Mayo clinic, right here in the good old USofA beat them to it by about two years, albiet accidentally. It had something to do with brain implants for people suffering from seizures, and somehow one of them figured out how they could use the implant to move a cursor on a screen. I don't remember the details. Someone else can look them up.

There are actually a number of projects in various places around the world to develop either "thinking caps" or ways to connect the human nervous system more perminantly to a computer.
Tomorrow is my day off, I'll bookmark this and round up some of the old links, I have been keeping track (or rather trying to keep track) of stuff like this on another website. |

Psh. They've been doing this for a long time. I worked on a project for a company that was doing this sort of stuff in 98-99, and I wasn't the first on the project. Although, they were using implants when I was working on it. www.neuralsignals.com |

The USAF can control a fighter with a rats brain in a petrie dish…
|
|
Well they finally did it!
Say goodbye to the polygraph tests of old... Welcome in the new info extractor! |
|
Uh no they cant. Its was not the USAF doing it; and its not a rat brain, its rat brain tissue; and its not a fighter but a video game of a fighter; and the purpose of the experiment was to to see how brain tissue reacted to having metal electrodes implatned into it, and how well nerve signals could be translated by electronics. |

Hahaha, that is ridiculous, I must see a link, man. |

Brain in a Dish Flies Plane By Jennifer Viegas, Discovery News Oct. 22, 2004 — A University of Florida scientist has created a living "brain" of cultured rat cells that now controls an F-22 fighter jet flight simulator. Scientists say the research could lead to tiny, brain-controlled prosthetic devices and unmanned airplanes flown by living computers. And if scientists can decipher the ground rules of how such neural networks function, the research also may result in novel computing systems that could tackle dangerous search-and-rescue jobs and perform bomb damage assessment without endangering humans. “ The end result is a neural network that can fly the plane to produce relatively stable straight and level flight. ” Additionally, the interaction of the cells within the lab-assembled brain also may allow scientists to better understand how the human brain works. The data may one day enable researchers to determine causes and possible non-invasive cures for neural disorders, such as epilepsy. For the recent project, Thomas DeMarse, a University of Florida professor of biomedical engineering, placed an electrode grid at the bottom of a glass dish and then covered the grid with rat neurons. The cells initially resembled individual grains of sand in liquid, but they soon extended microscopic lines toward each other, gradually forming a neural network — a brain — that DeMarse says is a "living computational device." The brain then communicates with the flight simulator through a desktop computer. "We grow approximately 25,000 cells on a 60-channel multi-electrode array, which permits us to measure the signals produced by the activity each neuron produces as it transmits information across this network of living neurons," DeMarse told Discovery News. "Using these same channels (electrodes) we can also stimulate activity at each of the 60 locations (electrodes) in the network. Together, we have a bidirectional interface to the neural network where we can input information via stimulation. The network processes the information, and we can listen to the network's response." The brain can learn, just as a human brain learns, he said. When the system is first engaged, the neurons don't know how to control the airplane; they don't have any experience. But, he said, "Over time, these stimulations modify the network's response such that the neurons slowly (over the course of 15 minutes) learn to control the aircraft. The end result is a neural network that can fly the plane to produce relatively stable straight and level flight." At present, the brain can control the pitch and roll of the F-22 in various virtual weather conditions, ranging from hurricane-force winds to clear blue skies. Not Science Fiction This brain-controlled plane may sound like science fiction, but it is grounded in work that has been taking place for more than a decade. A breakthrough occurred in 1993, when a team of scientists created a Hybrot, which is short for "hybrid robot." The robot consisted of hardware, computer software, rat neurons, and incubators for those neurons. The computer, programmed to respond to the neuron impulses, controlled a wheel underneath a machine that resembled a child's toy robot. Last year, U.S. and Australian researchers used a similar neuron-controlled robotic device to produce a "semi-living artist." In this case, the neurons were hooked up to a drawing arm outfitted with different colored markers. The robot managed to draw decipherable pictures — albeit it bad ones that resembled child scribbles — but that technology led to today's fighter plane simulator success. Steven Potter, an assistant professor of biomedical engineering at Georgia Tech who directed the living artist project, believes DeMarse's work is important, and that such studies could lead to a variety of engineering and neurobiology research goals. "A lot of people have been interested in what changes in the brains of animals and people when they are learning things," Potter said. "We're interested in getting down into the network and cellular mechanisms, which is hard to do in living animals. And the engineering goal would be to get ideas from this system about how brains compute and process information." Though the "brain" can successfully control a flight simulation program, more elaborate applications are a long way off, DeMarse said. "We're just starting out. But using this model will help us understand the crucial bit of information between inputs and the stuff that comes out," he said. "And you can imagine the more you learn about that, the more you can harness the computation of these neurons into a wide range of applications." |

