Scientists Afflict Computers With Schizophrenia 143
An anonymous reader writes "Computer networks that can't forget fast enough can show symptoms of of virtual schizophrenia, giving researchers new clues to the inner workings of schizophrenic brains, say researchers at the University of Texas at Austin and Yale University. In their experiments, the scientists used a virtual neural network to simulate an excessive release of dopamine in the brain and found that the network recalled memories in a distinctly schizophrenic-like fashion. The results bolster a hypothesis known in schizophrenia circles as the hyperlearning hypothesis, which posits that people suffering from schizophrenia have brains that lose the ability to forget or ignore as much as they normally would. Without forgetting, they lose the ability to extract what's meaningful out of the immensity of stimuli the brain encounters."

the medications supposedly help erase memories. at least my nurse seemed to think they do. In my case the medications seem to help, but I wouldn't stake anything important on so called anti-psychotics or even atypical anti psychotics either.
in my case i drink heavily filtered water, avoid most sugar natural or not, and avoid artificial sweeteners, avoid all caffeine, and the only thing i noticed is my thirst dropped 50% and devoid of caffeine and sugar that i get less dizzy from my medications. i also have an increase in my conscious. e.g. i am now extremely worried (but not paranoid) that i bragged about knowing things i didn't know at the time, and i realized i was asking for things i didn't need or want in my life. if i could change the past i would undo asking for things i didn't need or even want, it was like someone thought i needed to have that kind of thought and made me think it for myself.

Do schizophrenics typically have eidetic memories? This is not a symptom I was aware of.
I've often read that remembering something is a constructive process. I tend to think of it like checking out a revision from source control software. All it has are a bunch of diffs and pointers, and it executes a process on them to construct a snapshot of what the code looked like at some particular time. From that perspective, the snapshot is a new piece of output, even though it's cached information from the user's perspective. Human memory is said to work the same way: it's reassembled, not retrieved.
So, if a person has eidetic memory, then one would expect them to have a better than average "ability to extract what's meaningful out of the immensity of stimuli the brain encounters". On the other hand, since a defining trait of eidetic memory (as the term is often used) is being able to recall any detail and not just "what's meaningful", it must also entail exceptional ability to store and recall mass amounts of raw data (the diffs and pointers in my analogy). But nonetheless, I'd expect them to be exceptionally strong at filtering and reconstruction as well if they're able to form that data into coherent memories and verbalize them.
Then I suppose the hyperlearning hypothesis is saying that the reconstruction process breaks down because the data is too abundant and disorganized. Maybe I can extend the file storage analogy a little further: a hard disk that's so full that you can't defrag it? Or one where deleted files stay behind and come up instead of whatever you tried to overwrite on those disk sectors? Corrupt file system table?

Over time both brown and white matter volume go down (note this is volume of matter that's observed, not number of neurons.. at least for a good good while)
(though they say 'neuro toxicity' it's a load of unsubstantiated crap)
Oddly, new research has shown that neurons migrate to points of higher entropy to solve problems then migrate back again if their not needed, possibly self terminating if there really not needed. Also that memory's are related to density...

That would also relate to and increase in white / brown matter as the entropy of thought was on those areas (origin and difficulty connecting them).
What they do is give people pills that make them chronically retarded and ignorant (hey ignorance is bliss) and oddly when you try to stop the brain working it seems to fix things (bullets in the head also have this effect and less patients have complained).... There is an 'ethical' (NEURO TOXICITY) ban on doing any research into any kind of alternative treatments (like 'stress reduction, education, meditation techniques, progression etc...).. in-fact they try to put people on them at even the slightest whiff on anything that may turn them into the next John Nash (since we can't go giving Nobel Prizes to any more mad people)
Only other real indicators are 'stress' very strong correlation and mioline (Lorenzo save me and my bad spelling)... and frontal lobe...
The frontal lobe is strongly related to 'mirror nurons' (look that up, recently released info) that basically relate to your sense of self and other people. Also related to psychopathy (ASPD)
Recently rejection [I don't think your ideas are worthy, F-] has been directly linked to the area of the brain that pain from heat is linked to.
Lack of miolin makes your brain work slower, so quite why their using that as a treatment method when it's an indicator fuck only knows...

You ignore and quickly forget the information that isn't relevant and retain and think about that information that is is. Eidetic memory would allow them to retain all the information but still ignore what didn't matter. If they needed to, they could pull up what colour shoes they wore at age 12, but they would be able to determine that this information was "not important". Hyperlearning says that schizophrenia prevents this so that you can't tell the difference in importance between what you had for lunch last week and what you got on your last math test. This means that your brain is overloading itself trying to figure our WHY all these things matter and piece together connections between them when it shouldn't be.

I think it pretty much is. 'Forgetting/remembering' at the neurological level is an emergent property of millions of neurons selecting salient information from their incident stimuli. What ends up being encoded into long term memory is a collaboration of each of these neural networks working on their piece of the 'salience' puzzle. The salience can be evaluated in a number of different ways - is it emotionally significant? is it practical information? But, actually, this research concerns even more basic evaluations, such as 'What are the basic grammatical structures in this sentence? What are the words, what are their meanings and how are they arranged? What is the content of the sentence as a whole?" If the wrong information is thrown out *or* remembered, it becomes very difficult for the brain to make sense of it.
So forgetting/remembering are, in many ways, the same thing. In the process of remembering, we have to forget, or our memories quickly become incoherent.

