ABSTRACT: Questions regarding the role of angiotensin (Ang) were examined in mice. In contrast to rats, CD-1 male mice failed to drink water or sodium after exogenous Ang injection. Fos-IR in these mice was prevalent in the subfornical organ (SFO) and there were no differences in Fos-IR among different strains or gender of mice. Like rats, mice drank both sodium and water after furosemide treatment. Mice given furosemide were also hypovolemic (increased plasma protein and hematocrit ratios) and had increased plasma renin activity (PRA). Fos-IR in these mice was similar to that seen after exogenous Ang treatment. Whereas rats drink both sodium and water after polyethylene glycol treatment, mice did not show a clear sodium appetite. However, these mice were hypovolemic, had increased PRA, had modestly increased aldosterone, and drank water. Fos-IR was prevalent in almost all brain regions examined after this treatment. Thus, our results revealed several differences between rats and mice with regard to responses after procedures that mimic the renin-angiotensin-system (RAS).

Thirst and Sodium Appetite: Physiological Basis describes the phenomenon of thirst and the mechanisms that define the need for water. Thirst and appetite has generated much study and research about the physiological, endocrinological, and pharmacological mechanisms that influence water intake. However, in this book, other concerns have been emphasized, such as the significance of brain mechanisms in the subject matter. This book, consisting of 11 chapters, starts with a basic description of thirst then to an analysis of basic physiological mechanisms that determine water intake. Another topic also discussed in this book is various experimental paradigms that resulted to the dual-depletion theory of thirst. The neuroanatomical, neuroendocrinological, and neuropharmacological brain mechanisms are covered in three chapters of this book. These brain mechanisms respond to different peripheral signals that stimulate the thirst. The final chapters are dedicated to sodium appetite. Although it has lesser literature than thirst has, there have been significant developments in the understanding of the role of sodium appetite in extracellular thirst. The last chapter reviews the questions that has kept investigators at bay and recommends direction of where future research may go.

The behavioral neuroscience of thirst and sodium appetite are research ventures that have expanded dramatically in recent years. Work done in the mid-1950s and early 1960s made it clear that drinking behavior could be affected by direct manipulations of the brain, especially by brain damage and by pharmacological treat ments. Since that. time experimental approaches have diversified and the research enterprise has attracted the interest of a broad international community of scientists. Many aspects of both thirst and sodium appetite are being studied. The most prominent of these are: 1) phylogenetic and ontogenetic aspects of the phenomena of drink ing behavior, 2) the mechanisms of a variety of dipsogenic and antidipsogenic treatments, both drugs and hormones, 3) the biological controls of drinking and their interaction with the regulation of blood volume and blood pressure, 4) the peripheral signals of drinking including the role of the baro- and volume-receptors, 5) the receptor systems within the brain and the neuroanatomical circuitry for thirst and sodium appetite, and 6) the possible roles of brain sodium and of the hormones of sodium conservation ln the arousal of sodium appetite. This acceleration of basic research activity has given in sights into the clinical disorders of thirst and salt appetite and has produced pharmacological agents of potential therapeutic use.

A timely symposium entitled Body-Fluid Homeostasis: Transduction and Integration was held at Araraquara, São Paulo, Brazil in 2011. This meeting was convened as an official satellite of a joint gathering of the International Society for Autonomic Neuroscience (ISAN) and the American Autonomic Society (AAS) held in Buzios, Rio de Janeiro. Broad international participation at this event generated stimulating discussion among the invited speakers, leading to the publication of Neurobiology of Body Fluid Homeostasis: Transduction and Integration. Drawn from the proceedings and filled with rich examples of integrative neurobiology and regulatory physiology, this volume: Provides updated research using human and animal models for the control of bodily fluids, thirst, and salt appetite Explores neural and endocrine control of body fluid balance, arterial pressure, thermoregulation, and ingestive behavior Discusses recent developments in molecular genetics, cell biology, and behavioral plasticity Reviews key aspects of brain serotonin and steroid and peptide control of fluid consumption and arterial pressure The book highlights research conducted by leading scientists on signal transduction and sensory afferent mechanisms, molecular genetics, perinatal and adult long-term influences on regulation, central neural integrative circuitry, and autonomic/neuroendocrine effector systems. The findings discussed by the learned contributors are relevant for a basic understanding of disorders such as heat injury, hypertension, and excess salt intake. A unique reference on the neurobiology of body fluid homeostasis, this volume is certain to fuel additional research and stimulate further debate on the topic.

The second volume of the Handbook does not parallel any volume of the first edition; it is one more sign, or reflection, of the expansion of the field. By emphasizing the experimental approach, it illustrates the tools that have re cently become available for investigating the nervous system. Also, perhaps even more than other volumes, it illustrates the multidisciplinary nature of the field, requiring multidisciplinary methodology. It is now recognized that the availability of methodology is often the rate-limiting determinant of studies and that improvements or innovations in instrumentation can open up new avenues. A new improved method, although opening up new possibilities and being crucial to making advances, is only a tool whose use will determine its use fulness. If we do not recognize its possibilities, its use will be limited; if we do not recognize its limitations, it will mislead us. It is the possibilities and limitations and the results obtained that are illustrated here.

The hunger for sodium has been used as a model system in which to study how the brain produces motivated behaviour. In this account of the field Jay Schulkin draws together information across a range of disciplines and topics, ranging from the ecology of salt ingestion to the sodium molecule and the action of various hormones. The phenomenon of sodium hunger was discovered by Curt Richter, the great American psychobiologist, over 50 years ago. Its study has been of interest for some time: to naturalists, psychologists, endocrinologists, physiologists and neuroscientists. This book offers a systematic account of the behaviour of the sodium hungry animal, the endocrine and physiological mechanisms that act to maintain sodium balance and then act on the brain to promote the search for and the ingestion of salt. Finally, the book provides a description of a neural network that orchestrates the behaviour of salt seeking and salt ingestion. Graduate students and research workers in psychology, physiology and neuroscience will find valuable information in this review.

This series of concise essays on Enteroceptors is designed to interest the gradu ate student and to stimulate research. Even before the advent of electrophysiological studies, classical physiological techniques had shown the essence of the role of many of the enteroceptors. Thus the monitoring influence of the cardiovascular mechanoreceptors on the heart and on the systemic vascular resistance, the role of the arterial chemoreceptors in hypoxia and the influence of the so-called Hering Breuer stretch receptors on breathing had all been documented. The pioneering work of ADRIAN, BRONK, ZOTTERMAN and others using electroneurographic methods gave a remarkable impetus to the study of the enteroceptors themselves. Nowhere is this better exemplificd than in the case of the afferent end organs of the heart, the respiratory tract and the abdominal and pelvic viscera. The remarkable development of our knowledge of the multiplicity of types of nerve endings from the thoracic and abdominal viscera acquired from electrophysiological studies has refocussed our attention on the histological details of the sites of such receptors. Once more research on the structural side has been accelerated by the question raised by evidence obtained from functional studies. This is well illustrated in the case of the carotid body, where the long cherished belief that the innervated epithelioid cells constitute the chemoreceptor complex is now under attack. The detailed consideration of the functional characteristics of each entero ceptor considered has not occupied our whole attention.
