[TED Talk] Sandrine Thuret: You can grow new brain cells. Here’s how

Until recently, it was believed that adult brains simply didn’t grow new brain cells — what we developed as children was all we got. But now we know our brains can grow new nerve cells, in a process called neurogenesis, throughout our entire lives. Neuroscientist Sandrine Thuret studies how we do that, and offers research and practical advice on how we can help our brains grow — and why we should.
