The role of electrical signalling in the control of endocrine secretions by the brain has been clear for many years. Recently, the influences of hormones on synthetic events in neuroendocrine cells have raised new questions concerning the peptides released from such neurons. This volume concentrates on the relation between these two fields and asks how electrical action potentials facilitate secretion of substances from nerve cells which control endocrine events. While stimulus-secretion coupling has been studied extensively in other physiological contexts, this is the first treatment of the phenomenon in an exclusively neuroendocrine setting.

The Electrophysiology of Neuroendocrine Cells explores the role of electrical activity in neuroendocrine cells in stimulus-secretion coupling, sensory mechanisms, and intercellular communication. This comprehensive and concise handbook includes introductory material on the ontogenesis and classification of the neuroendocrine system and describes general electrical properties, voltage-gated ion channels, and the pharmacology of ion channels. By focusing on functional aspects, The Electrophysiology of Neuroendocrine Cells provides research scientists, physicians, and students with a basic understanding of neuroendocrine cells and their similarity to neurones, as well as their relationship to thyroid- or steroid-hormone secreting endocrine cells. The multidisciplinary nature of this book provides readers with a broad perspective on the electrical properties of neuroendocrine cells, and the combination of general information and specialized information makes the book accessible to beginning and advanced readers alike.
This volume contains a unique selection of chapters covering a wealth of contemporary topics in this ubiquitous and diverse system of cell signaling. It offers much more than the accessibility and authority of a primary text book, exploring topics ranging from the fundamental aspects of calcium signaling to its varied clinical implications. It presents comprehensive discussion of cutting-edge research alongside detailed analysis of critical issues, at the same time as setting out testable hypotheses that point the way to future scientific endeavors. The contributions feature material on theoretical and methodological topics as well as related subjects including mathematical modeling and simulations. They examine calcium signaling in a host of contexts, from mammalian cells to bacteria, fruit fly and zebrafish. With much of interest to newcomers to the field as well as seasoned experts, this new publication is both wide-ranging and authoritative. The chapter “Calcium Signaling: From Basic to Bedside” is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.
The skin, the body’s largest organ, is strategically located at the interface with the external environment where it detects, integrates and responds to a diverse range of stressors, including solar radiation. It has already been established that the skin is an important peripheral neuroendocrine-immune organ that is closely networked with central regulatory systems. These capabilities contribute to the maintenance of peripheral homeostasis. Specifically, epidermal and dermal cells produce and respond to classical stress neurotransmitters, neuropeptides and hormones, production which is stimulated by ultraviolet radiation (UVR), biological factors (infectious and non-infectious) and other physical and chemical agents. Examples of local biologically active products are cytokines, biogenic amines (catecholamines, histamine, serotonin and N-acetyl-serotonin), melatonin, acetylocholine, neuropeptides including pituitary (proopiomelanocortin-derived ACTH, b-endorphin or MSH peptides, thyroid stimulating hormone) and hypothalamic (corticotropin-releasing factor and related urocortins, thyroid-releasing hormone) hormones, as well as enkephalins and dynorphins, thyroid hormones, steroids (glucocorticoids, mineralocorticoids, sex hormones, 7-δ steroids), secosteroids, opioids and endocannabinoids. The production of these molecules is hierarchical, organized along the algorithms of classical neuroendocrine axes such as the hypothalamic pituitary adrenal axis (HPA), hypothalamic-thyroid axis (HPT), serotoninergic, melatoninergic, catecholaminergic, cholinergic, steroid/secosteroidogenic, opioid and endocannabinoid systems. Disruptions of these axes or of communication between them may lead to skin and/or systemic diseases. These local neuroendocrine networks also serve to limit the effect of noxious environmental agents to preserve local and consequently global homeostasis. Moreover, the skin-derived factors/systems can also activate cutaneous nerve endings to alert the brain to changes in the epidermal or dermal environments, or alternatively to activate other coordinating centers by direct (spinal cord) neurotransmission without brain involvement. Furthermore, rapid and reciprocal communications between epidermal and dermal and adnexal compartments are also mediated by neurotransmission including antidromic modes of conduction. Lastly, skin cells and the skin as an organ coordinate and/or regulate not only peripheral but also global homeostasis.
