Manipulate artificial hand by thought

Most of the prosthetics today for amputees use high technology. But for Jesse Sullivan, his prosthetic arm is particularly intelligent as it is controlled by the mind of the owner.

The scientists connected the nerve root of Sullivan's chest muscles to the prosthetic arm, which made the arm more active. When he thinks, the nerve signals are transferred to the chest muscles, then translated by a computer software to affect the arm. Sullivan was first operated eight years ago and is still being monitored by scientists.

According to the Daily Mail, scientists at Northwestern University (USA) are continuing to search for different models of brain activity to control the operation of the prosthesis better. Nate Bunderson, who presented the study at the Neuroscience Symposium held in San Diego, said the team used brain signals to control the device. They have adapted the brain's signal transduction system to help patients better control the limbs, working on a wider scale. This technology is a great hope for people with disabilities.
