Mind control on horizon for wheelchairs and limbs
Print Edition
THOUGHT-CONTROLLED prosthetic limbs, wheelchairs and computers may be available within a decade, say Australian scientists who are planning to conduct human trials next year on a high-tech implant that can pick up and transmit signals from the brain.
Animals have already been tested with the device, called a stentrode, which is the size of a matchstick and planted inside a blood vessel near the brain.
It uses a web of small electrodes to pick up neuron signals from the brain and converts them into electrical commands that may one day, the scientists hope, allow paralyzed patients to control a bionic limb or wheelchair.
“The big breakthrough is that we now have a minimally invasive brain-computer interface device which is potentially practical for long-term use,” said Terry O’Brien at the University of Melbourne.
