Unused bandwidth in neurons can be tapped to control extra limbs:

What could you do with an extra limb? Consider a surgeon performing a delicate operation, one that needs her expertise and steady hands—all three of them. As her two biological hands manipulate surgical instruments, a third robotic limb that's attached to her torso plays a supporting role. Or picture a construction worker who is thankful for his extra robotic hand as it braces the heavy beam he's fastening into place with his other two hands. Imagine wearing an exoskeleton that would let you handle multiple objects simultaneously, like Spiderman's Dr. Octopus. Or contemplate the out-there music a composer could write for a pianist who has 12 fingers to spread across the keyboard.

Such scenarios may seem like science fiction, but recent progress in robotics and neuroscience makes extra robotic limbs conceivable with today's technology. Our research groups at Imperial College London and the University of Freiburg, in Germany, together with partners in the European project NIMA, are now working to figure out whether such augmentation can be realized in practice to extend human abilities. The main questions we're tackling involve both neuroscience and neurotechnology: Is the human brain capable of controlling additional body parts as effectively as it controls biological parts? And if so, what neural signals can be used for this control?

[...] Two practical questions stand out: Can we achieve neural control of extra robotic limbs concurrently with natural movement, and can the system work without the user's exclusive concentration? If the answer to either of these questions is no, we won't have a practical technology, but we'll still have an interesting new tool for research into the neuroscience of motor control. If the answer to both questions is yes, we may be ready to enter a new era of human augmentation. For now, our (biological) fingers are crossed.

    New idiom:

    "On the one hand, we could do the thing, and make lots of money. On the other hand it could fail and we would be sunk. On the gripping hand, we will all get fired if we don't do anything, so we might as well give it a whirl."
