Where in the brain would you find the hippocampus and what is its function? What happens in the brain when we laugh? What's the checklist for assessing the severity of a brain injury? And how is Alzheimer's different from other dementias? In this accessible and fascinating book, readers will learn the answers to these questions and many more. How The Brain Works takes the reader from the physiology of the brain through to its processes – such as what happens in the brain while we sleep – and on to traumas, diseases and psychological conditions.
