Heinäkuun 10tenä lähetetty Next@CNN tiedeohjelma esitteli tutkimusta, jossa apinoilla kokeillaan halvaantuneille tarkoitettuja, ajatuksella ohjattavia hitech laitteita.
Kyse on siis aivotutkimuksen sovelluksista, jossa *ajatus korreloituu dataksi* ja suorittaa käskyn jollekin laitteelle.
Käsittääkseni tämä lääketieteellinen sovellus kulkee jäljessä.

En valitettavasti saanut koko sivua latautumaan auki, mutta tässä osa tekstistä:
"Well, researchers may be close to helping paralyzed individuals to communicate and control their own activities. Scientists at CalTech are learning more about parts of the brain that may allow people to simply think about certain tasks and then let their brainwaves make them happen. Femi Oke has our story.

CHRISTOPHER REEVES, ACTOR: Thank you for inviting me here today. Thank you very much.
(APPLAUSE)
FEMI OKE, CNN CORRESPONDENT: Christopher Reeves' Paralysis Foundation helped fund this research at the California Institute of Technology. The goal, to harness brain signals so paralyzed people can operate computers, steer wheelchairs, even drive cars.
RICHARD ANDERSEN, CALIFORNIA INSTITUTE OF TECHNOLOGY: The patient, who is paralyzed, of course, can still about making movements. If they can't speak, they can often think about the words they would like to say. So what this research shows is that some of those signals can be directly read out from brain signals. And then these brain signals could be used for them to more effectively communicate with the outside world.
OKE: The CalTech research, reported in this week's "Science" magazine, details how three healthy Reeses moneys, learned to position a curser on the computer screen just by thinking about reaching to that position. Scientists monitored and recorded signals from brain neurons by a tiny electrode surgically implanted in the animal's head to pinpoint where the thoughts originated.
ANDERSEN: Monkeys, in a few trials, all of them learned to do this task, to just simply think about making a reach, and they successfully performed it.
OKE: These brainwaves could be used to trigger controls on all sorts of external devices, a keyboard, a robotic arm, a vehicle. The study was conducted over a period of years, and the animals have now been retired to a sanctuary.
Previous research has focused on the area the brain involved in the actual movement.
ANDERSEN: The area that we're looking at is one step prior to the motor areas that provides the, in a sense, the idea to make a moment.
DR. PHILIP KENNEDY, NEUROLOGIST: This is the kind of signals we get and that...
OKE: Dr. Phillip Kennedy has helped develop brain and muscle communicators for human patients locked in by strokes, paralysis, or ALS, Lou Gehrig's disease.
KENNEDY: We do it several ways, either by connecting directly from the brain or from muscle activity or eye movements, or just micro searches. But we're -- we have been able to unlock people who thought they were locked in and let them communicate via computers.
OKE: Kennedy says, patients like J.R., now deceased, have shown him remarkable courage.
KENNEDY: All of our patients have been really, really ill and some are really brave people and I just have to admire them. "