Brain prosthesis passes live tissue test 18:13 25 October 04 NewScientist.com news service The world’s first brain prosthesis has passed the first stages of live testing. The microchip, designed to model a part of the brain called the hippocampus, has been used successfully to replace a neural circuit in slices of rat brain tissue kept alive in a dish. The prosthesis will soon be ready for testing in animals. The device could ultimately be used to replace damaged brain tissue which may have been destroyed in an accident, during a stroke, or by neurodegenerative conditions such as Alzheimer’s disease. It is the first attempt to replace central brain regions dealing with cognitive functions such as learning or speech. To achieve their result, Theodore Berger and his colleagues at the University of Southern California in Los Angeles, US, had to develop a system that would “read” real neural signals from healthy tissue, process them just as the lost brain tissue should, and pass on the resulting signals to the next brain area. The brain region they are trying to replace is the hippocampus, which is vital for forming memories. The hippocampus has a well-understood three-part circuit. It also has a regular repeating structure, so elements of all three parts of the hippocampal circuit can be kept in a fully functional state, even in small slices in a culture dish. Mathematical mimicry In previous work, Berger’s team had recorded exactly what biological signals were being produced in the central part of the hippocampal circuit and had made a mathematical model to mimic its activity. They then programmed the model onto a microchip, roughly 2 millimetres square. Now the team has tested whether its chip can work like the real thing. They cut out the central part of the circuit in real rat brain slices and used a grid of miniature electrodes to feed signals in and out of their microchip. “We asked if output from an intact slice was the same as from a slice with the substituted chip,” says Berger. “The answer was yes. It works really well.” The signals produced by the intact brain slice and the prosthetic hippocampus matched in shape, timing and statistics, the team revealed at the Society for Neuroscience meeting in San Diego on Sunday. “It proves you can take out a piece of a central brain region - a piece with real clinical interest - replace it with a chip, and get it to operate as it did before,” said Berger. Long-range connections The team are now working towards testing their prosthetic device on a live rat, which they expect to do within three years. They are also developing a mathematical model of primate hippocampal activity, so that they can eventually move on to testing the device in monkeys. Guenter Gross, at the University of North Texas in Denton, is impressed with the approach, but adds “the problem will be how to make the long-range connections". Even if the device can replace the local connections, he suggests, the hippocampus makes connections to many different brain regions. “There are intricate, complicated connections formed during development that cannot be replaced,” he says. Another problem is that when a region of the brain is damaged, immune cells and brain cells called glia migrate into the damaged site. They will affect any attempt to bypass or replace the damaged tissue, says Gross. However, Berger says the team are developing special electrodes coated with proteins that should mimic healthy tissue and repel the unwanted cells. There’s no reason why this approach couldn’t be used to replace any region of the brain, says Berger. “We see this as a very general approach.” |

