S3 Ep3: The Society of Cells: Brainbow Mapping with Jeff Lichtman

Neuroscientist and Harvard Professor Jeff Lichtman walks Jerry through his astonishing work mapping the human brain. In 2024, with the help of Google Research, Jeff’s team developed the most detailed map of a human brain sample ever created, producing 1,400 TB of data from a sample the size of a pinhead.

Jeff also talks about how he and Harvard biologist Dr Joshua Sanes pioneered the Brainbow process, a breakthrough that allows scientists to easily identify individual neurons in the brain by colour.

He goes on to explain how our experiences allow us to build neural maps, or wiring diagrams, onto our brains. These maps encode our memories and learned experiences, so that we can act without thinking, like riding a bicycle.

From historians, scientists and writers to creatives and cultural custodians, people have used maps as a source of knowledge, guidance, and inspiration for centuries.
Join award-winning expert Professor Jerry Brotton as each episode he invites a guest to share a map close to their heart - and unfurl the ideas, inspirations, and stories behind it.
So if you’re fascinated by history, art, adventure and culture, why not become part of a global community of fellow explorers as we ask - What’s your map?
