parts of the "standing wave" that was "attached" to the brain not cut off will interface and expand into the machine, making it part of itself. You could duplicate a "wave" and create an identical copy, but the waves remain separate unless made to flow into each other - merging and splitting (partial or whole) becomes possible because from both parties perspective that's just another form of smooth change without loss of information. As for the post-mortem aspects, well, the only humanly graspable solution if you want a real "afterlife" is clearly some divine janitor sweeping up the "astral mirror" pieces of lost information (or whole lost independent sub-creatures) and reassemble/integrate them piecemeal together and, it is commonly assumed, in a more or less tight fashion with "god".

      I think it's exceedingly unlikely that humans are non-deterministic, but I also believe it's irrelevant.

      First, here's why I think it's unlikely: There is very little evidence that conscious behavior is random (and mounds of evidence to the contrary), and even less evidence that "random" unconscious behavior is a truly random rather than pseudorandom (unpredictable but deterministic). To distinguish the two requires repeatability; something which is currently impossible in measuring human behavior due to the complexity of variables and our inability to control for them. Think of it like dropping a leaf -- its trajectory will be subject to innumerable variables and parts thereof, including wind speed, air flow over its surface, orientation upon release, and any momentum imparted by the release itself. As such, its fall will be unpredictable, but only due to lack of data, not lack of determinism. Start controlling for variables by, say, dropping it in a vacuum, and the results become much more predictable.

      Since all behavior at the macroscopic level is deterministic (and by behavior, I mean physical processes, and by physical processes I mean anything other than "supernatural" events), then the extraordinary claim that humans are non-deterministic requires extraordinary evidence IMO, which has certainly not been met by any study I'm aware of, and would certainly be front-page news if it existed. As such, assuming that the brain is deterministic, then any variables which can be defined and measured can be also replicated or simulated. It may well be that human consciousness is the result of much more than simply the mechanical structure of neurons (and I believe that's highly likely, the same way a video game is more than the structure of the components in your system), but complexity is not randomness, no matter how similar they appear.

      Finally, the reason it doesn't matter whether or not randomness is an issue is that any system could be designed to include randomness if it's found to be relevant. Randomness is unpredictable (non-deterministic), but its influence can still be measured and its effects and limits can be quantified. For example, a random error could cause an improper bank transfer, but the limits to that error are whatever the maximal values are for the computers involved. The effects would be an unexpected balance change, and they are easily quantifiable and, since banks don't like errors, correctable. But there's no physical imperative that they be corrected, strictly speaking. We could simply allow for randomness in banking if we so decided. I suspect that we won't value randomness in consciousness simulation/replication, but if we do, it's easy enough to add.

      First of all, you're correct. The pronouncement that IBM made in 2009 of having built a cat-scale brain was BS and the head of the Blue Brain (Henry Markram) project was quite upset that IBM had over-hyped the achievements and did what he could to lower expectations. I didn't realize this was the case. The link I posted was one I goggled without reading in full, having read a similar story quite a while back without the points you mention.

      However, I still do not share your pessimism on the subject.

      The original, over-hyped "cat-brain" announcement was from 2009, but since that time considerable progress has been made. The first of a series (Year One) of documentaries has been posted on their web site ( http://thebeautifulbrain.com/2010/02/bluebrain-film-preview/ ) summarizing where they are as of April of 2010. Markram is predicting completion of a simulation on the scale of a rat brain within 2-3 years (around 12:00 into the video), moving on to a cat brain and eventually to primate and then human scale brains. To reach the human scale, he is somewhat vague on the timeframe, but 2018 is the expected completion date for the entire project. Now, just to set expectations; it may be that the end result of the project is a human brain simulation that runs hundreds, if not thousands of times slower than the human brain, but that does not invalidate it's usefulness as a tool to study and learn from. One of the biggest stumbling blocks to understanding how brains work is that it's hard to experiment on a living brain without altering it (i.e. damaging it) as well as trying to obtain results from it. This simulation will be of tremendous help in medical research as well as in cognitive science. Hardware and algorithms will improve and this gap will narrow until at some point (I have absolutely no doubt) parity with the human brain will be achieved and undoubtedly surpassed. There is just too much to be gained by doing this and as we get closer, it's importance will become more and more apparent, spurring more intense development from all the cognitive science , engineering and related disciplines. I expect this will be similar to the Human Genome project which was completed well ahead of schedule due to methods learned and advances in technologies that were not originally anticipated. Additionally, accurate simulation of a single cortical column is a huge achievement and it's taken a long time to get there, but this has now been accomplished. Because much of the brain is a mass duplication of nearly this same structure over and over again (approx. a million of them in the human brain) scaling this up will move much faster than getting the first one built.