Monkey's brain signals control 'third arm' 12:58 13 October 2003 NewScientist.com news service Duncan Graham-Rowe Monkeys can control a robot arm as naturally as their own limbs using only brain signals, a pioneering experiment has shown. The macaque monkeys could reach and grasp with the same precision as their own hand. "It's just as if they have a representation of a third arm," says project leader Miguel Nicolelis, at Duke University in Durham, North Carolina. Experts believe the experiment's success bodes well for future devices for humans that are controlled solely by thought. One such type of device is a neurally-controlled prosthetic - a brain-controlled false limb. Nicolelis says his team's work is important because it has shown that prosthetics can only deliver precision movements if multiple parts of the brain are monitored and visual feedback is provided. Gerald Loeb, a biomedical engineer at the University of Southern California in Los Angeles, says the new experiment already has some parallels in everyday life. For example, he says, when you drive a car it becomes an extension of your body. But Nicolelis says the monkeys appeared to be treating the robot arm as their limb, not an extension. "The properties of the robot were being assimilated as if they were a property of the animal's own body." Arm waving The core of the new work is the neuronal model created by the researchers. This translates the brain signals from the monkey into movements of the robot arm. It was developed by monitoring normal brain and muscle activity as the monkey moved its own arms. The task involved using a joystick to move a cursor on a computer screen. While the monkey was doing this, readings were taken from a few hundred neurons in the frontal and parietal regions of the brain. The activation of the biceps and wrist muscles was monitored, as was the velocity of the arms and the force of the grip. Once the neuronal model had developed an accurate level of prediction the researchers switched the control of the cursor from the joystick to the robotic arm, which in turn was controlled by the monkey's brain signals. At first the monkeys continued moving their own arms whilst carrying out the task, but in time they learned this was no longer necessary and stopped doing so (see Flash animation. For Nicolelis, the end goal is to help people with paralysis by bypassing brain lesions or damaged parts of the spine. Initially patients would control robotic aids, such as a mechanical arm attached to a wheelchair. But eventually the signals could be used to stimulate the nerves controlling a patient's own muscles. Nicolelis and his team have already begun to testing this approach on people, but he says it is too early to discuss this research.

Old news, British have this too or so someone who worked in that field told me. I believed him, then and now even more so. He mentioned they where thinking about releasing it to the public in two years...
It would suck to have your brain hacked into O_o. |

So far it only works one way. Although its probably only a matter of time before two way communication is possible. The Internet is so filthy already that direct brain access to it may already be unsafe, even before we have tried. Try the Ghost in the Shell movies and books to see some of the ways this has already been contemplated. |

Chip ramps up neuron-to-computer communication
Web Links NACHIP Project Structural and biological physics, University of Padua A specialised microchip that could communicate with thousands of individual brain cells has been developed by European scientists. The device will help researchers examine the workings of interconnected brain cells, and might one day enable them to develop computers that use live neurons for memory. The computer chip is capable of receiving signals from more than 16,000 mammalian brain cells, and sending messages back to several hundred cells. Previous neuron-computer interfaces have either connected to far fewer individual neurons, or to groups of neurons clumped together. A team from Italy and Germany worked with the mobile chip maker Infineon to squeeze 16,384 transistors and hundreds of capacitors onto an experimental microchip just 1mm squared. When surrounded by neurons the transistors receive signals from the cells, while the capacitors send signals to them. Each transistor on the chip picks up the miniscule change in electric charge prompted when a neuron fires. The change occurs due to the transfer of charged sodium ions, which move in and out of the cells through special pores. Conversely, applying a charge to each capacitor alters the movement of sodium ions, causing a neuron to react. The researchers began experimenting with snail brain cells before moving on to rat neurons. "It is harder using mammal neurons, because they are smaller and more complex," Stefano Vassanellia molecular biologist with the University of Padua in Italy told New Scientist. The researchers took a twin-track approach to developing the system, he says: "We improved the chip, and also the biology." The team had to tinker with the neurons themselves to increase the strength of the connection between cells and the chip. Pore connection Firstly, the researchers genetically modified the neurons to add more pores. Secondly, they added proteins to the chip that glue neurons together in the brain, and which also attract the sodium pores. Applying this neural glue meant that the extra sodium channels collected around the transistor and capacitor connections. This improved its chance of translating the movement of ions into electrical signals on the chip. Having boosted the electrical connection between the cells and chip, the researchers hope to be able to extend the chips influence further. "It should be possible to make the signals from the chip cause a neuron to alter its membrane and take up a new gene, or something that switches one off," says Vassanelli. "Now the chip has been developed, we plan to use it to try and switch genes on and off." A compound that would turn off a gene, or the DNA for a new one, could be added to the dish containing the wired-up neurons. Using the chip, it would be possible to control exactly which neurons took them up, and which did not. Having this level of control over many thousands of connected neurons would provide new insights and make new applications possible, Vassanelli says. "It would definitely improve our ability to experiment and understand the workings of neurons, and this development could also provide a whole new way to store computer memory, using live neurons," he says.
