Volume 14 provides the reader with a wide variety of perspectives on the enormous changes that have occurred in the study of food and fluid intake since the first edition of "Neurobiology of Food and Fluid Intake" published 14 years ago. As with the first edition, multiple viewpoints on issues of clinical significance and basic studies using laboratory animals are revealed, as world renowned experts in the field discuss homeostasis in various areas of alimentary behaviour and brain function. The text details the integration of the biological and behavioral contributions to homeostasis and the way in which basic neuroscientific studies of animal subjects can be used to illuminate parallel clinical phenomena in human subjects. Four retrospective essays on how the field has developed have been added to this new edition, and all chapters have been updated to integrate new material. New chapters in Volume 14 include motivation, food intake, body fluids, and an entirely new section on Reward, an important topic to cover in any study of motivated behaviour.
