Elon Musk Unveils Neuralink's Plans For Brain-Reading 'Threads' and a Robot To Insert Them (theverge.com) 201

Neuralink, the secretive company developing brain-machine interfaces, held a press conference today where it unveiled some of the technology it's been developing to the public for the first time. The first big advance is flexible "threads," which are less likely to damage the brain than the materials currently used in brain-machine interfaces and create the possibility of transferring a higher volume of data.

"The threads are 4 to 6 micrometers in width, which makes them considerably thinner than a human hair," reports The Verge. The other big advance that Neuralink unveiled is a machine that automatically embeds the threads into the brain. From the report: In the future, scientists from Neuralink hope to use a laser beam to get through the skull, rather than drilling holes, they said in interviews with The New York Times. Early experiments will be done with neuroscientists at Stanford University, according to that report. The company aims for human trials as soon as the second quarter of next year, according to The New York Times. The system presented today, if it's functional, may be a substantial advance over older technology. BrainGate relied on the Utah Array, a series of stiff needles that allows for up to 128 electrode channels. Not only is that fewer channels than Neuralink is promising -- meaning less data from the brain is being picked up -- it's also stiffer than Neuralink's threads. That's a problem for long-term functionality: the brain shifts in the skull but the needles of the array don't, leading to damage. The thin polymers Neuralink is using may solve that problem.

However, Neuralink's technology is more difficult to implant than the Utah Array, precisely because it's so flexible. To combat that problem, the company has developed "a neurosurgical robot capable of inserting six threads (192 electrodes) per minute [automatically]," according to the white paper. In photos, it looks something like a cross between a microscope and a sewing machine. It also avoids blood vessels, which may lead to less of an inflammatory response in the brain, the paper says. Finally, the paper says that Neuralink has developed a custom chip that is better able to read, clean up, and amplify signals from the brain. Right now, it can only transmit data via a wired connection (it uses USB-C), but ultimately the goal is to create a system than can work wirelessly.
Currently, the company is testing the robot and threads on rats, but it's hoping to actually begin working with human test subjects as early as next year.

      Why didn't they use the Borg icon I haven't seen in a while on /.

    • They had a great website but they disappeared when they didn't get enough funding.

      That sums up many, many startups. The website generally is their best feature.

    First, hello Slashdot. It's been quite some time since I last logged in. Greets and all that jazz.

    This flexible polymer with seeking type robot just oozed a comment. Elon is definitely out to see some future happen in his lifetime. I am a fan, just because he's perfectly willing to take the big risks and see what can be done. Works his ass off too.

    Not for everyone, but while we've got him. Thanks! Let's hope for some goodness.

    In my mind, there are two things:

    One, any kind of two way interface. Yeah, there will be risks, but it's like having an extra channel. I suspect just getting it in there and figuring out how to setup the feedback loop needed for a person to be aware of it and explore is the hard part. Once they do? Look out. Pretty soon, talking to someone may not be any assurance you are talking just to them. They may be consulting all sorts of information resources, even just acting. Crazy times ahead. File all the obvious enhancements under this heading. Speculate away!

    The other thing is fixing broken people. Seems like amazing possibilities here. That's exciting, if nothing else.

      While this may all seem like sci-fi WTF right now, I lived over 20 years before cell phones became common and I hardly remember a world where you couldn't find nearly any information with a 2 minute search on a device you carry everywhere. In another 30 years my kids might not remember a world where you couldn't find nearly any information with a 200 microsecond search performed by your thoughts and aided by an AI which makes today's Google seem quaint.

      • Plus my first computer only had 64k and my current one has 16GB. Thus we will be living on Mars soon.

      • Seems reasonable, especially when you consider that the MOSFET [wikipedia.org] was invented only sixty years ago. Not even one human lifespan.

        Unfortunately technology seems to develop faster that society can properly cope with it. If technology can be weaponized, it will be.

      Yeah thanks! Not only does he himself create the idea of electric cars, space(!) rockets(!!) that can be reused(!!!), electronic money, brain-computer interfaces but he also protects 30 year old children against demonic pedophiles!!!

