Neuroplasticity: 

The book explains how the brain is constantly reshaped by experience, learning, and environment—a concept once thought impossible. Costandi outlines how neuroplasticity works across life stages, from development to aging, and shows real examples such as stroke recovery, London cab drivers’ brain growth, and canaries learning new songs. He emphasizes that true “brain training” comes from meaningful activities like learning music or languages, not quick-fix apps. Clear and concise, it highlights how brain change defines our adaptability and humanity.
