If you’re a brain, it can be tough to stay organized. The world comes at you fast, from all angles, in different sensory formats—sights, sounds, smells. You need to take it all in, but you also need to parse it, process it, categorize it, remember and learn from it. And of course you also need react to it, preferably appropriately. So what do you do—as a brain—to handle this organizational overload? Well, for one thing, you make maps. Lots of maps.
My guest today is Dr. Rebecca Schwarzlose, a cognitive neuroscientist and author of the new book Brainscapes: The warped, wondrous maps written in your brain—and how they guide you. Rebecca is former editor of Trends in Cognitive Sciences and is currently a postdoctoral scholar at Washington University in St Louis. Her book was supported by the Alfred P. Sloan Foundation’s program in the Public Understanding of Science and Technology.
In this conversation, Rebecca and I talk about what brain maps are and why brains evolved to make them. (And just to be clear, it’s not just human brains—it’s the brains of many creatures.) We talk about how delightfully warped these maps are —and, of course, why. We discuss how we rely on them for vision, touch, smell, and movement, not to mention for thinking about faces, places, numbers, and more. We also discuss the fascinating duality at the heart of these brain maps, which is their balance of universal and unique features.
I just love this angle on neuroscience, this way of thinking about the brain as a restless, prodigious cartographer. I thoroughly enjoyed Rebecca’s book. And definitely there’s a lot in it we couldn’t touch on in this episode—details about how the mustache bat makes echolocation maps, for example, and about how new techniques are leveraging brain maps to do something like mindreading. So I hope you enjoy the episode, but I also hope you go and check out Rebecca’s book for yourselves.
Alright folks, on to my conversation with Dr. Rebecca Schwarzlose. Enjoy!
