- jshooter1377, on 08/09/2008, -1/+12My brain is plotting against me, these blueprints might save my life.
- jec68, on 08/09/2008, -2/+11ahhhhhh... one step closer to the singularity...
- LeadStripes, on 08/09/2008, -0/+8Gee Brain, what do you want to do tonight?
- doshindude, on 08/09/2008, -0/+8That brain looks like it needs a defrag.
- cloudberries, on 08/09/2008, -0/+8Indeed. It's not like such a system has had the opportunity to go through billions of revisions, with thousands and thousands of seperate test cases in each instance what with the world being only 6000 years old and all that.
- junkwheel, on 08/09/2008, -0/+7My brain is impressed.
- Atomic05, on 08/09/2008, -0/+6No, whats really funny is that people still invoke a god to explain what they don't understand.
- zadadka, on 08/09/2008, -1/+7Same thing we do every night Pinky.....try to re-invent the wheel. ;)
- BurningSand, on 08/09/2008, -1/+5I wonder what that costs?!
- Kevin108, on 08/09/2008, -0/+4Did anybody else wonder who this Brian was and why he needed to be unmasked?
- shannobn, on 08/09/2008, -0/+3That is so beautiful. So complex.
- booUSA, on 08/09/2008, -1/+4http://www.technologyreview.com/Biotech/21175/page ...
are you ***** kidding me? the human brain is 25 times more complex than THAT?! - TopherT, on 08/09/2008, -0/+3Dyslectics of the world, untie!
- Metasquares, on 08/09/2008, -0/+3One thing the brain is VERY good at doing is compressing like a sponge without losing significant function (which is why meningiomas can grow so large without causing symptoms, for example). That millimeter of tissue might be rather neurally dense.
- Metasquares, on 08/09/2008, -0/+3I don't know why people are suddenly finding out about DTI *now*. It's been around since 1991.
- Torley, on 08/09/2008, -0/+3Every July, peas grow there.
- Niightwitch, on 08/09/2008, -0/+2Marmoset brains generally run about 7 dollars, for a fresh one.
- bipolarruledout, on 08/10/2008, -0/+2Would you prefer to distill someones life down a statistical measurement of dollars vs. risk?
Medical professionals and particularly doctors are not gods. People tend to have exaggerated expectations because we have proped these mortals up higher than should have ever been expected. An educated opinion is still just an opinion and I believe many medical professionals take on epic levels of phycological pressure because they are rarely allowed to be wrong. Unfortunately no person is perfect and that's just the way it is, it's best the recognise that and move on to more important maters like reforming our medical system so people don't have to deal with $40,000 bills. - bincoder, on 08/09/2008, -0/+2And still...
ER can't tell if its a stroke, alzheimers, or a simple dizzy spell when an elder gets delivered by ambulance...
But they will sure be certain to charge $40,000 to Not find out and take their sweet time in doing it. If your lucky, they will correctly guess the problem on the next coin toss. If not, you die after you've left ER when its not their problem anymore. - inactive, on 08/09/2008, -0/+2I was thinking the same thing! Looks like my server room!
- Metasquares, on 08/09/2008, -0/+2Sort of. You might be thinking of Godel's Theorem of Incompleteness, which (roughly) states that a mathematical system of sufficient power to count the natural numbers can contain propositions that can't be answered from within the system.
- Kyrgizion, on 08/09/2008, -0/+2Inb4 *****.
- flarn2006, on 08/09/2008, -0/+2It looks like it's already running!
- spaceman60, on 08/09/2008, -0/+2I think you are talking about fMRI. This is something else, a structural technique, where the guy in the scanner could be sleeping, awake, fantasizing whatever and it doesn't matter. It images micro-anatomy
- cloudberries, on 08/09/2008, -0/+1Can it play..? etc.
I wonder if a human brain is even capable of understanding itself fully, in all its detail. Is there any sort of law, or algorithm stating that a system of n complexity can only understand systems less complex than n? - inactive, on 08/09/2008, -0/+1I wouldn't count on it, there seems to be a lot of redundancy in neural structure. Take the case of the civil servant with Dandy Walker syndrome (can't find the original article, google it for more info); he lead a pretty normal life (albeit with an IQ of 74) even though he only had a millimeter or so of brain tissue left, stuck against his forehead.