Except that the "dream function" is merely the brain's attempt to continue living in a way, recreating reality when your conscious shuts down and you're no longer consciously receiving sensory input with which to interpret a reality. I'd say that makes it the reverse: The dream state doesn't "[slip] into the conscious state", rather there is a failure to separate imagination from sensory input.

It's not easy because it requires a lot of working memory, but the speech is usually not completely incomprehensible. Of course it really depends which type of schizophrenia you're referring to.
The communication style itself depends heavily upon a large memory capacity and increased ability to infer meaning. I don't personally have enough experience dealing with folks with schizophrenia to really know how accurate that perception is, but my observations would definitely be consistent with that.

I find the summary a bit confusing, though. What I have heard before is that the schizophrenic brain is poor at filtering out stimuli, meaning that unimportant details will stand out as much as important ones. For instance, it might have trouble filtering out ambient noise, so whereas a normal brain will cut off processing early on, a schizophrenic brain will process the noise the same way it would process salient, meaningful sounds. So what might happen is that the phoneme processing part of the brain will receive ambient noise as input and will make out voices and whispers out of it, because that is its job, and then these will be manipulated and interpreted as a conversation - maybe neighbors plotting against you, because why else would you be paying attention?
Stimuli that should never make it past saliency processing get dispatched to the brain, which assumes that if it got this far, it must be meaningful (this is normally a fair assumption). From then on, it will "learn" to find meaning in noise, hence visual or auditive hallucinations, delusions, etc. From what I can gather, this study shows that an excess of dopamine could inhibit normal filtering functions, hence the "hyperlearning" on stimuli that should be thrown out, but isn't.

Actually, I have an issue like this that makes me very uncomfortable around crowds. For example, when I go to a restaurant, I can hear every conversation going on around me with the same relevance as someone sitting next to me. It drives me nuts because it prevents me from enjoying a conversation with the people I actuslly care about. In that situation, I either have to process everything at once and parse out the stuff relevant to who I'm trying to talk to, or block out everything as white noise and not participate at all. I also get a bit nauseated from dealing with so much info at one time.
Needless to say, I don't go out much and prefer to be in locations where I control the environment. Usually keeping things dark and quiet.

Someone spoke on the phone is a South Asian language that was "ambient noise". Why didn't I think that Indian lady was plotting against me?
1) GP was talking about people with a brain dysfunction. That is to say, whose heads are not functioning normally. That said...
2) You don't think she's plotting against you because you have no reason to suspect so. If you'd been hearing unintelligible whispers all day, hushed voices in every shadowy nook along your route to work, and they seemed to sound much like her voice as you hear it on the train, you might consciously suspect that you were being followed and begin becoming paranoid, especially if you had begun to panic earlier in the day (violent sounds and then what sounds like laughter, or other evidence of being hunted/tailed, etc). If your anxiety really begins to rise, it can be very easy for conscious logic to fall by the wayside. If this happens every day for months, you could be a goner.
Which is to say, one or two faulty parts in a brain can be enough to screw you up. Aside from thinking you hear whispers (and other paranoid affectations), you'd be just the same as you are now, only you have reason to suspect things that just plain aren't true, and you can't find a way to go back to where you were before you started hearing them, because it's a brain affectation and not a mental one (presumably).

The brain is not monolithic, it is comprised of many parts and many layers that communicate with each other. I might have spoken vaguely, but the basic idea is that irrelevant stimuli is reaching parts of the brain that should not be receiving them, due to failures in the gateways that are supposed to filter them out or redirect them to parts of the brain that are meant to deal with noise. All these gateways are technically part of the brain, but it makes sense in my mind to separate the "routing" subsystems of the brain from the "processing" subsystems.
In your example, you could imagine that stimuli is routed through many places in your brain, including filters that will make a very rough analysis of the signal and determine whether you are hearing a language you can understand. Thanks to these filters, the language processing part of your brain will receive in priority all the English sounds, and the South Asian sounds will be blocked from being processed that way. You still hear Hindi, but the autopilot that analyzes English and other languages you know is never triggered. Over time, your brain might carve a subconscious circuit that will automatically notify you that "Hindi is being spoken", but that will be a separate circuit that does not interfere with others. Until you actually learn Hindi, the core "language and meaning processing" module of your brain simply never sees it.
In the case of a schizophrenic person, the Hindi might get through to English language processing, and that part of the brain, which normally operates under the handy assumption that it is analyzing English, will make them hear sentences that are a loose compromise between fitting the noise and being coherent. In general, the brain is comprised of many highly specialized parts that do an excellent job at analyzing certain particular kinds of data. In order for it to work as smoothly as possible, data has to be routed smartly and parsimoniously so that the right kind of data is given to the parts that are specialized for it. The idea is that letting spurious signals seep through to the parts of your brain that analyze salient events = schizophrenia. In other words, a schizophrenic brain, in some sense, might inadvertently assume it knows Hindi, because language-like signals indiscriminately fall through to meaning analysis, without the safeguards normal brains have. Obviously, it will do a catastrophic job at understanding it, but it might not have the resources it needs to figure out there is a problem at this level, so it will "adapt" in somewhat random ways, paving the way to even deeper troubles and madness.

