LIFT08: Kevin Warwick, the "Cyborg" [en]

*steph-note: live blogged notes, may be incomplete, etc. Kevin is exploring where the machine starts and the human stops.*

Two things:

– chips in humans
– rat brains in robots

LIFT08 139

Working with Parkinson’s disease — deep brain scans to try to detect the illness before the tremors begin.

Research partly to help people, partly for enhancement. Eg. man who lost his arm to cancer, and has a robotic hand, but must use his exiting hand to control the robot arm. A bit silly! Would be better if he could control it directly — that would require an interface between the arm and the brain/neural system.

Increase sensory range.

Kevin has a chip with 100 electrodes implanted (fired!) in the nervous system of his left arm. 4mm in diameter.

*steph-note: wondering if that hurt?*

For three months had his nervous system partly out of his body. (Had to be careful to not short-circuit it when taking a shower). Part of this was to experiment stuff to help people with disabilities.

*steph-note: not sure I quite understood what the thing sticking out of his arm was — something to link him to the computer — and also if the chip was removed after three months or not.*

When Kevin was connected to the internet, if you had known the IP address of his nervous system… But what they did is not tell anybody what they were doing until they had done it. Careful not to get your nervous system spammed or hacked!

Highlights from the experiment. Output from the sensors fed to his nervous system (fancy thing on his wrist).

When an object came closer, his brain received and increased frequency of ultrasounds (?). So basically with a blindfold on, Kevin was able to move around and detect objects pretty accurately. Not what they were, but where they were.

“It felt like something was coming close to me.” Extended the sensory range. Like “what does it feel like to see something”?

*steph-note: showing a short video clip. It makes Kevin sound like Terminator! Will add link if somebody gives it to me.*

Experiment with his wife: when his wife moved her hand, he felt it. He could actually feel her movements.

*steph-note: Daleks in the video!!! I find it hilarious — the angle this video takes.*

Jewellery his wife wears, and the colour changes with his excitement: blue, calm, flashing red: excited. “What is he doing? and with who!?”

Through the internet, made a robot hand mimic what his hand did, with feedback. Objective: hold an object. Good news for people who have been amputated. But also, stretching Kevin’s body across the Atlantic.

His wife had wires pushed into her nervous system from the outside. Very painful! But no anesthetic, because the doctor said he needed to see if he made good contact. It hurt!!

Linked their nervous systems. When she moved her hand, his brain received pulses. Worked very well. Vice-versa: “like lightening running through her hand” when Kevin moved his.

Kevin’s research is now moving from nervous system to the brain directly. Brain to brain communication! Telepathy. Ideas, codes, concepts, images. Upgrade these humans. Communicate in a respectable way!


The implant was taken out because the wires coming out were starting to break, it was an experiment — a lot of practicalities.

Kevin’s experiment changed the way people look at things medically. “Cyborg” is not anymore a purely SF term.

Lots of things could have gone wrong with the experiment, but as a scientist, it was tremendously exciting! Discovered stuff about the nervous system that nobody knew, because nobody had done this before. Scary but really exciting. Rollercoaster.

It took Kevin’s brain six weeks to recognize the electric pulses it was receiving as a “distance radar”. Boring time, but it took that time to train his brain, and it adapted — he actually “felt” how far things were.

What next? Research on Parkinson’s, by analysing deep brain scans to predict tremors. Also with epileptic patients to try to see when the fit is coming. Parkinson’s: can predict tremors 15-20 seconds before they happen! With epilepsy, 25-30 **minutes**! *steph-note: wow.* This can change the patient’s lives!

Cultured brains. After a week, a rat’s brain starts having some “neural firing” (activity), and after a month it’s starting to act like a brain. All the brain knows is that it drives the robot. Not good drivers! Now, trying to teach these biological brains how to drive the robot better. Lots of philosophical questions. *steph-note: so, from what I understand, they don’t remove brains from rats, but grow them.* Cultured neural networks. Artificial intelligence. *steph-note: Cylons!*
