Brain Power: Mind Control of External Devices

But if the person is a quadriplegic controlling the cursor with nothing but brainwaves, now that would be interesting. And it's been done.
Brain-computer interface systems, although still in developmental and experimental stages, are becoming increasingly more powerful and applicable. Advancements in neural signaling research make it one of the hottest fields in biomedical engineering.
Better sensing systems
Earlier this year, researchers indeed trained four people suffering epilepsy to move a computer cursor with the power of thought. The patients, who were waiting to have brain surgery, were already fitted with small sheets of signal-detecting electrodes on the surfaces of their brains.
The patients were asked to perform certain tasks – such as opening and closing their hands and sticking out their tongue – while scientists determined what brain signals were associated with these movements.
Next, the signals from these movements were matched up with movements of the cursor on the screen. For example, the thought of opening of the right hand might move the cursor to the right. The subjects were then asked to move the cursor from one spot to another on the screen by thinking about making the movements.
The patients had some difficulty at first, but each was able to control the cursor with their thoughts and with over 70 percent accuracy after a few minutes. One patient was operating at 100 percent accuracy by the end of the trial.
"All our subjects were able to control the computer cursor using imagined representations of motor movements," said Daniel Moran of Washington University.
This study was the first to prove that sensors placed on the surface of the brain are preferable to the standard forms of sensors – either embedded deep in the brain tissue or worn as a cap. They are less intrusive than an embedded variety and potentially more stable and powerful than the cap, which receives weak brain signals that have passed through the skull.

He has very limited movement in his entire body and has been in a wheelchair since he was 10.
Stanford Hospital put him in a full body cast for a year thoroughly imobolized when he was 9, and after they took it off he never walked again.
Every thing that most people take for granted like moving a computer mouse, writing a check or making lunch is a monumental task for him
He's a brilliant guy though, and this kind of thing would make an enormous difference in his life.

Its amazing what modern science can do...Recently I saw a show the PSI factor ( the chronicles of the paranormal) in AXN channel...It dealt with a story which told how an actual computer virus killed the person working with the computer...I cudnt see the show completely,but is it possible for such a thing to happen,they had classified this as paranormal activity...Do let me knw if u hve heard smething that refers to a similar incident...and also abt what u said abt people being able to control ones senses through these stimulators attached to their brain..SO when it comes to telekinesis what is the actual phenomenon that happens...I would very much appreciate it if u could help me on this...May God Bless, take care and thank u..

Our brains send electrical signals down these corridors to make things work. Why can't we just tap into them as they enter the neck? I know a lot of peole have nerve damage but it is usally lower in the body. My damage is where my neck and spine come together.
