For modern scientists, history often starts with last week's journals and is regarded as largely a quaint interest compared with the advances of today. However, this book makes the case that, measured by major advances, the greatest decade in the history of brain studies was mid-twentieth century, especially the 1950s. The first to focus on worldwide contributions in this period, the book ranges through dozens of astonishing discoveries at all levels of the brain, from DNA (Watson and Crick), through growth factors (Hamburger and Levi-Montalcini), excitability (Hodgkin and Huxley), synapses (Katz and Eccles), dopamine and Parkinson's (Carlsson), visual processing (Hartline and Kuffler), the cortical column (Mountcastle), reticular activating system (Morruzzi and Magoun) and REM sleep (Aserinsky), to stress (Selye), learning (Hebb) and memory (HM and Milner). The clinical fields are also covered, from Cushing and Penfield, psychosurgery and brain energy metabolism (Kety), to most of the major psychoactive drugs in use today (beginning with Delay and Deniker), and much more.

This updated text will continue to serve the needs of students in introductory neuroscience courses. Among topics highlighted in the 3rd edition are the superfamily of molecules responsible for membrane signalling, and the molecular basis of sensory perception.

Leading neuroscientist Gordon M. Shepherd embarks on a paradigm-shifting trip through the "human brain flavor system," laying the foundations for a new scientific field: neurogastronomy. Challenging the belief that the sense of smell diminished during human evolution, Shepherd argues that this sense, which constitutes the main component of flavor, is far more powerful and essential than previously believed. Shepherd begins Neurogastronomy with the mechanics of smell, particularly the way it stimulates the nose from the back of the mouth. As we eat, the brain conceptualizes smells as spatial patterns, and from these and the other senses it constructs the perception of flavor. Shepherd then considers the impact of the flavor system on contemporary social, behavioral, and medical issues. He analyzes flavor's engagement with the brain regions that control emotion, food preferences, and cravings, and he even devotes a section to food's role in drug addiction and, building on Marcel Proust's iconic tale of the madeleine, its ability to evoke deep memories. Shepherd connects his research to trends in nutrition, dieting, and obesity, especially the challenges that many face in eating healthily. He concludes with human perceptions of smell and flavor and their relationship to the neural basis of consciousness. Everyone from casual diners and ardent foodies to wine critics, chefs, scholars, and researchers will delight in Shepherd's fascinating, scientific-gastronomic adventures. - Publisher.
