Monkeys control computer using brain; are teknoguilders

Monkeys have been trained to control a virtual arm on a computer screen using only their brain waves.

In the experiments, a pair of rhesus monkeys was trained to control a virtual arm on a screen solely by the electrical activity generated in their brains.
Thanks to feedback from the experimental setup, the monkeys were also able to feel texture differences of objects on the screen.

The researchers involved say that just like a normal functioning limb, the monkeys were able to do both actions at the same time, sending out signals to control the arm while simultaneously getting electrical feedback to understand the texture of the objects that were touched.

Writing in the journal Nature, the researchers say their work could speed up the development of wearable exoskeletons. This technology could help quadriplegic patients not only regain movement but a sense of touch as well.
