We're living in momentous times. Now, I don't know whether you know but this is a world first -- the TED conferences go all over the world, all different countries -- this is the very very first time -- normally you take a place name, normally you take a university name -- this is the very first time a TED has ever been named after a person and -- (Laughter) (Applause) I just wanted to say, it's a fantastic honour. We mentioned before Sheldon, and I just want to say there's never yet been a TEDxCooper so, Sheldon Cooper, eat your heart out. What we're gonna be looking at today -- yeah, plugging your brains into a network, what's the possibility both from a healthcare point of view and in terms of -- maybe some of you feel quite bored being a human, quite limited in what you can do and particularly your brain doesn't perform how it should, so, what are the possibilities of an upgrade. We should start tho, on the back of healthcare but as we gonna see it's a lot more than that -- implants and things like that. Class II sounds quite technical. In fact, what the Class II implants is for those of you that don't know -- This is a younger version of me, way back, the last millenium and my G. P. so this is was all done in the National Health. And what I'm having implanted is this little device -- not the thing on the left hand side. (Laughter) This is this quaint currency we still have. The thing on the right hand side -- a radiofrequency identification device. I had this implanted, because various people, Peter Cochrane, who's a head of B. T. research labs was saying, "In the future we are not gonna need passports, we are not gonna need credit cards -- What we will have is a little implant under the skin." But nobody had actually tried it until this particular experiment. Now what it did for me was, in my doorways -- I'm from Reading University. Is there anybody else here from Reading? Audience: Yeah! Kevin Warwick: Oh, come on! (Laughter) Anybody else here from Reading? (Clamor) Yay, there we go! It needed a bit of warming up there, I think. In my building, Cybernetic building at Reading, we've got coils of wire in the door frames. and if you have an implant of this type and you walk through the door frames then current is induced in the [implant], transmits a singal back to the coils, which are linked to the computer. And what it did for me was, as I walked down the corridor, the lights came on, just for me, walking to my laboratory, the door opened -- I mean, it's really cool stuff. Coming in the doors, says, "Hello, Professor Warwick." All fantastic stuff. And various people said, "Uh, who's ever gonna want to have anything like that?" No! Is anybody here got a cat or a dog with a chip implanted? It's all right, you can speak! Is anybody out there? You can rest assured, that this was fully tested on humans before your animal -- (Laughter) So no need to worry at all. There's actually a night club -- I know in the academic world we can't afford those things -- but, there's a night club in Barcelona, there's another one in Rotterdam, called the Baja Beach club, and if you go there they actually send you around the corner and you can get one of these things -- a smaller version, don't worry it's not that big -- implant it, and then when you go in the night club you don't have to pay for your drinks directly. It's automatically charged to your implant. I'm serious! Try it, try it. Good advert for the Baja Beach club. That's implant number 1. I'm going to flick on to "Regulation" because some of you may think this isn't going anywhere. Well, in the United States, they have, for people with diabetes and with epilepsy, they can have this thing implanted. And now, under Barack Obama, the healthcare rules that you have to have it regulated. Even with the possibility that you may have to have one implanted. We'll see where that goes. But I'm going to take you, right up to date, to what some of my students are doing. This is the sort of implant you could try yourself. This is Jawish, he's one of my students. I've got three students now, that have had magnets implanted in their fingertips for part of their degree courses that they are doing, my students. (Laughter) We have to get ethical approval from the university to do this sort of thing. And you may notice -- I'm supposed to stay on this red carpet but I'm going to zip up for a moment, 'cos you may notice here the guy who's doing the implant has tatoos on his arm. That's because he is a tatoo artist, that's what he does. And he goes by the name -- this is serious he goes by the name of "Dr. Evil". (Laughter) Now, we have to fill in a form for the university (Laughter) that says who is carrying out the medical procedure. Yeah. I mean, they can be really awkward over it, I have to say. This is an X-ray of Jawish's fingertips. You can see the magnets implanted. Now what we are doing -- now, on the baseball cap he's got ultrasonic sensors and the output from those sensors is fed down to a little coil of wire around the magnet. And what happens, as an object comes closer, the current in the coil is changed, so the magnet vibrates more the closer an object is, and less as the object is further away. So essentially Jawish can feel how far objects are away. So it's sensory substitution. Now, Ian Harrison, one of my PhD students with me now, he's linked up to an infrared sensor. So he has magnets implanted. Now, infrarred is like a heat signal. So what he can do is remotely feel how hot objects are. So if you can get the audience, you can point, "Ah, you are hotter than you, you are hotter --" (Laughter) I mean, in a temperature sense. Don't sort of stalk me or something like that, because I'm -- particularly the guys here, I really didn't mean it. (Laughter) But, you see, the military aplication for this is immediate. If you are a soldier and you are about to go into a room, and you don't know whether there's anybody there or not, you can simply push your finger around the corner and scan, "Ah! There's somebody over there!" You know exactly where they are, but also how hot they are, for