The hypothalamus is the region of the brain in charge of the maintenance of the internal milieu of the organism. It is also essential to orchestrate reproductive, parental, aggressive-defensive, and other social behaviors, and for the expression of emotions. Due to the structural complexity of the hypothalamus, however, many basic aspects of its ontogenesis are still mysterious. Nowadays we assist to a renewal of interest spurred in part by the growing realization that prenatal and early postnatal influences on the hypothalamus could entail pathological conditions later in life. Intriguing questions for the future include: do early specification phenomena reflect on adult hypothalamic function and possibly on some kinds of behavior? Can early events like specification, migration or formation of nuclei influence adult hypothalamic function? A change in morphological paradigm, from earlier columnar interpretations to neuromeric ones, is taking place. Concepts long taken for granted start to be challenged in view of advances in developmental and comparative neurobiology, and notably also in the molecular characterization of hypothalamic structures. How should we understand the position of the hypothalamus in relation to other brain regions? Should we bundle it together with the thalamus, a functionally, genetically and developmentally very different structure? Does the classic concept of “diencephalon” make sense, or should the hypothalamus be separated? Does the preoptic area belong to the hypothalamus or the telencephalon? The answer to these questions in the context of recent causal molecular analysis will help to understand hypothalamic evolution and morphogenesis as well as its adult function and connectivity. In this Research Topic we have reviewed the fundamentals of hypothalamic ontogenesis and evolution, summarizing present-day knowledge, taking stock of the latest advances, and anticipating future challenges.

In this book, experts in the field discuss the latest research in developmental neuroendocrinology. Given that the hypothalamus is the center of neuroendocrine activity, the reader will learn about the molecular specification of hypothalamic cells, developmental modulators and epigenetic factors influencing hypothalamic development, and the development of neuroendocrine circuits. Each chapter provides a concise review of the current and future perspectives in developmental neuroendocrinology. Important insights into state-of-the-art techniques applied to functional circuit tracking, lineage tracing of hypothalamic cells, and the identification of genes altered through epigenetic mechanisms are also provided. Given its scope, the book will appeal to all students and researchers who are eager to understand the processes involved in hypothalamus development and the establishment of neuroendocrine circuits. This is the ninth volume in the International Neuroendocrine Federation (INF) Masterclass in Neuroendocrinology series* that aims to illustrate highest standards and encourage the use of the latest technologies in basic and clinical research and hopes to provide inspiration for further exploration into the exciting field of neuroendocrinology. *Volumes 1-7 published by Wiley.

How hormonal signals in one small structure of the brain—the hypothalamus—govern our physiology and behavior. As human beings, we prefer to think of ourselves as reasonable. But how much of what we do is really governed by reason? In this book, Gareth Leng considers the extent to which one small structure of the neuroendocrine brain—the hypothalamus—influences what we do, how we love, and who we are. The hypothalamus contains a large variety of neurons. These communicate not only through neurotransmitters, but also through peptide signals that act as hormones within the brain. While neurotransmitter signals tend to be ephemeral and confined by anatomical connectivity, the hormone signals that hypothalamic neurons generate are potent, wide-reaching, and long-lasting. Leng explores the evolutionary origins of these remarkable neurons, and where the receptors for their hormone signals are found in the brain. By asking how the hypothalamic neurons and their receptors are regulated, he explores how the hypothalamus links our passions with our reason. The Heart of the Brain shows in an accessible way how this very small structure is very much at the heart of what makes us human.

How we raise young children is one of today's most highly personalized and sharply politicized issues, in part because each of us can claim some level of "expertise." The debate has intensified as discoveries about our development-in the womb and in the first months and years-have reached the popular media. How can we use our burgeoning knowledge to assure the well-being of all young children, for their own sake as well as for the sake of our nation? Drawing from new findings, this book presents important conclusions about nature-versus-nurture, the impact of being born into a working family, the effect of politics on programs for children, the costs and benefits of intervention, and other issues. The committee issues a series of challenges to decision makers regarding the quality of child care, issues of racial and ethnic diversity, the integration of children's cognitive and emotional development, and more. Authoritative yet accessible, From Neurons to Neighborhoods presents the evidence about "brain wiring" and how kids learn to speak, think, and regulate their behavior. It examines the effect of the climate-family, child care, community-within which the child grows.

In the decade before the publication of this study, melanocortin biology matured. Three additional receptors were discovered, and animal models were established addressing the function of each receptor. Researchers now know that the diverse physiologic responses to melanocortins - including their role in development, weight and endocrine regulation, cortisol production, secretion from exocrine glands, and pigmentation - can be defined in terms of individual receptors. In this text, contributors from the field of evolutionary biology, peptide chemistry, pigmentation biology, neuroscience, endocrinology and genetics provide the reader with a comprehensive review of melanocortin biology. Six areas of active research are addressed: peptide and small molecule chemistry; receptor structure and function; energy homeostasis; pigmentation; adrenocorticol function; and behaviour. There are 56 papers and 20 posters altogether, taken from the Fifth Melanocortin Meeting, held in 2002.

This revised new edition reviews the substantial advances in our understanding of the vital role of growth hormone (GH) in maintaining adult health, and the resulting disorders from GH deficiency. The first edition, published in 1996, provided a pioneering overview of the subject; this new edition provides an even more comprehensive account, fully updated with the latest research, clinical applications, and references. The therapeutic benefits of GH treatment in GH deficiency are thoroughly evaluated, including effects on metabolism, cardiac function, exercise performance, psychosocial aspects, and aging and gender-specific effects. This compilation by the world's leading experts covers clinical investigation, diagnosis and treatment issues, and encompasses new knowledge of the control and action of GH secretion. This volume is the most authoritative, comprehensive, and detailed account available and will be an essential source of reference for all endocrinologists.
