BrainGate - Earth Scientists Begin To Crack Krell Secrets
BrainGate, a tiny sensor array implanted in the brain, has allowed a quadriplegic man to check e-mail and play computer games - even manipulate the controls on a television. It is the most sophisticated implant of its kind.
(From Nature)
The Cyberkinetics BrainGate contains 100 electrodes, each one tapping into a separate neuron. Placed in the motor cortext, it allows the user to control objects while doing other things at the same time.
(From Cyberkinetics Video)
"The principle of operation of the BrainGate Neural Interface System is that with intact brain function, neural signals are generated even though they are not sent to the arms, hands and legs. These signals are interpreted by the System and a cursor is shown to the user on a computer screen that provides an alternate "BrainGate pathway". The user can use that cursor to control the computer, just as a mouse is used." (From BrainGate Technology)Cyberkinetics has plans to implant the devices in 4 more subjects; the company cautions that BrainGate is an investigational device for clinical testing only. It is not an approved device.
(From Forbidden Planet 1956)
As far as I know, the first reference to a machine that is attached to the brain (or placed in proximity to the brain) that will allow a user to control mechanical devices with thought is in Forbidden Planet. In the picture shown above, Dr. Morbius is able to use the Krell machinery to create a 3D picture of his daughter by thinking about it.
