University of Chicago researchers aim to design prostheses that will
not only be able to move, but would also provide amputees and
quadriplegics a sense of touch.
In an underground laboratory at the University of Chicago,
neuroscientist Sliman Bensmaia peered at a computer attached by wires
to a rhesus monkey's brain.
Brain-controlled limb to take prosthetics a step forward, researchers
A lab technician grazed the animal's finger using a metal probe, and
the computer screen erupted in red. "That's pretty cool," Bensmaia
said, grinning. "You can see the brain becoming active just by
tapping the hand."
Next, instead of physically tapping the animal's hand, the technician
planned to run a small current of electricity through electrodes in
the animal's brain to simulate the probe. If the animal looked in a
certain direction, the scientists would know the "virtual touch"
This research is part of a groundbreaking quest to accomplish what
was once the stuff of science fiction - build a machine that helps
