Sleep is the subject of intense scientific debate among biologists and neuroscientists. Why must we spend about one-third of our lives asleep? What exactly is sleep? Why does a lack of sleep impair our cognitive abilities and leave us vulnerable to a host of medical issues ranging from obesity to reduced resistance to infectious disease?

One of the most complicated and advanced computers on Earth can't be purchased in any store. This astonishing device, responsible for storing and retrieving vast quantities of information that can be accessed at a moment's notice, is the human brain. How does such a dynamic and powerful machine make memories, learn a language, and remember how to drive a car? What habits can we adopt in order to learn more effectively throughout our lives? The answers to these questions are merely the tip of the iceberg in The Learning Brain.

After all, we are all human. In Understanding the Dark Side of Human Nature, Professor Daniel Breyer takes us on a fascinating philosophical journey into many of the deepest and darkest questions that have engaged humanity for millennia.

Your nervous system is you. All the thoughts, perceptions, moods, passions, and dreams that make you an active, sentient being are the work of this amazing network of cells. For many centuries, people knew this was true. But no one was sure how it happened.
