Temperature regulation has witnessed many important developments in recent years. Body temperature is regulated by many internal and external influences. These include physiological and biochemical processes, climate, clothing, exercise, hibernation, diseases and pharmacological agents. This volume provides reviews of the latest research results and emerging themes in the field. Aspects discussed include fever, acute-phase immune response, cytokines, thermoregulatory peptides, neurophysiology, the neonate, mechanism of heat production, the role of brown adipose tissue, and ecological and behavioural thermoregulation. All research workers in the field of body temperature regulation, such as pharmacologists, physiologists, biochemists and biologists, will find this volume a valuable source of up-to-date information.
