A monkey fitted with a hi-tech brain chip has learned to move a complex robotic arm using mind control.
The chip implant allows the monkey to manipulate the arm by thought. The animal can operate the robot with such dexterity that it can reach out to grab, and turn a handle.
The mechanical arm has an arm, elbow, wrist and simple hand, which the monkey controls with the power of thought.
The research is progressing so rapidly that scientists hope to start trials on paralysed patients within a year. Neurobiologist Dr Andy Schwartz said: "What we're trying to do is go to a very dextrous hand - where the functionality is very similar to the human hand. If we could help stroke patients there would be a huge market for this kind of device." SKY NEWS
