GW:
One story of yours that really amazed me was how in virtual reality, you can attach a tail to someone and they immediately know how to control it. I wonder if that relates to the inbetweenness you’re describing.
JL:
The fact that you can take on different body plans and still control your body is one of the most startling and surprising results of virtual-reality research. It’s probably the most significant scientific discovery to come out of virtual-reality research, actually.
It was known before that you could alter the body to a degree, because of phantom limb research and other related investigations. But the notion that you could radically reorganize the body and the brain could still control it was not something that could have been tested before. And it is remarkable. One thing that's probably going on is that the brain remembers body forms that our ancestors inhabited, because as far as the brain is concerned evolution is a slow, gradual process. So the brain remembers what it was like to have a tail.
There have been a few different experiments with putting a tail on a person in virtual reality. But the best, most rigorous work came out of Mel Slater's lab at University College London. That particular tail was a really good tail. It was a long tail. And the task was to get it to whip around in front of you to hit a target. So it was a pretty non-trivial bit of athleticism with your tail. And people can just do it. I mean, it's natural. Everybody's brain knows how to run a tail.
The more striking experiments involved changing people into completely different creatures with different numbers of limbs, or with limbs attached strangely. And there you start to see a kind of jigsaw puzzle, where there are some body designs that brains can control and some that it seems that they can't. What we're unveiling is the brain's own cartography. We’re discovering what world the brain thinks it's inhabiting, or what body it thinks it's part of. And the body that your brain thinks it's part of is not just your body at the moment—it's a multi-million-year stream of changing bodies.
