This is closer to the neuro-scientific side of Artificial Intelligence, but still relevant and fascinating enough to mention here. An article on Science Daily mentions that researchers have managed to simulate on monkeys what is effectively 3D control of an object; Thought-Controlled Prosthetics? With a bit of help from AI to facilitate the limb movement, this could be directly applied to controlling prosthetics without a nervous system. I guess the system developed would class as an artificial nervous system. There's still a long way to go, but here's another step (pardon the pun ;)

This development is amazing, I can't believe they can already read brains well enough to make something like this. An extremely novel idea. I'm also really excited by the implications. Doesn't this mean that we can soon do similar things to ourselves? Imagine how fast we could type if our thoughts corresponded directly to the word processor! Obvious problems are inherent in this logic, but it is still fun to think about... A cool article, thanks for the link!
