Tricky concepts are illustrated and explained with clarity and precision, as The Human Brain Book looks at how the brain sends messages to the rest of the body, how we think and feel, how we perform unconscious actions (for example breathing), explores the nature of genius, asks why we behave the way we do, explains how we see and hear things, and how and why we dream. Physical and psychological disorders affecting the brain and nervous system are clearly illustrated and summarized in easy-to-understand terms.

The unique DVD brings the subject to life with interactive elements. These include a clickable model of the brain's structure that allows the user to zoom in and discover deeper layers of detail, while complex processes, such as the journey of a nerve impulse, are broken down and simplified through intuitive animations.
