Didn;t someone accomplish this in late 2002?

  From Duke University News: Research may lead to advances allowing paralyzed people to control prosthetics by thought. In their first human studies of the feasibility of using brain signals to operate external devices, researchers at Duke University Medical Center report that arrays of electrodes can provide useable signals for controlling such devices. The research team is now working to develop prototype devices that may enable paralyzed people to operate "neuroprosthetic" and other external devices using only their brain signals. While the new studies provide an initial proof of principle that human application of brain-machine interfaces is possible, the researchers emphasize that many years of development and clinical testing will be required before such neuroprosthetic devices are available. Application of such technology would be a robot arm for a quadriplegic, a neurally controlled electric wheelchair, and another a neurally operated keyboard, whose output could include either text or speech. Such devices could help both paralyzed people and those who have lost speech capabilities. A key question in future clinical studies will be whether humans can incorporate such devices into their "schema," or neural representation of the external world.
