Book excerpt: In the long history of the study of anatomy, neuroscience is a relatively new field, and there are plenty of mysteries yet to be uncovered. The Secret Life of the Brain explores the fascinating advances that have been made in the field so far, from the intricacies of memory and intelligence, to the enigmatic workings behind our sense of humour and our dreams. Full of illuminating illustrations and diagrams, this book lifts the lid on how drugs affect the brain; the science behind addiction; how the brain deals with trauma and pain; and the effects on the brain of love, age, and sex. Finally, you'll get a tantalising insight into the cutting-edge theories that are attempting to get behind the elements of neuroscience which we still can't quite explain.
