Exploring the Interconnection Between Memory and Movement

Today we are re-releasing an episode we did last year with Stanford neurobiologist Lisa Giocomo exploring the intersection of memory, navigation and the boundaries we create between ourselves and the world around us.

This episode was inspired by the idea of memory palaces. The idea is simple: Take a place you're very familiar with, say the house you grew up in, and place information you want to remember in different locations within that space. When it's time to remember those things, you can mentally walk through that space and retrieve those items.

This ancient technique reveals something very fundamental about how our brains work. It turns out that the same parts of the brain are responsible both for memory and for navigating through the world.

Scientists are learning more and more about these systems and the connections between them, and it's revealing surprising insights about how we build the narrative of our lives, how we turn our environments into an internal model of who we are, and where we fit into the world.

Join us to learn more about the neuroscience of space and memory.

Before we get into this week’s episode, we have a favor to ask. We're working to make this show even better, and we want to hear from you. We're in the process of gathering listener input and feedback. If you'd be willing to help out, send us a short note and we'll be in touch. As always, we are at neuronspodcast@stanford.edu

• About Lisa Giocomo’s research
• About the story of Henry Molaison (patient H. M.), who lost the ability to form new memories after epilepsy treatment removed his hippocampus.
• About the 2014 Nobel Prize in medicine, awarded to John O’Keefe and to May-Britt and Edvard Moser (Giocomo’s mentors) for their discovery of the GPS system of the brain.
• About Memory Palaces, a technique used since ancient times to enhance memory using mental maps.
