You Can Grow Your Brain. Here’s How.

You Can Grow Your Brain. Here’s How.

Author: Next Big Idea Club May 11, 2026 Duration: 1:20:13
In the last 20 years, there has been a dramatic change in our understanding of neuroplasticity — the brain’s capacity to grow new neurons. In the last five years, we’ve learned that your hippocampus, the part of your brain responsible for learning and memory, can get bigger at any age. Majid Fotuhi, who teaches at Johns Hopkins, has been at the forefront of a new body of research demonstrating that lifestyle changes — tweaks to the way you exercise and eat, adjustments to your sleep and mindset — can improve your brain health no matter how old you are. They can even reverse early-stage Alzheimer’s. His new book is The Invincible Brain, and the message is clear: with the right lifestyle and mindset changes, you can grow a bigger brain. 🔗 LINKS AND MENTIONS: Check out our playlist of health-related episode on Spotify The Next Big Idea Club — Save 20% on any membership when you use code PODCAST at nextbigideaclub.com Granola — If meetings are eating up your day, Granola is a no-brainer.

Each week on The Next Big Idea, hosts Rufus Griscom and Caleb Bissinger sit down with authors and researchers whose ideas are shaping our culture, education, and understanding of society. The conversations are guided by a unique group of curators-Malcolm Gladwell, Adam Grant, Susan Cain, and Daniel Pink-who help frame these discussions around the most compelling new concepts in science and social thought. This isn't just an interview podcast; it's a deep exploration of the books and theories that have the potential to shift perspectives and spark meaningful change. You'll hear the stories behind the ideas, the personal journeys of the thinkers, and practical insights that extend beyond the page. The dialogue is structured yet spontaneous, offering listeners a genuine sense of being part of a substantive conversation. Episodes are released every Thursday, providing a consistent dose of intellectual curiosity. The podcast is produced by the Next Big Idea Club, an organization dedicated to surfacing and discussing transformative knowledge. Whether you're looking to understand the nuances of human behavior, the latest scientific discoveries, or the forces driving social change, this series serves as an accessible gateway to complex topics. The aim is to make big ideas feel relevant and engaging, without oversimplifying their importance. Tune in for a thoughtful break from the noise, where the focus is entirely on understanding what comes next.
