The BBC version has some interesting quotes [with my comments]
http://news.bbc.co.uk/2/hi/science/nature/7423184.stm
Commenting on the paper, Professor Paul M Matthew from the Hammersmith
Hospital, said: "The challenge of interfacing the billions of nerve
cells in the brain that control the full range of limb movements
directly with a mechanical prosthesis has seemed impossibly difficult.
[Yes, it would so appear if you are trying to compute outputs based on reverse kinematics and dynamics.]
"However, this important paper confirms that the brain controls
movement just by planning where to go, rather than by directing
individual muscles how to make the limb get there.
[I wonder if “just by planning where to go” might refer to controlling perceptions.]
"The study shows that fewer than 100 tiny electrical signals generated
in the specialised area known as the ‘motor cortex’ can command even
complex arm and hand movements.
[Apparently not.]
