Brain-machine interface allows control of limbs through thoughts

By placing a small sensor in the brain’s motor cortex, interfaces can pick up on electrical activity, and translate it into commands that control a robotic arm. Now scientists have gone a step further. Instead of a wired brain-arm link, they have now developed a wireless connection powerful enough to work at a distance of three feet.

“Clinical applications may include thought-controlled prostheses for severely neurologically impaired patients, wireless access to motorized wheelchairs or other assistive technologies, and diagnostic monitoring such as in epilepsy, where patients currently are tethered to the bedside during assessment,” says David Borton, at Brown University.
