Brainscapes: the maps in our brain

If the brain's 86 billion neurons were all randomly connected, the brain would have to be more than 20 kilometres wide to fit all those connections. Luckily, they're instead organised through brainscapes, or brain maps. Rebecca Schwarzlose is a cognitive neuroscientist at Washington University in St. Louis, Missouri and has just published Brainscapes: An Atlas of Your Life on Earth. She explains how the brain is full of maps; of the body, our senses, how we move, and crucial sources of information. And Rebecca isn't being metaphorical or using artistic license - these are actual maps in your brain. And it's not just a few of them; there's a whole atlas of them. Lynn asks Rebecca Schwarzlose what a brain map actually is.
