Prosthetic arm directly controlled by brain signals

Today I attended a talk by Prof Andrew Schwartz from University of Pittsburgh. His group successfully created am artificial arm for a monkey, which was published in Nature in 2007. The research reminded me of an animation, Fullmetal Alchemist, in which a boy Edward lost his arm and had to make use of his prosthetic arm throughout the story.

Science realizes fiction.

 

However, scientists are smarter than the writer. Instead of connecting the prosthetic arm to the body neuron by neuron, they just retrieve the signals in brain (motor cortex), decode them and command the prosthetic arm to move.

    I’ve heard about that. Do you think it is good? Is the plot the same as the old one or different?