In this volume contemporary methods designed to provide insights into, mathematical structure for, and predictive inferences about neuroendocrine control mechanisms are presented.

In the years following publication of the DSM-5(R), the field of psychiatry has seen vigorous debate between the DSM's more traditional, diagnosis-oriented approach and the NIMH's more biological, dimension-based RDoC (research domain criteria) approach. Charney & Nestler's Neurobiology of Mental Illness is an authoritative foundation for translating information from the laboratory to clinical treatment, and its fifth edition extends beyond this reference function to acknowledge and examine the controversies, different camps, and thoughts on the future of psychiatric diagnosis. In this wider context, this book provides information from numerous levels of analysis, including molecular biology and genetics, cellular physiology, neuroanatomy, neuropharmacology, epidemiology, and behavior. Sections and chapters are edited and authored by experts at the top of their fields. No other book distills the basic science and underpinnings of mental disorders-and highlights practical clinical significance-to the scope and breadth of this classic text. In this edition, Section 1, which reviews the methods used to examine the biological basis of mental illness in animal and cell models and in humans, has been expanded to reflect critically important technical advances in complex genetics (including powerful sequencing technologies and related bioinformatics), epigenetics, stem cell biology, optogenetics, neural circuit functioning, cognitive neuroscience, and brain imaging. This range of established and emerging methodologies offer groundbreaking advances in our ability to study the brain as well as unique opportunities for the translation of preclinical and clinical research into badly needed breakthroughs in our therapeutic toolkit. Sections 2 through 7 cover the neurobiology and genetics of major psychiatric disorders: psychoses (including bipolar disorder), mood disorders, anxiety disorders, substance use disorders, dementias, and disorders of childhood onset. Also covered within these sections is a summary of current therapeutic approaches for these illnesses as well as the ways in which research advances are now guiding the search for new treatments. Each of these parts has been augmented in several different areas as a reflection of research progress. The last section, Section 8, reconfigured in this new edition, now focuses on diagnostic schemes for mental illness. This includes an overview of the unique challenges that remain in diagnosing these disorders given our still limited knowledge of disease etiology and pathophysiology. The section then provides reviews of DSM-5(R), which forms the basis of psychiatric diagnosis in the United States for all clinical work, and of RDoC, which provides an alternative perspective on diagnosis in heavy use in the research community. Also included are chapters on future efforts toward precision and computational psychiatry, which promise to someday align diagnosis with underlying biological abnormalities.
Stress has been recognized as an important factor in the development or recurrence of various mental disorders, from major depressive disorder to bipolar disorder to anxiety disorders. Stressful stimuli also appear to exert their effects by acting upon individuals with susceptible genotypes. Over the past 50 years, animal models have been developed to study these dynamic interactions between stressful stimuli and genetically susceptible individuals during prenatal and postnatal development and into adulthood. Stress and Mental Disorders: Insights from Animal Models begins with a discussion of the history of psychiatric diagnosis and the recent goal of moving toward precision psychiatry, followed by a review of clinical research on connections between stressful stimuli and the development of psychiatric disorders. Chapters are also included on neuroendocrine, immune, and brain systems involved in responses to stress. Additional chapters focus on the development of animal models in psychiatry and the susceptibility of the developing organism to stressful stimuli. Subsequent chapters are devoted to animal models of specific stress-sensitive psychiatric disorders, including schizophrenia, autism spectrum disorders, bipolar disorder, anxiety disorders, depression, and post-traumatic stress disorder. These chapters also focus on identification of promising molecular targets for development of new drug therapies. The section concludes with a chapter on animal models of resilience to stress-induced behavioral alterations as a newer approach to understanding why some animals are susceptible to stress and others are resilient, even though they are essentially genetically identical. The final chapter discusses how these basic laboratory studies are providing promising leads for future breakthroughs in the diagnosis, treatment, and prevention of mental disorders.
