So, the beats you're hearing are real time signals from the neural link in Gertrude's head.
So this neural link connects to neurons that are in her snout.
So, whenever she shuffles around and touches something with her snout, that sends out neural spikes which are detected here.
Welcome to the neuro link product demo.
Really excited to show you what we've got.
I think it's gonna blow your mind.
So when I emphasize the, the purpose of your link like what, what do we What's our goal?
Our goal is to solve Important spine and brain problems with a seamlessly seamlessly implant implanted device.
So, you wouldn't have a device that you can basically put in your head and feel and look totally normal, but it solves some important problem in your brain or spine.
So, going into the neural link architecture What we've done over the past year is dramatically simplify the device.
So about a year ago we had a device which had multiple parts including a piece that had to sort of sit behind your ear.
And it was complex and You wouldn't still look totally normal, you'd have a thing behind your ear.
So we've simplified this to simply something that is about the size of a large coin and it goes in your skull replaces a piece of skull.
And the wires, then connect within a few centimeters or about an inch away from the device.
And this is sort of what it looks like.
It was a little device.
That thing at the bottom is just to hold the threads in place cuz they're just like little fine wires.
Frankly, to sort of simplify this, what we're It's more complex than this, but it's, in a lot of ways, it's kinda a fitbit in your skull with tiny wires.
Our current prototype version of 0.9 has about 1000 channels.
So that's about 100 times better than the next best consumer device that's available.
And it's a 23mm��8mm.
It actually fits quite nicely in your scalp.
Just your skull is about 10 millimeters thick.
So it goes flush with your skull, it's invisible, and all you can see afterwards is that tiny scar, and if it's under your hair, you can't see it at all.
In fact, I could have a neural link right now and you wouldn't know.
All right, so it's also inductively charged so it's charged.
And the same way that you charge you charge a smartwatch for a phone.
And so you can use it all day, charge it at night and have full functionality.
So you would really yeah, it would be it would be completely seamless.
And yeah, no wires in terms of getting a link.
You need to have the device, a great device and you also need to have a great robot that puts in the, the electrodes and does the surgery.
So you want the surgery to be as automated as possible and the only way you can achieve the level of precision that's needed is with an advanced robot.
The link procedure the installation of a link Done in under an hour.
So you can basically go in in the morning and leave the hospital in the afternoon and it can be done without general anesthesia.
So, this is a surgical robot,
And we actually ultimately want this robot to do Essentially the entire surgery.
So in everything from incision, removing the skull, inserting electrodes, placing the device and then closing things up and having you ready to leave so we want to have a fully automated system.
So this this shows you sort of close up view I think it's actually not too gruesome of the electrodes being inserted in the brain.
And if you look closely, you'll see that it's a little counterintuitive that if the electrodes are inserted very carefully, that there is no leading and so the If you have very tiny electrodes, and if they're inserted very carefully so that the robot actually images the brain and make sure to avoid any veins or arteries, so that the electrodes can be inserted with no noticeable damage, so you will have no noticeable neural damage in inserting link So does it actually work?
And what I'm excited to show you a quote like the three little pigs demo.
And if I don't have this variant, we're bringing out the pigs and we're going to show you is a Well, I'll walk right over and show you.
So all we have in pen number one is Joyce and she does not have an implant.
Obviously healthy and happy.
[LAUGH] We're trying to get Gertrude out.
And this is how you know it's a live demo.
Here's Dorothy and in the case of Dorothy, Dorothy used to have an implant and then we remove the implant.
So this is an a very important thing to demonstrate is reversibility.
So if you if you have in your link, and then you decide you don't want it or you want to get an upgrade And the neural link is removed isn't removed in such a way that you are still healthy and happy afterwards.
And what Dorothy illustrates is that you can put in the neural link, remove it and be healthy, happy and indistinguishable from an old pig.
Now, thanks to Rz [LAUGH] Here we go great.
[SOUND] This is a high energy pig.
All right, Gertrude, thanks for coming out.
So the beats you're hearing are real time signals from the neural link in Gertrude's head.
So, this neural link
Connects to neurons that are in her snout.
So whenever she snuffles around and touches something with her snout.
That sends out neural spikes, which are detected here.
And so on the screen, you can see each of the spikes from the 1024 electrodes.
