Thirst is a subjective sensation, triggered by a lack of water and
accompanied by the desire to drink. As a powerful and compelling
sensation, it is perhaps only exceeded by the hunger for air and by
pain, and is central to any concern with the overall mechanisms of
homeostasis. Drinking is essential to the survival of most terrestrial
vertebrates, and provides a useful model system with which to analyse
the control of a complex type of behaviour. Furthermore, drinking
requires integrated behavioural responses to physiological stimuli and
environmental demands, and therefore offers a good example for the
analysis of the biological mechanisms underlying behaviour. First
published in 1982, this book describes the control of thirst and water
intake, and the physiology and psychology of drinking. Although this
book is intended primarily for students of psychology, physiology and
medicine, it should be of interest to all those concerned with the
scientific study of thirst and with the physiological and neural bases
of behaviour.
