Monkey Uses Brain to Move Robotic Arm

I haven't read much about this, but it gives hope towards the idea of making life easier for paraplegics or other amputees. I'm very curious to know where the electrodes are placed in his (or her) brain and how they trained him to use the arm. Like any physical skill, I assume it just requires practice, and then becomes second nature.

Yet another example the Singularity is Near...

I'm no PETA member, but I always feel bad for the monkeys in experiments like these, poor little guy just wants his marshmellow.