what use that is. (Laughter) This is Ashley and he's doing some work -- a guy, Paul Bach-y-Rita, originally did this -- and it's actually sending little stimulating pulses into his tongue, to communicate in a new way. This is interesting, because people have never tried this before. If you actually tried it, very quickly you'd be able to pick up and pick up letters and signs -- So it's a new way of communicating. But the interesting thing is, if he sends a particular -- let's say, a triangle -- a particular shape, then the person even if they haven't tried it before, will say, "Yes, that's a triangle." But if we ask them to draw the triangle, then some people will draw it the right way up, some people draw it upside down and sideways, all sorts of different dimensions to it. We are not sure why. It is the routing from the tongue up to the brain is very very rapid and people can learn to use it to communicate very quickly. But there seems to be a particular way that it's wired that we have a lot to learn about. So it's one of those things with the research, you end with more questions than you started with. Now, some of you -- this is where if you want to go ahead with this, it could be dangerous for you now, but it might be something you want to do when you are technically dead. So, it's the sort of thing to put, not before, but as I die, could I try this, please. And that is, when you think of a robot, you think of either a computer-controlled device, or perhaps something that's remote-controlled. Well, what we are developing are robots with their own brains. And, what we do -- you see, on the right hand side of the picture here, is the physical robot. I mean, typically, because it is a laboratory and there we use a little robot on wheels. It has ultrasonic sensors. just like we saw on the baseball cap. But the brain of the robot is not a computer. The thing that says MEA is Multi-Electrode Array that's all right, you don't have to learn this. I'm not gonna test you on it later on. What does it say? (Laughter) About two people. Yes. All right. What is Multi-Electrode Array? What it actually is, is a little dish on the bottom of which are electrodes. What we do is take brain cells from rat embryos, separate them, and then squeeze them into this little dish, and grow them. We have to feed them using minerals and nutrients -- a little pink liquid that is amazingly expensive in comparison with Lucozade -- oh, advertising again I shouldn't say it. But it does roughly the same stuff. And they are kept in an incubator, at 37ºC That's where they grow. And then we link them up to a robot body. So the physical body of the robot is a technological body, but the brain is a biological brain that's growing. And what we are looking at, is trying to figure out particularly how memories appear in the brain. How it learns and adapts and so on and so forth. We can see -- witness it learning simple tasks at the present time. Importantly, at the moment, the rat brain robot, as it were, has about 100,000 brain cells. Where us humans have -- how many brain cells do we have? Audience: Six. Kevin Warwick: Six! This is a Manchester United supporter, obviously. (Laughter) (Applause) Don't clap on this stuff, isn't scientific! So, any advance on six? Audience: A billion. KW: A billion. I mean, it depends. Most of us have a hundred billion. I thought, "No, who counted this?" Americans say it's two hundred billion, but that's -- you know -- that's them, obviously. (Laughter) For the rest of us is a hundred billion. So we are talking here of 100,000. We're now growing these things -- this is the little dish on the left hand side. That's where they grow. We have to keep it moist and so on, it can't let it dehydrate. The right hand side are the electrodes, there you see. And the neurons grow in there, link up with each other. It's quite amazing, these brain cells! You put them down, they've got no connections. Within a few minutes you can see them putting out what look like tentacles. And these tentacles then start linking up -- You have to try this! Take a few of your brain cells out tonight, try and see -- They start linking up with each other very quickly to form the dendrites and the axons, the inputs and the outputs. And with just over a week gone, we've got this brain-like activity that we can use for the robot. And what we are using now, not just rat neurons but we are growing in three dimensions, which takes the number up to 30 million, and we are also using human neurons, because it links more closely to memories and things like that. So it's exciting research, and something you could do in the future, if you want. Deep Brain Stimulation is a medical process that's used to help people with Parkinson's Disease. You can see, it actually involves electrodes positioned in the central area of the brain. And what we are doing -- This is typically the sort of information that we have. The top line is the electrical activity in the brain as a patient -- this is from an actual patient -- experiences the sort of tremors that occur with Parkinson's Disease. So the bottom line is the muscular activity. And what we are trying to do is use artificial intelligence to learn to recognize the electrical activity so that, with the stimulators -- At the moment the battery only lasts about two years and it has to be replaced. We are trying to make the battery to last lot longer by making the stimulator intelligent, so it only stimulates when it needs to stimulate. So what the artificial intelligence system does is actually predict from the electrical activity when tremors are going to start, and then it stimulates just when it needs to. if you see what I mean. So it's to save the battery. Now the final area -- you may be all been waiting for this. Those of you that are already enhanced, probably would say, "Oh dear, we know all that." But there's other possibilities, if you thought, "Why should I bother with enhancement." I've just gone through them quickly. Memory, obviously, we forget all sorts of things. Communication is the big one, because, I'm sure anybody, all