Masterclass in Neuroendocrinology – serie

How do electrical activity and calcium signals in neurons influence the secretion of peptide hormones? This volume presents the current state of knowledge regarding the electrical, calcium signaling and synaptic properties of neuroendocrine systems from both vertebrate and invertebrate systems. The contributions span in vivo and in vitro studies that address: state‐dependent plasticity, relevance of firing patterns, membrane properties, calcium flux (including dynamic imaging and homeostasis), and molecular mechanisms of exocytosis, including from non-neuronal secretory cells. The chapters focus not only on research results but also on how experiments are conducted using state-of-the-art techniques, and how the resulting data are interpreted.While there are many books on the secretory properties of neurons, this is the first to focus on the distinctive secretory properties of neuroendocrine neurons. Accordingly, it offers an important text for undergraduate and graduate neuroscience students, and will also appeal to established scientists and postdoctoral fellows. This is the eighth volume in the Masterclass in Neuroendocrinology series* - now a co-publication between Springer Nature and the INF (International Neuroendocrine Federation). *Volumes 1-7 published by Wiley

This book explores how daily and seasonal rhythmicity is generated, how these rhythms are synchronised by our environment, and how they regulate the neuroendocrine systems that impact our physiology and behaviour.The constraints of surviving in a seasonal environment have shaped human evolution and migration, have shaped our societies and cultures, and continue to influence our everyday lives, health and wellbeing.  Identifying the mechanisms whereby seasonal rhythmicity is generated and regulates the brain and body is not only important for understanding the natural world and relevant to animal production, it also offers many insights into the human condition. Each chapter is written by an international expert in the field of chronobiology. A historical perspective on how research into photoperiodism and rhythmicity progressed is initially provided, but the main focus of this book is on the remarkable studies in the last few decades that have unravelled the molecular and cellular machinery underpinning circadian and circannual timing. Topics covered include the role of melatonin in communicating seasonal information to the brain and pituitary gland, the neuroanatomical pathways in mammals, birds and fish by which changes in photoperiod reach the hypothalamus, the role of glial cells (tanycytes) and thyroid hormone in seasonal rhythmicity, neuroplasticity across seasons, effects of changing day length on mood, regulation of “clock“ gene expression, and the role of the suprachiasmatic nucleus. This book will appeal to all students and researchers who wish to learn about current and past research on daily and seasonal rhythmicity.This is the tenth volume in the International Neuroendocrine Federation (INF) Masterclass in Neuroendocrinology series (Volumes 1-7 published by Wiley) that aims to illustrate highest standards and encourage the use of the latest technologies in basic and clinical research and hopes toprovide inspiration for further exploration into the exciting field of neuroendocrinology.

This volume highlights current research on how the neuroendocrine system helps to influence emotional states and ultimately behavioral output.Social relationships and context-appropriate behavioral responses are important for the survival of most vertebrate species. These relationships can range from transient social interactions to strong social bonding between sexual partners and social behaviors can be observed and evaluated from the individual- to the group-level. Further, behavioral output is shaped by complex interactions between the physical environment, genetics, experience, and context, and are often modulated by the neuroendocrine system. In this book, experts in the field will provide a sweeping look at novel research in the neuroendocrine regulation of important behaviors ranging from parental care to social homeostasis, with a focus on comparative studies across vertebrate species. The first part of the book is dedicated to theneuroendocrinology of relationships, including the coordination of acoustic signals in songbirds, the complexity of social relationships in primates, and cooperation and parenting in humans. The second part of the book focuses on social behaviors and provides some insights into their regulation, including the neuroendocrine regulation of maternal behavior in rodents, the roles of oxytocin and vasopressin in the modulation of sex-specific social behavior, the interactions between adult neurogenesis, the neuroendocrine system and social behavior, and a consideration of neuroendocrine influences on reproductive decision making across species. The book concludes with a section on environmental influences on neuroendocrine systems underlying behavior, including how social isolation and endocrine disrupting chemicals affect the neuroendocrinology of behavior and emotions.Given its breadth, this volume is appropriate for undergraduate students, graduate students, postdoctoral researchers, and established researchers who are interested in neuroendocrinology and behavior.This is the sixteenth volume in the International Neuroendocrine Federation (INF) Masterclass in Neuroendocrinology series, which aims to illustrate the highest standards and highlight the latest technologies in basic and clinical research and aspires to provide inspiration for further exploration into the exciting field of neuroendocrinology.

Adaptations to maternal physiology are required for a successful pregnancy outcome. These changes are primarily orchestrated by the mother’s brain and involve multiple neuroendocrine systems. For this book, the editors have gathered internationally recognized experts who have contributed to the major advances in our understanding of different aspects of the neuroendocrine regulation of mammalian pregnancy and lactation.The book begins with a discussion of how pregnancy is recognized and maintained and the role of the placental hormones in supporting key adaptations required for a successful pregnancy. The next few chapters focus on the neuroendocrine adaptations that occur during pregnancy in some key regulatory processes to ensure a sufficient supply of energy and nutrients, protect the fetus from potentially harmful maternal stress hormones, and prepare mammals for birth, milk production, lactation and motherhood. Finally, our current understanding of how the significant peripartum hormonal changes contribute to the mother’s cognitive function and mood is examined. This book provides a broad overview of the finely orchestrated neuroendocrine adaptations that occur in pregnancy and lactation and discusses how such changes contribute to maximizing the likelihood of a positive outcome for mother and infant. Importantly the evidence for involvement of neuroendocrine dysregulation in some pregnancy-related complications, such as preterm birth and perinatal mood disorders is also highlighted. In addition to addressing fundamental mechanisms in the regulation of mammalian pregnancy and lactation, the book includes the most recent advances in the field made possible by utilizing the latest innovative research technologies. Moreover, it provides opinions on optimal experimental approaches, relates findings from experimental animal models with those from humans, and outlines the direction and opportunities for future research in this arena. It is an essential resource for undergraduate students, postgraduate students, and early career researchers embarking upon their journey in the fields of neuroendocrinology, endocrinology, reproductive biology or behavioural neuroscience. It also provides a valuable synopsis for established neuroendocrine researchers and educators, especially those whose interest transcends the nexus between neuroendocrinology and reproductive biology. This is the 15th volume in the International Neuroendocrine Federation (INF) “Masterclass in Neuroendocrinology” series, which aims to illustrate the highest standards and to encourage the use of the latest technologies in basic research and hopes to provide inspiration for further exploration into the exciting field of neuroendocrinology.
