Anti-social behaviors and social deficits induced mental disorders are critical problems in our society today. Social behaviors and interactions are shaped by experience, hereditary components (genes, hormones and neuropeptides) and environmental factors (photoperiods and metabolic signals). In addition to the classical gonadotropin-releasing hormone, RFamide peptides, kisspeptin and gonadotropin-inhibiting hormone are emerging as important regulators of the reproductive axis. These neuropeptides are evolutionarily conserved and are regulated by environmental factors. In this Research Topic, we advocate more recent advances in reproductive neuropeptides and sex steroids in the domains of social behavior including sexual and parental behavior, aggression, stress and anxiety. Using multiple species model, we also review how genes and the neuroendocrine system interact at the cell and organismic levels to contribute to social behavior in particular the epigenetic genomic changes caused by early life environment. We provide comprehensive insights of distinct neural networks and how cellular and molecular events in the brain regulate social behavior from a comparative perspective.

This book concentrates on two major topics: firstly, the molecular and neural biology of hormone actions relevant to normal social behaviors; and secondly, the clinical treatment of human patients in whom these behaviors have gone wrong.

The subject of this book is neuroendocrinology, that branch of biological science devoted to the interactions between the two major integrative organ systems of animals-the endocrine and nervous systems. Although this science today reflects a fusion of endocrinology and neurobiology, this synthetic ap proach is relatively recent. At the beginning of the 20th century, when the British physiologists, Bayliss and Starling, first proposed endocrinology to be an independent field of inquiry, they went to great lengths to establish the autonomy of chemical secretions in general and their independence from nervous control in particular (Bayliss, W. M. , and Starling, E. H. , 1902, The mechanism of pancreatic secretion,]. Physiol. 28:325). They argued with Pav lov, who said that there was a strong influence of the nervous system on the gastrointestinal phenomena the endocrinologists were studying. For several decades, the English physiologists prevailed, at least in the West; and Pavlov's critique was not taken to heart by the practitioners of the newly emerging discipline of endocrinology. Through the work of Harris, the Scharrers, Sawyer, Everett, and others, there has been something of a scientific detente in the latter half of this century; the hybrid field of neuroendocrinology is now regarded as one of the corner stones of modern neural science and is of fundamental importance in basic and clinical endocrinology.

In social relationshipsÑwhether between mates, parents and offspring, or friendsÑwe find much of lifeÕs meaning. But in these relationships, so critical to our well-being, might we also detect the workings, even directives, of biology? This book, a rare melding of human and animal research and theoretical and empirical science, ventures into the most interesting realms of behavioral biology to examine the intimate role of endocrinology in social relationships. The importance of hormones to reproductive behaviorÑfrom breeding cycles to male sexual displayÑis well known. What this book considers is the increasing evidence that hormones are just as important to social behavior. Peter Ellison and Peter Gray include the latest findingsÑboth practical and theoreticalÑon the hormonal component of both casual interactions and fundamental bonds. The contributors, senior scholars and rising scientists whose work is shaping the field, go beyond the proximate mechanics of neuroendocrine physiology to integrate behavioral endocrinology with areas such as reproductive ecology and life history theory. Ranging broadly across taxa, from birds and rodents to primates, the volume pays particular attention to human endocrinology and social relationships, a focus largely missing from most works of behavioral endocrinology.

The communication between the hypothalamus, pituitary, and gonad is bi-directional, and alterations of the communication in the circuitry, as often occurs during aging and drug abuse, results in acyclicity, hypogonadism, and impotence. This important reference covers topics on the neuroendocrine control mechanisms governing the reproductive process in both males and females. It discusses the importance of the differentiation of the neuroendocrine brain during the developmental period for the normal reproductive process. It also summarizes the effects of prenatal drug abuse on the differentiation of the neuroendocrine brain development and how this alteration induces abnormalities in the reproduction process. This comprehensive volume compares the effects of various psycoactive drugs on the maintenance of reproduction and describes the changes in the reproductive neurendocrine axis during aging.

Historically, reproductive science has focused on reproductive behaviors divorced from the contexts in which they occur. Taking a more integrated view, this book explores the neuroendocrine bases of reproduction in relation to their environmental and social contexts. The contributors provide compelling accounts of reproductive behaviors in animals ranging from turtles and lizards to humans and nonhuman primates. They examine these behaviors from the perspectives of ethology, endocrinology, behavioral genetics, and evolutionary ecology. Together, they illuminate the dynamic interplay between the ecological and social contexts of a species and the biological mechanisms regulating reproductive behavior. The book shows how an appreciation of the full complexity of the context of reproduction actually simplifies and clarifies our understanding of reproductive behavior. Contributors: Gregory F.

This special volume provides twelve contributions that discuss different aspects of social and endocrine behaviors with an emphasis on the neural regulation of these behaviors. In addition, several review chapters address the neural plasticity that results from exposure to hormones or the experiences with the behavior. Finally, each of the contributions emphasizes future directions and incorporation of newly developed neuroscience techniques and approaches.

The Routledge International Handbook of Social Neuroendocrinology is an authoritative reference work providing a balanced overview of current scholarship spanning the full breadth of the rapidly developing field of social neuroendocrinology. Considering the relationships between hormones, the brain, and social behavior, this collection brings together groundbreaking research in the field for the first time. Featuring 39 chapters written by leading researchers, the handbook offers impressive breadth of coverage. It begins with an overview of the history of social neuroendocrinology before discussing its methodological foundations and challenges. Other topics covered include state-of-the-art research on dominance and aggression; social affiliation; reproduction and pair bonding (e.g., sexual behavior, sexual orientation, romantic relationships); pregnancy and parenting; stress and emotion; cognition and decision making; social development; and mental and physical health. The handbook adopts a lifespan approach to the study of social neuroendocrinology throughout, covering the role that hormones play during gestation, childhood, adolescence, and adulthood. It also illustrates the evolutionary forces that have shaped hormone-behavior associations across species, including research on humans, non-human primates, birds, and rodents. The handbook will serve as an authoritative reference work for researchers, students, and others intrigued by this topic, while also inspiring new lines of research on interactions among hormones, brain, and behavior in social contexts.