of us here, anybody [who] uses a computer is really embarrassed in how they have to communicate. Because, compared to technology, how we communicate is absolutely pathetic, isn't it, we have to admit. Highly complex electrochemical signals -- thoughts, images, concepts, emotions -- and when we want to communicate those to somebody else, what do we do we convert them into mechanical pressure waves. Oh dear -- And then (Laughter) those signals travel very slowly and somebody's ears will pick them up, convert these mechanical signals back into electrochemical signals -- What century are we living in here? (Laughter) The possibility of communicating directly from brain to brain -- we have to be working on that sort of thing so we can communicate not in terms of this simple coded messages but in terms of images and thoughts and emotions and feelings. Anybody that's been married now twenty, thirty years, you have no idea what it is your spouse is trying to tell you. If your brain was linked up you'd know exactly. If she's saying to you, "Yeah that's great, that's great." Now you'd actually know whether it's great, it's great. (Laughter) What I've done about this -- well this is the Radcliffe Hospital in Oxford. That's me on the operating table. This was two hours of neurosurgery to have this little thing implanted into my nervous system. It's called the Utah Array, because that's where it comes from --that's Utah, not Array. There's no place called Array. And it's got one hundred spikes on it. The electrodes [are] two micrometers -- they are very very small, but that's same sort of size as nerve fibers and brain cells, that sort of thing. And this was fired into the median nerves of my left arm and it was there for just over three months for the purpose of the experiment. Now, what could we do with it, in terms of the different experiments, 'cos partly was partly looking at, could we use this technology to help people who are paralyzed or have difficulties in that way. But also where could we go with enhancement. And we saw earlier, Jawish feeling ultrasonic signals, feeling distance. One of the things that I was able to do, was to feel distance, but this time more directly. It took me six weeks to learn to recognize pulses that we were inputting into my nervous system and when we did this experiment, as an object came closer, my brain was receiving pulses of current that increased in frequency the closer an object came and then decreased as the object moved further away. So with a blindfold on, I was able to detect objects and could detect pretty accurately if they moved closer or further away. This is my wife, Irina, who is with me today. She helped in a number of ways with the experiment the jewellry was put together by a student of the Royal College of Art. So you see, students can do useful things. (Laughter) Just, you know, take it as an inspiration. The jewellry changes color from red to blue. It was linked to my nervous system which I could, open and it's blue, close my hand and it's red. But if you can imagine now the best way -- If I'm calm and relaxed the jewellry is blue and if I get excited, the jewellry starts flashing red. Now she didn't work in the university and if you could imagine there, she's in her office and she's working around, and the jewellry is blue, "Fine, he's not doing anything he shouldn't,"and then (Laughter) it starts flashing red, "What is he doing?! And more importantly, who is he doing it with?" (Laughter) How she could be so suspicious, I don't know. This was taken at Columbia University, New York. And, if any of you have been there -- A film box here -- What film was filmed at Columbia University? Ah! Brilliant! Got it. Yes. Be louder. Audience: Ghostbusters. Kevin Warwick: Thank you very much, excellent. You win a Jamboree bag, ready for you are the back. Ghostbusters was filmed -- they also do research there. (Laughter) Sometimes. Sorry, Columbia. What we did was plug my nervous system live into the Internet, and linked up to a robohand which was back at Reading University in England. So when I moved my hand in New York, my brain signals went across the Internet to move the robohand. When it gripped an object signals were sent back across the Internet, so that I could feel how much force the robohand was applying on another continent. So one thing with this technology, you extend your body. Your brain and your body do not have to be in the same place. So, go for it. The final clip, which for me was the biggest thing This is my wife again, now what she had -- you can try this tonight, just push some electrodes into your nervous system. (Laughter) It goes by the name of "microneurography", so it sounds great. What it is, though -- is you will find it's extremely painful. (Laughter) We thought that she was going to have some anesthetic but the doctor said, "No no no, I need to make sure I made a good contact." So he pushed the electrode in, she screamed, and the doctor said, "Ah, I think we made a good contact there." (Laughter) We actually pushed two electrodes in, went back to the lab, and linked our nervous systems together electrically. So when she moved her hand, my brain received the pulse. So what we did was a telegraphic communication. She went, tick, tick, tick, and my brain received, tick, tick, tick. So it was a telegraphic communication directly nervous system to nervous system. That's what we actually achieved. Now where we go from here, clearly is brain to brain communication. Implants in one person's brain, another brain, and let's communicate in a much more effective way directly brain to brain. I have to say my wife Irina, for some reason feels that's a little bit dangerous, I'm not sure why. So presently I'm looking for a volunteer, so if there's anybody (Laughter) anybody there that doesn't mind having a brain implant and would like to communicate in a whole new way -- I know it's only my thoughts that you are gonna be receiving, but that's just the start. So I will leave you, thank you very much, and if any of you want to volunteer, please let me know. (Applause)
