href="http://www.dukenews.duke.edu/news/studies_0304.html">Duke University
News</A>: 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.</DIV>
