Monkey controls robot arm with mind

I saw a really positive piece on the BBC news the other night about monkeys who have been 'adapted' to control robot arms with their minds.

The piece was overwhelmingly in favour, saying this was a step forward and could help people who have been paralysed and so on.

Fair enough, but I did notice something rather odd.

If you look at the picture here, you'll notice something blocking out the top of the little chap's head.

It's not attached to to monkey, the silver metal thing is in the foreground. Now, this device works by connecting electro circuits to their brains.

So presumably behind this blocking bit of metal, the poor thing's head has been sawn off with large crocodile clips clamped to its brain.

I suppose it wouldn't have garnered such positive coverage if this had been visible...