Forgetting dreams (Score:2)
The problem with schizo people is not that they have too many "normal" memories. But that they remember too much of the "wrong" things.
Have you ever woken up from a dream, and had difficulty, at least for a few moments, figuring out what is real and what is not? After those few moments, your mind clears, and you realize that your dream made no sense at all, and you wonder how you could have ever thought it was real. By the time you finish breakfast, the dream is forgotten.
This is what schizophrenia is like. Except your mind doesn't clear, you don't forget, and you don't stop dreaming when you wake up. I think the cure to schizophrenia will come when we find the brain's "time to wake up" switch, and figure out why it doesn't always work.

I/O Logic for "hyperlearning" "learning" to occur there are two requirements acquisition and application.
IOW: Acquisition of knowledge/experience with no skills to apply knowledge/experience cannot be learning. All learning requires test/eval application of the knowledge/experience acquired. Learning can be theoretical/abstract/art... and/or applied/practical/task... and provide value to at least the learner.
So, "hyperlearning" does not exist for persons in a fugue/schizophrenic state. They cannot apply acquired knowledge/experience and are not expected to apply knowledge/experience. A surgeon/engineer that has amnesia and/or schizophrenia cannot appropriately apply the acquired knowledge/experience.

Forgetting ~~ stabilizing negative feedback? (Score:3)
It sounds like too much remembering induces positive feedback in the brain's pathways which lead to unstable oscillations. Forgetting is then required in order to dampen the system and stabilize it.
If the brain remembers too much, it's possibly not the new stimuli which overwhelm it, but the combination of new stimuli plus the remembered information being replayed, all made worse by feedback paths.
Just a wild-assed hypothesis.
Connectionism and encoding meaning (Score:1)
I posted the following comment on neuroskeptic about this article:
`"Noteworthy was the high frequency of agent-slotting exchanges between the hospital boss, Joe, and the Mafia boss, Vito, and parallel confusions between the “I” self-reference and underling Mafia members, suggesting generalization of boss/underling relationships."
For the model to recognize these types of relationships, the authors would have had to explicitly tag these agents as possessing either these qualities the constituent elements of these qualities. In either case, it's easy to imagine post-hoc biases in the model's "memory encoder" that generate just-so results without actually reflecting the biological or theoretical underpinnings.
How these relationships are assessed by the "memory encoder" and the "story parser" has much to do with the way features are associated with lexemes. From http://nn.cs.utexas.edu/?miikkulainen:phd [utexas.edu]:
"Processing in DISCERN is based on hierarchically-organized backpropagation modules, communicating through a central lexicon of word representations. The lexicon is a double feature map, which transforms the orthographic word symbol into its semantic representation and vice versa."`
(http://neuroskeptic.blogspot.com/2011/04/schizophrenic-computer.html)
A judgement of this article depends largely on whether the parser assigns meaning with a result (at the very least, or, given that the goal is to model schizophrenia, in a way) that's compatible with the output (or processes) of human linguistic cognition.

Re:REALITY: SCHIZOPHRENIA REDUCES MEMORY (Score:3)
I don't think that they're saying that episodic memory improves from hyper-learning. A 'normal' brain throws out most of the information it receives in the process of highlighting the important, useful information that's incident on the brain's circuitry. Because of this ability, the brain is able to create a coherent narrative for itself.
The scientists are saying that, in schizophrenic brains, what ends up being remembered is not this useful information. Instead, the wrong information is selected by the neural circuits such that the wrong information ends up encoded in long-term memory. This information is selected as being just as important, or even more important, in the episodic 'story' than practical information, such as, for example, the reminders that you point out they forget. The end result is that the long-term memories end up being incoherent.
So it's an issue of hyper-learning everything, not just what's important. If it was simply increased salience for what was important, that would be usefully improved memory. Also, while the symptoms of schizophrenia that you point out are correct, those are the outward psychological symptoms. These scientists are exploring what happens neurologically, at the level of individual neurons.

The Negative Symptoms of Schizophrenia result in Apathy, Lack of Motivation, and General Disorganized Thinking. Those patients I know who have this illness DON'T remember many things. In fact, they require regular "reminders" of the things that they ought to remember. I think this Notion that people who have this Illness "never forget" is not founded in fact. There is no evidence to support this hypothesis or notion.
That needn't be a contradiction. It could be just the same as in the physical world: The more stuff you keep, the harder it gets to find the stuff you want. If there's nothing else on your table, the paper saying "don't forget to buy a birthday present for $SOMEONE" will stand out, and every time you look at the table, you'll be reminded of this. OTOH, if the table is full of different papers, you'll likely not notice that one with the important reminder on it. It's almost as if it weren't there.

One has negative symptoms because he is missing large portions of brain tissue and the other has positive symptoms because his intact brain is not working correctly.
