The human brain is an amazing organ, but it is also very complex. So how does it control everything that we do and feel? How does it change as we get older? And what happens when it goes wrong? We now know the answers to some of these questions, but others are still a mystery.

In this book, you'll read about people who changed the history of neuroscience. You'll discover some amazing facts about science, technology, engineering, and maths (STEM). You'll also be able to test your own brain and learn surprising things about yourself!