      So he have money to spend (mostly the money of others), likes to take risks and then push the idea he himself is a creative genius. Nice if something useful comes out of it but no reason to idolize a pretty disgusting human being.

  • A book I read about neuroplasticity suggested that the brain can learn to process new electrical signals and that's something like how the cochlear implant works. I'm looking forward to being networked but I won't be volunteering for the first human trials.

    I watched the whole livestream. The current version uses ~1000 electrodes, and they're expecting a version that uses 10k by the time they start human trials; it was aspirational that they'd have FDA approval and human trials starting late next year, so 2Q20 sounds like Elon-time.
    Each electrode supposedly produces 200Mbps of data, which is filtered and compressed; although I suspect the speaker misspoke given he said it was 20kHz sampling at 10-bit resolution, which would be 200kilobits/sec. The electrodes can read or write data; that is, they can also trigger nearby neurons.

    The wireless version will use an induction coil, with the implanted chip only being activated when a combination battery/computation device is placed on the skin which gives power inductively, and also computes transmitted data, although Bluetooth will also be utilized for phone connectivity. Something that was repeatedly emphasized is that this N1 device (their first commercial version) will be implantable in an outpatient procedure in an office, comparable to Lasik surgery, with the robot working automatically and programmed by someone trained to use it rather than a neurosurgeon using e.g. a Da Vinci surgical robot; and that the device is designed to be used continuously everywhere, like a prosthetic, not just for a session at a clinic.

    Elon also let slip that they've already done trials with monkeys, allowing one to control a computer with its mind. They're apparently going to start trials with quadriplegics, to control mobile devices & computers. Later they'll try applications to help those with Parkinson's, dementia, depression, and other neurological disorders. One possibility that was raised is the ability to simulate the sensation of touch (haptics), which could be combined with reading motor intent to allow for virtual limbs. Controlling computer avatars was specifically mentioned, which I reckon could eventually lead to full-dive VR systems. Artificial visual sensations were also mentioned, although this seemed further out; this could be used to help blind people see, although it could also replace screens if computers could directly tap into our visual systems. Speech can apparently be synthesized from motor intent, allowing for the mute to speak (or for people to 'speak' without making a sound.)

    The sci-fi applications were mostly glossed over, as this presentation was a broad overview of everything. The implication is that they're creating a platform which will be capable of more and more things as time goes on and the tech and neuroscience improve. It's pretty amazing what they've achieved in just over 2 years, and I'm pretty excited over what they might be enabling two more years from now.

    • I have no idea why this was the thought process going through my mind as I read your comment (good comment by the way):

      Everyone will be implanted with a version of this at birth. The version I am speaking of has the ability to "read your mind" and "paralyze" you when someone (police) with a particular device is nearby and presses a button.

      Got a bar fight with a bunch of bikers going on? No problem. Send one officer in with the "device" and he pushes the button and everyone falls to the floor no longer in co

      • Steady on Charlie Brooker.

  • We live in a world where it's all but certain that technology like this, if successful, will be misused by governments and corporations to spy on and control people. For that reason I'd just as soon we didn't have technology like this at all. Perhaps, if we manage to 'grow up' past the need for power-grubbing, we can have Nice Things like this potentially promises, but as we currently are, as a species, we just can't be trusted with it.

    • You have to train your neural net to use stuff like this, the weird scifi stuff won't be until whenever someone in China runs this through a newborn (maybe a CRISPR one just for fun) that grows their whole net from scratch around being able to utilize tech like this to interface with machines. Which now that I think about it, would be a good way to get AI level superpowers without having to figure out how to build an AI... funny to think it might be easier in vitro than in silico.

    Yeah, because that's what I've always wanted, a direct neural interface that can be wirelessly hacked by any asshole that wants to fuck with my brain.

    There is also potential for abuse. For example, if we can understand exact data path and processing algorithm for visual cortex, it might be possible to develop exploits (and weaponize them).
