Dr Karl

We haven't bothered to get photos of it, but I'm pretty sure that it's very bumpy.

I don't think it's round.

So there you go.

Dr. Mike, I hope that answers your question.

And best of luck with getting your own planet named after you.

I am here to obey.

Wow, way back in Nature magazine when I was a scientific officer at Prince Henry Hospital in 1978, the front cover was an X-ray of a human skull with a socket into it.

a big fat socket like three or four centimetres in diameter.

And the guy had had his face blown off in a shotgun accident and he'd lost his vision.

And what they did was put a socket into the back of his brain and then wire it up to the visual cortices at the back of his brain and hook it up to video cameras and he could kind of pick up vision on an 8x8 grid or...

Or 16 by 16, he could at least see things coming towards him and going away, and there were problems with it.

Since then, we've advanced mightily.

So already there are a quarter of a million people with computers deliberately buried in their brains to help them deal with Parkinson's disease.

Huntington's career and Alzheimer's disease.

Look up the videos of the people with Parkinson's disease who hand are shaking and they manage to activate the computer in their brain and their hands stop shaking.

It's quite astonishing.

There was a woman who is locked in, which means her brain works, but she can't move any of her body.

And they put chips in her brain and she can think a thought

and then a computer can say what she's thinking.

That's really clumsy, but we're getting it to work better.
