What's it like to live as a cyborg?
Kevin Warwick, Cybernetics Professor at Reading University has delvedg deep into his nervous system to become one of the world's first cyborgs. We find out more.....
Kevin - Well, I've had a number of implants. The most successful one from it consisted of 100 electrodes, very small spikes which were fired into the nervous system in my left arm to link my nervous system with a computer and then on to the internet. So essentially, we're using neural signals that are signalled from my brain to control the robot hand in various places of technology. But also, to feed signals back from a computer into my nervous system, so I could so I could experience the extrasensory input, learn to recognise ultrasonic signals for example and recognise distance to objects, and so on. It was really looking at extending the abilities of a human by using implant technologies, implant technologies of that kind.
Hannah - What were your own reasons for wanting to become one of the world's first cyborgs?
Kevin - Well, it was two-fold. One was to look at the technology and assess it for looking at helping people who have problems for therapeutic purpose - people who are paralysed or people who are blind. All sorts of different cases where the person's brain is functioning perfectly okay, but there is a problem getting signals from the brain to the outside world for them to move or operate technology, or whatever happens to be, or getting signals into the brain. It was really in a general way, how could people like that be helped. But at the same time, the second aspect was just, "Okay, well if we're linking directly to the brain then we're no longer restricted by the physical input/output that humans have - the human body such as the eyes and ears, or hands and legs to move. If you connect directly to the brain then you can connect with all sorts of other pieces of technology and so, the person can have lots of different extra abilities - different senses and control different things from their brain directly. So, it was looking at the enhancement side, allowing people to have extra abilities, as well as just using the same technology for therapeutic purposes.
Hannah - What kind of implications for society do you think that this technology has?
Kevin - First point is, I think we can and we'll see over the next 10 years, all sorts of different neurological problems that will be tackled by using technology of this type. So, things that at the moment, we couldn't imagine and then maybe chemicals, pharmaceuticals are the best we got. So, things like Schizophrenia for example, I think that it's going to be tackled by using this technology. Deep brain stimulation is available now to successfully tackle Parkinson's disease for example and it's also being used for things like Turret Syndrome, epilepsy. So, these are electrodes deep in the brain that can counteract the effects of a particular problem. Schizophrenia is amongst the problems - it's a much broader problem, but it's one of the problems that are now being looked at and initial investigations are being made as to where exactly to apply electrical currents to overcome the problems where to stimulate. I think partly, it's opening up more of an understanding on the problem, but also, with the possibility of actually tackling the problem itself.
Hannah - What do you think was the - from your experiment on yourself - had the most impact on your life in terms of the kind of extra skill that you gave yourself?
Kevin - The biggest thing for me, my wife also had electrodes implanted and we'd send signals from brain to brain, literally communicating electronically directly. I think in the future, that's going to be the biggest thing of using technology into the brain that we will be able to send signals to communicate directly from brain to brain, between humans, humans and machines, and so on. Therefore, this form of communication we call speech which is pretty pathetic technically, will be obsolete before long. We'll communicate just by thinking to each other.
Hannah - What did you communicate with each other?
Kevin - For us, it was a very, very basic thing. A bit like, if you can remember the Morse code and telegraph type signalling dots and dashes. When my wife closed her hand, my brain received an electronic pulse. So, she throws down 3 or 4 times, "dic, dic, dic, dic" like that, my brain receives several pulses. So, it was very much the first basic type of communication. But when we have a much broader connection directly from brain to brain then clearly, it will open up all sorts of communicating in terms of thoughts, images, feelings, emotions a much broader range of communication than we have at present.
Hannah - Thanks to you, Kevin Warwick who started cyborg communications with his wife back in 2002.
