Book excerpt: A candid and practical guide to the new frontier of brain customization Dozens of books promise to improve your brain function with a gimmick. Lifestyle changes, microdosing, electromagnetic stimulation: just one weird trick can lightly alter or dramatically deconstruct your brain. In truth, there is no one-size-fits-all shortcut to the ideal mind. Instead, the way to understand cognitive enhancement is to think like a tailor: measure how you need your brain to change and then find a plan that suits it. In The Tailored Brain, Emily Willingham explores the promises and limitations of well-known and emerging methods of brain customization, including prescription drugs, diets, and new research on the power of your “social brain.” Packed with real-life examples and checklists that allow readers to better understand their cognitive needs, this is the definitive guide to a better brain.
