It’s no secret that the human brain is a marvellous thing. From the movements you rely on every day to the emotions you express, the dreams that feel real and the thoughts that whizz through your mind, the brain controls it all. Centuries of study have yielded many answers to its countless mysteries. We know about the synapses and neurons that make up the brain, and leading surgeons can now map someone’s brain and perform once impossible operations. But there is still so much that we don’t understand. What does it really mean to be conscious? Why do we have cognitive biases when the facts contradict us? And why are some people psychopaths who see the world in a totally different way? In this book you’ll explore some of the answers to these questions, chart the life of a pioneering neurosurgeon and relive some of the most bizarre experiments ever conducted in the endless quest to understand the brain.