And and then if you if she shuffles around touches us out in the ground, or you kind of Peter some pigs look and you can see the neurons will fire much more than when you're not touching this now and that's what's making the beeping sound All right, cool.
So as you can see, we have healthy and happy pig [SOUND] Initially shy but obviously high energy and and kind of loving life and she's had the implant for two months.
So this is a healthy and happy pig with a plant that a two months old and working well.
All right, cool.
And then we actually have this works is.
So we said, well, what if we do two neural link implants and we've been able to do Dual neural link implants in actually, I think three pigs this point, and we have a couple of them here.
And we're able to show that you can actually have multiple neural links implanted and again, healthy and happy and indistinguishable from a normal pig.
So it's possible to have multiple links in your head and have them we'll be sending out signals and you're working well.
All right, so we just showed you a demonstration of reading brain activity and see posting that.
And the blue chart at the bottom is showing an accumulation of neural spikes in that region.
So, in terms of additional brain reading activity, when we have said what about pigs on a treadmill Pig on a treadmill, [LAUGH].
Funny concept really.
And we take the readings from the neurons and we try to predict the position of the joints.
And so we have the predicted position of the joints and then we measure the actual position of the joints.
You can see that they're almost exactly aligned.
So we're able with a wireless neural neural implant to actually predict the position of all of the limbs in the pig's body with with very high accuracy.
Now in terms of writing to the brain or stem stimulating neurons We also need precise control of the electric field and in space and time, we need a wide range of current for different brain regions.
Some regions require delicate stimulation, some require a lot of current, and you want obviously no harm to the brain over time.And the way we apply the way we analyzed the The stimulating neurons is with a two photon microscopy, I always have trouble pronouncing that microscope.
And it's very impressive technology you can actually literally see in real time how the neurons are firing.
So The red sort of things are the neurons.
Red sort of flashing things are the neurons, firing or I should say the electrodes firing.
So, the red things are electrodes firing, and then the green are the neuron body's responding to the current from the electrode.
And we're making good progress towards clinical studies.
I'm excited to announce that we received a breakthrough device designation from the FDA in July, thanks to the hard work of the neuro link team.
[APPLAUSE] So I want to be clear, we're working closely with the FDA.
And we'll, be extremely rigorous.
In fact, we will, significantly, exceed the minimum FDA guidelines for safety we will make this as safe as possible.
But what are some likely first applications?
So our first clinical trial is aimed at people with paraplegia, or tetraplegia.
So, cervical spinal cord injury.
We're planned to enroll a small number of patients to make sure the device is safe, and that it works in that case.
Yeah, so actually just to elaborate on that, if somebody has like a severe spinal cord injury, you have to agree that they have very limited control even over their facial muscles.
I think something that's very exciting as a long term application is, if you can sense what somebody is trying to do, what their limbs what they want to do with their limbs.
Then you can actually do a second implant that's at the base of the spine, or wherever, just after wherever the spinal injury occurred.
And you can you can create a neural shunt.
So we I think long term, I'm confident that long term, it will be possible to restore somebody's full body motion.>> Another question from Twitter Will you be able to save and replay memories in the future.
Yes, I think in the future you will be able to save and replay memories.
And this is obviously sounding increasingly like a Black Mirror episode.
But well, I guess they're pretty good at predicting.
But yeah it's actually if you have a whole interface, I mean that's encoded in memory.
You could upload, you could basically store your memories as a backup and restore the memories.
And ultimately you could potentially download them into a new body or into a robot body.
The future is gonna be weird.
One common theme that's been coming up a lot on these Twitter questions coming in is that of availability and so Mateus has a specific question on this which is any estimate of how much it will cost at launch and what price it will reduce to over time.
I think at launch, it's probably gonna be I would say that's not really representative.
Cuz at first I think it's gonna be quite expensive, but that price will very rapidly drop.
And I think over time, we wanna get the the cost, obviously down as low as possible.
But I think, Inclusive of the automated surgery I think we want to get the price down to a few thousand dollars something like that.
And I think that's possible I think it should be possible to get it similar to LASIK and and then the device electronics itself I think will will not be very expensive Because it actually does does use a lot of the parts that are made in extremely high volume in 10s of millions of units for smartphones as well as smartwatches and wearables in general.
