Very convenient. Also it does math for you, an' keeps books, an' acts as consultin' chemist, physicist, astronomer, an' tea-leaf reader, with a "Advice to the Lovelorn" thrown in.

            It appears that Leinster beat Asimov to the punch; it's possible, being a science fiction fan before he was a science fiction writer, that Asimov even read "Joe". Wikipedia puts "Joe" at 1946, but Multivac in 1955 [wikipedia.org].

      Maybe, although I personally find, as someone who has spent a considerable amount of time developing technical skill at drawing and painting, that the process of learning to draw has also considerably altered my aesthetic sensibilities. Drawing is ultimately not that much about knowing how to move your hand just right. In fact, it seems to me it is largely about forgetting about the hand, and concentrating on the form of what you are drawing instead... In any case, I doubt a direct mind-to-picture system would in itself be enough to make anyone an artist. Maybe to reproduce what a person sees in front of them, but to be able to make a picture without exact reference, you're still going to need to know very precisely what you want each detail to look like. I think even with this kind of tech there'd still be a pretty intense learning process involved.
      • I think a direct mind-picture system would constitute a new artistic medium, with it's own advantages and drawbacks. There would still be a learning curve, and traditional drawing/painting skills would no doubt assist the artist. You might also combine the forms to touchup the captured mental images using more traditional methods.

        Alternatively one might use it in the manner of a camera. Things would get most interesting when we learn to directly pipe these experiences into another person's mind...

        I have a memory from my childhood that I can almost recall at will, at almost any time. When I was 6, my father took me on a week long canoeing trip. I remember standing on a road, looking through some trees down to the river onto some cool rapids which we were about to go down. I can see in my mind what seems to be a perfect picture: the side of the road, the wooded slope covered with dry leaves, trees, and the river. It seems that I could just sit down a draw the scene from my memory. The funny thing is, every time I try to focus on some detail, for example when try to identify the trees, or look at a number on a mile-post next to the road, or something like that, the whole picture completely disappears, and I have hard time recalling it again. The details are simply not there at all.

        Now if I were to draw the scene, I would undoubtedly substitute some sort of simplified shapes, or maybe just a pattern of shades of green, for the leaves. But you could look at the details of the drawing and see how it was done. You probably would be unable to identify the trees by their leaves, the drawing would not contain that much details, but you would be able to see the way the image is rendered on paper. I cannot do that with the mental image. I believe that in my mind I am able to render the overall image without actually rendering the details at all, not even as some sort of impressionist jumble of colors and shades. If that's the case, transferring this image onto paper would require filling in all the details in some way, which, IMHO, is exactly the hard part of drawing or painting.

      Images you acquire optically follow a very different path from dreams or "mind pictures".

    The visual cortex is one of the more understood areas of the brain, and decoding V1/V2 is low-hanging fruit. To the extent that memory and dreams back-project to these areas, perhaps recording parts of these experiences would be possible.

    Making this practical and inexpensive would be quite a practical breakthrough though - imagine being able to imagine something and import it into GIMP from a headband. Doing this through MRI would be impractical unless someone would be able to keep the image stable in their head for long enough for a high resolution scan of the area (and bear the ~$700/hour cost of MRI).

        The visual cortex is fairly well understood from electrical, fMRI and optical studies in animals.

      Can we "keep images in our heads" at all? When I try to, it is more of a feeling than an image, and it's a fragmentary one at that. Wouldn't it make sense if our imagination worked a lot like our vision, i.e. we can only focus on small bits of the visual field at once, and so would only be able to imagine those pieces and attributes of an image pertinent to our needs or wants?

      I'm free-balling here, mind. I can't seem to put coherent, complete images in my head, but others very well might.

        I'd mod you up if I could. It doesn't seem to me that when I imagine something in my head, there is actually a picture being made somewhere in my brain. It's an impression, a sense of shapes, something very fluid and ephemeral. I can, in a way, turn around three-dimensional objects "in my head", but the experience is far from looking at a video of an object turning. A simple dumb read of that kind of thing would probably be very difficult, although a person could perhaps train themselves to solidify their ideas into image form via a neural interface, much as they can ordinarily do with pen and paper, for example.

