[QUOTE=GregtheSleeper]Isn't that the thing where you have your head 'bluetoothed'? I was reading an article about a guy who severed his spinal cord and some neurologists hooked up some wires to his motor region. He could then use a robotic hand to pick up stuff. The technology is still in its infancy, but it looks promising.[/QUOTE]
No, that's a different technique, you can read more about neuromotor prosthesis here in the original article:

The things I wished for, selective radioligands, have to do with the possibility to study the transmitter substances in the brain. The brain cells communicate with each other via various chemical substances, neurotransmitters, and those are fundamental for brain function. You can read a little about it here:

Apart from needing molecules that allow studying the activity of these neurochemical systems in the brains, we also need a better spatial resolution in order to study the brain's small nuclei, that are like relay stations for various functions. Since the method is based on detection of the photons emitted when matter and anti-matter (positron and electron) collide, Heisenberg's uncertainly principle sets a limit for preciseness, which I would like to get rid of
