Here’s a great resolution for 2025: learn everything you didn’t know you didn’t know about the brain. Sign up for my new course on Peterson Academy.

Your vast forest of 86 billion neurons is adjusting itself every moment of your life, cradle to grave. In this course, you’ll learn the overarching principles of brain plasticity: how the brain comes to capture the details of its outside world, how circuitry is modified by activities and goals, why it’s harder to teach an old dog new tricks, how we remember, and disorders of plasticity, how it adjusts itself to its body and senses — and how new body plans and senses can be added. Discover why learning becomes more challenging with age, uncover the mechanisms behind memory, the role of relevance in expertise, and strategies for maintaining brain health. This course takes you on a whistlestop tour of the principles that make the brain the most remarkable thing we have ever discovered.
