Episode notes

In the 19 sixties, a naro scientist named wilder penfield was the first to discover that there's a map of the body in the brain. And so what this tells us is that its activity dependent and depending on the information streaming up into the brain, the brain changes its map of what's going on. When people lose limbs or when they gain extra sensory things, they can rewire the brain,. i suppose it's a better way o sayit, to adapt to that new kind of body that they have. The not having half a brain is obviously a dramatic example of this.

Imagine you were locked in a sealed room, with no way to access the outside world but a few screens showing a view of what’s outside. Seems scary and limited, but that’s essentially the situation that our brains find themselves in — locked in our skulls, with only the limited information from a few unreliable sensory modalities to tell them what’s going on inside. Neuroscientist David Eagleman has long been interested in how the brain processes that sensory input, and also how we might train it to learn completely new ways of accessing the outside world, with important ramifications for virtual reality and novel brain/computer interface techniques.
