Soon we'll see "living" UAVs.

Well if the UAV does indeed have a 'rat-brain' Neo-Cons are in some danger.

New fly-by-rat F-22s under development

Skynet has become self aware. In one hour it will conduct a massive nuclear attack on its enemy.

What could possibly go wrong?...

Here's the article;

Brain in a Dish Flies Plane
By Jennifer Viegas, Discovery News

type size: [A] [A] [A]

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.

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."

Oops, just saw Distiller's post. Merging with that one.

Wasn't there a Russian computer reasercher who also tried to use living brain cells (from a rat also if I remember correctly) in a computer. I remember reading about that somewhere for sure.

Next, they'll move onto human brain cellls. Mwaa haa ha.

hmm. i don't think that's anything that can't be done with a modern computer and some good algorithms. UAVs and autopilots nowadays already do better than that rat brain in the F-22 simulator.

i'm not doubting the potential of this though - soon organic artificial brains would probably indeed be more powerful than chips-and-wire computers. bioneural gelpacks anyone?

throughout history , we the members of the Great Pack have been insulted, hunted, had dogs and cats chase them and kicked in the gut.

It is time my friends to arise from our holes to reclaim our legacy and rule what was once ours! *2 billion rats point their AK47s in the air and fire off bursts in agreement*

TV footage shows downtown office workers running in sheer terror as a boiling army bandicoots emerges from the sewers and shoots at anything..