      Additionally, this is just one of many projects that are attacking the problem from many different angles. I've been following this type of research for many years and while its had it's highs and lows (rapid progress followed by seemingly no progress) and never before have we progressed so far so fast.

      One more point. You're argument about analog v digital is a non-starter. We've been simulating analog systems for years using digital computers (e.g. that mp3 you're playing is digital, but sound is analog). There is no reason to think that an analog system is a requirement for generating intelligence, it's just a matter of how much digital computing power can be thrown at the problem. Memristers simply hold the promise of lowering the power requirements (both in terms "energy" required as well as "computation").

      In any case, thanks for the interesting discussion.

They have no capacity for memory or reasoning which are essential elements of "true" intelligence. For this, we need higher brain structures and for the purposes of trying to understand human intelligence, we need to understand the cerebral cortex. This is the part of the brain where intelligence is originated, rather than just hard-wired instinctual behavior. Low order mammals such as the mouse is (IMHO) the right place to start because it has a cerebral cortex, though it is much smaller in proportion to the rest of it's brain than higher order mammals, it is structurally similar enough that what is learned there can be applied to other, higher level species.

      Sure, one could state that even a microbe has some form of intelligence (e.g. an amoeba in a pond will swim toward the more nutrient rich part of the pond), but while it's important to study and understand how it navigates through its life, it doesn't really address how cognitive function is implemented in a biological entity.

We learn through input, the more information we feed on the more efficient the machine we become. We are now in a trend where we are de-evolving technologically. Actually discovering inferior technologies to compensate for the flaws that we as superior tech are hardcoded with. Like our inability to cheat death, and our inability to keep our system from degrading. Life compensates for this by allowing us to transfer our most vital information through DNA adding information along the way. This isnt good enough for us. We, unlike most computers, have the ability to overcome obstacles set in our path. One could argue that this is a preprogrammed skill set. Much like a complex computer application which is designed to react depending on the external stimulae.. I dont prescribe to the soul idea. I do believe however that man is just a shell like a PC case to house all the data we harvest. I dont know what happens when the physical body dies but I would suspect that the pure information we are composed off exists in some form or another.

    This entire article reminds me of that crackpot researcher Hugo de Garis, who wanted to build an artificial cat brain about a decade ago. I don't understand that people or organizations like DARPA still fall for this. Let me spell it out:

    It makes NO SENSE to try to build / simulate a human or cat brain if you don't understand its underpinnings. The 'magic' of the brain is not in the neurons, it's in the wiring. Until we understand how a simple brain (like that of an ant) works we shouldn't be trying to build a more complex brain and hope it will magically start working when we flip the switch.

    You have no idea of what you are talking about. Get a degree, read a few neuroscience, computational neuroscience, robotics papers, and then read the article again, you might learn something. You are still in the stoneage

    http://tech.slashdot.org/comments.pl?sid=1891254&cid=34413838 TheEndOfDays likes stalking and trolling others (as well as starting it up as shown right there)? I like how he was put into his rightful place here in the end http://tech.slashdot.org/comments.pl?sid=1891254&cid=34418274 where TheEndOfDays ran like the trolling little coward he really is, unable to back up his trolling and stalking crap. TheEndofDays, it seems that You like starting up hassles, but in the end, you always "eat it". You're also too lazy and ignorant to volunteer to do anything, other than being caught trolling and stalking others here as you were in the URL above, clearly.
