Excerpts:
Somewhere in Florida, 25,000 disembodied rat neurons are thinking about flying an F-22.
These neurons are growing on top of a multi-electrode array and form
a living "brain" that’s hooked up to a flight simulator on a desktop
computer. When information on the simulated aircraft’s horizontal and
vertical movements are fed into the brain by stimulating the
electrodes, the neurons fire away in patterns that are then used to
control its "body" — the simulated aircraft.
Currently the brain has learned enough to be able to control the
pitch and roll of the simulated F-22 fighter jet in weather conditions
ranging from blue skies to hurricane-force winds. Initially the
aircraft drifted, because the brain hadn’t figured out how to control
its "body," but over time the neurons learned to stabilize the aircraft
to a straight, level flight.
"Right now the process it’s learning is very simplistic," said
DeMarse. "It’s basically making a decision about whether to move the
stick to the left or to the right or forwards and backwards and it
learns how much to push the stick depending upon how badly the aircraft
is flying."
The bigger goal is to figure out how neurons talk to each other. MRI
scans, for example, show millions of neurons firing together. At that
resolution, it is impossible to see what’s happening between individual
neurons. While scientists can study neural activities from groups of
cells in a dish, they can’t watch them learn and grow as they would
within a living body unless the neurons have some kind of body to
interact with.
By taking these cells and giving them back a "body," the researchers
hope to uncover how the neurons communicate with each other and
eventually translate that knowledge to develop novel computing
architecture.

And this just in from UNIVERSE TODAY:
In related news, EarthForce defense contractors announced
project aimed at creating a powerful "shadow" warship using a human
being as its central processing unit."We’re very excited about the new shadow ship," said Gen. Wink
Tinkley of EarthForce. "Using a human being as the CPU means a lot more
computing than a simulated rat brain has. The only problem we’ve found
is that telepaths can interfere with the human’s neural connection with
the ship."EarthForce contractors also announced the creation of an even more
ambitious program which will allow a detachable human as a ship’s CPU.
When perfect, this pilot program will allow humans who pilot such
ships–known as "pilots"–to live normal lives by being extracted from
their ships at the end of missions.
I was wondering when some one would whisper, “Shadows.”
“Wink Tinkley” ??
maybe it’s just me, but this is just plain weird and scary.
How long oh Lord?
Very weird, though the lack of peer publishing on this does make me a mite skeptical about what they’ve actually accomplished. Wired.com is a lot of fun, but they strain so earnestly to be “bleeding edge” that they sometimes jump the gun and report things too soon.
Could someone stop the world please. I’d like to get off.
Back in my Air Force days, the common saying was:
“…with enough bananas, we can train anyone to be a pilot…”
Obviously we had the wrong food group-cheese would be more correct.
Also, this story should be more than sufficient to make most pilots a bit more humble.
Um . . . Eew!
I’m with TimM & LawfulGood. Is my condo on the moon ready yet?
This is really creepy. If this “thing” can really fly how do we know it’s not in pain? How do we know anything about what is really going on?
While my geek side is facinated with this my moral side wonders if we should be doing this at all. Hmm…now that I type that I am wondering if that that means geek and moral don’t go together. Perhaps my moral side keeps my geek part in check. I hope I’m not ever split into two people by a transporter malfunction.
“Rat brains are now being used to pilot fighter planes for the US Air Force.
In a related story, it seems a military jet mysteriously crashed into a cheese processing plant earlier today, wounding three people…”
