ROBOT LIMBS WITH THE MIND [ back
to What's New ]
Following stroke, spinal cord injury or TBI to a portion of
the motor cortex, a person becomes "paralyzed,"
and cannot move the affected arm or leg. Scientists have been
working on ways to move robotic limbs to enable people to
compensate for such paralysis. The cyber approach has been
to program a network of computers with a program resembling
the neural signal for limb movement, which can trigger motion
in a robotic arm. A more biological approach was reported
in November 2000 by Dr. Miguel Nicolelis, a neuroscientist
at Duke University, who used motor signals from the brains
of living owl monkeys to move a robotic arm. This an important
first step in the development of a neural prosthesis, which
may one day be used by human beings.