- cloudberries, on 08/09/2008, -0/+1And even then, the true picture is at least 100 times more complex, since each line represents hundreds or thousands of individiual pathways
- arpnuke, on 08/09/2008, -0/+1I'd like to see the same scan done on someone tripping their face off on some good, clean LSD.
- itcoll, on 08/09/2008, -0/+1so much wirings in my brain ???? got to remove some of them ......
- Metasquares, on 08/09/2008, -0/+1I've heard neurologists call it "spaghetti" :)
- spaceman60, on 08/09/2008, -0/+1I actually remember seeing this guy a a conference. The cool thing about his work is he doesn't only make the pretty lines, he does the experiments in monkeys and then cuts up the brain to make sure that the lines are actually going to where they're supposed to go.
I know, killing monkeys, I don't like it any more than the next guy, and I probably wouldn't want to do it myself, but it's really important work. If he didn't go and compare the DSI results to brain meat, people would look at the pretty lines and say "nice picture, I don't buy it." Once verified in monkeys, people can use it in humans with some confindence. - spaceman60, on 08/09/2008, -0/+1research scanner time runs about 550/hr. I'm not sure but a good DSI data set should take about at least an hour. Oh and you have to be completely still the whole time
- MercyBuckets, on 08/09/2008, -1/+2lol I like the picture. Sort of looks like the "rat's nest" wiring I've got going on by my computer, except ALL those neural networks in the MRI might actually have a reason for being there.
- Scaryclouds, on 08/09/2008, -1/+2I find it humorous how creationist point to the eye as proof of God because it is too complex to had evolved (which is wrong), but they completely miss the boat by not pointing out the most complex in (known) nature, the human brain, or hell any mammalian brain.
- Culyt, on 08/09/2008, -0/+1Brain scanning technologies increase in ability exponentially like computing power does, for both invasive and passive. Fairly soon we will be able to scan the whole brain ☺
They have scanned and simulated a rats neo cortex already for the Blue Brain project, using an automated robotic arm that mapped the neuron synapses and poked them to get the electric state from them.
☢ - bipolarruledout, on 08/10/2008, -0/+1I worry about what could be interpreted as a defect vs. a normal albeit less common difference. We shouldn't ever forget the tierney of the majority because the world as we know it is shaped by the majority weather they are superior or not.
- TopherT, on 08/09/2008, -0/+1Won't make any difference, its just a structural scan.
- devilclown, on 08/09/2008, -0/+1This is amazing, think of the possibilities images like this can create such as a better understanding of brain related diseases and brain injuries.
- NanoStuff, on 08/09/2008, -0/+1Computers tend to do that to existing technologies, reinventing and reapplying. DTI may have been around for a while, but unless you were willing to hire a million people for a million years to interpret and sort the relevant information, only now have such things become possible. X-ray topography machines and MRIs of the 80s could have been made 100 times more powerful just by strapping a modern workstation machine to it. The limitation of science is no longer gathering information but interpreting it.
- bipolarruledout, on 08/10/2008, -0/+1LSD has been known to be a cognitive enhancer for some time, at least in sub-hallucination doses. The activity is most certainly visible during MRI and other scans but there is still significant debate on how to interpret this data.
- bipolarruledout, on 08/10/2008, -0/+1Could have used a more pragmatic headline.... but then that's usually the case.
- kd1s, on 08/10/2008, -0/+1The creationists miss a lot of things. Look at recent news that Russian Foxes have been selectively bread for docile characteristics and what they've now ended up with is foxes who act more like dogs, even down to the color patterns.
Then of course there's that little 37,000 generation cluster of cells where one generation evolved to metabolize the gel in vs. the glucose they were being fed.
And not for anything, with 6 Billion humans on the planet, don't you think little incremental bits of evolution are happening even to us?
That's the thing with creationists, they want to remain ignorant because learning from other sources is just too hard for them. - techmaster, on 08/09/2008, -0/+1Was anybody else hoping that this was a reference to the movie "Waiting"?
- M724, on 08/11/2008, -0/+1And yet... so many people don't use their brains.

- zadadka, on 08/09/2008, -1/+1Such a snapshot doesn't demonstrates functionality, it merely shows what was chemically occurring at that particular point in time in a given individual scenario, with given stimuli, and with pre-determined (pre-chosen would be more accurate) filters applied to the subject results.
You simply cannot apply universal rules to a subjective pattern of results, and even more so where a pattern is not determined.
This is as about as accurate as saying all children on a beach given a ball will play a specified game, notwithstanding all other quotiants.. -