      Low-hanging fruit? I agree, it's fairly well understood, but given the pre-processing that happens in the retinal ganglion cells, and the kind of data that actually ends up getting to V1 (after being relayed from the LGN), I'm surprised an actual image can be reconstructed from the information. After all, the RGCs tend to pass on things like movement, edges, contrast and color, but it's not even remotely pixel by pixel type data, which is precisely the informaiton that gets passed on to V1.

      Since it's coming from an fMRI, there's no way the image can be very detailed. I suspect it will be very low resolution.

      Would looking at the image your brain is generating at the same time you are generating it create a feedback loop much like holding a microphone too close to a speaker?

    From what I can gather, they're pulling in rather low-level data - essentially 'listening in' on the very lowest level of pattern-recognition that's applied to the data coming in from the optic nerve. That's certainly interesting, but a whole lot more processing happens at higher levels before you 'see' anything. (C.f. people who lose sight early on due to eye problems, and have sight restored later - their brains can't do much with the information at first [newschool.edu].)

    Dreams appear to be based on the 'noise' coming in, but a lot of interpretation is applied (and without imposed constraints of consistency or logic). A common game/prank [ultimatecampresource.com] involves people asking yes/no questions about an alleged dream, but the answers they get are based on some simple scheme like "yes if the last word in the question they ask ends in a consonant". Surprisingly detailed 'stories' get constructed... by the person asking the questions. (Here's what appears to be an online version [callenish.com].) Actual dreams seem to be built in an analogous way, with the subconscious 'asking questions' of the senses (which are just feeding in 'static') and weaving an experience out of them.

    I'd guess that 'eavesdropping' on dreams via this means would only get the kind of swirling colors and such you 'see' when you close your eyes.

  • Just wondering what the Department of Homeland Security would do with technology like this. Its kind of scary, don't you think? Especially if this gets optimized and is proven accurate. On the other hand, imagine being able to reconstruct exact images from the mind of a victim to identify their assailant? But then you still have an issue with accuracy because human memory is so prone to being influenced. Still, pretty neat stuff.

    The primary visual cortex (V1) has already been shown to be retinotopic. What's being seen can be mapped directly from the cortex. It's crude and low-res, but it works.

    20 years ago a researcher working with Karl Pribram at Radford University was able to detect signals from small cellular assemblies of the visual cortex that represented a particular shape being viewed without mapping the entire shape from V1.

    In both these, the images were received directly from the brain. In both they were digitally processed and presented. In all three what was retrieved was not an image, but was a pattern of neural electrical activity that they had already determined represented a particular visual field. They could not (in keeping with the /. tendency to represent reality with fiction) for instance, retrieve the third frame of a series of images that had been briefly presesnted. They would have had to show the image for some time that record EEG from the appropriate areas for long enough that they could get a good correlation when showing it a second time.

    If scientists can understand perfectly how the brain translates images into neural signals, it opens up the possibility to build full cybernetic eye replacements, even if the nerve tissue is damaged and non-functional. The medical applications are mind-boggling.

    Also, I'm reminded of the interrogation device from the movie Barb Wire, the one that pulls out images from your brain whether you want it to or not...

    I think this would be amazing for law enforcement sketches. Instead of having to ask a witness what the person looked like, they could just copy it out of their visual cortex. No, it wouldn't be perfect, and it wouldn't be acceptable in court as proof someone was there (since you can just imagine your worst enemy in the place of the actual person), but it would help with sketches for wanted posters and the like. Especially if it was cheap and easy.

    I wonder if the process can be reversed, and images can be fed into the brain to create a dream sequence? Will people who really hate their reality use this as an escape and never try to wake up again?

    Cool story!

  • Didn't they do something like this on Fox's Fringe [fox.com] series as a plot device?

    For anyone unfamiliar with the show, it's basically Fox's response to Eureka on the SciFi channel, only much, much darker and probably unlikely to last more than one season...

  • I always wondered how the President of the USA could end up with his brain missing but mostly why it could be missing. I figured the Sci-Fi stories of brain scanning and the likes probably had someone worried something in JFK's memory should stay hidden unknown to all others.

    now it seems that if this was the case, they just might have based their actions on a valid fear.
