Book Description
Recently, several pioneering discoveries have identified new roles of stress and steroid hormones in modulating CNS functions. Specifically, glucocorticoids, mineralocorticoids, sex hormones and neurosteroids have been shown to affect synaptic receptors and ion channels and therefore regulate in a complex manner physiological processes ranging from homeostatic to cognitive functions. Likewise, in some disorders of the nervous system, steroid hormones have been shown to play different roles: either favoring or combating the disease process. In this Frontier Research Topic, we have put together leaders in the field to provide novel opinions on the effects of steroid hormones on synaptic transmission and plasticity from ion channels to pathophysiological processes. We expect critical reviews of the work that has been conducted recently in this area and enrich these discussions with the novel, exciting new findings.

Book Description
GABA is the principal inhibitory neurotransmitter in the CNS and acts via GABAA and GABAB receptors. Recently, a novel form of GABAA receptor-mediated inhibition, termed “tonic” inhibition, has been described. Whereas synaptic GABAA receptors underlie classical “phasic” GABAA receptor-mediated inhibition (inhibitory postsynaptic currents), tonic GABAA receptor-mediated inhibition results from the activation of extrasynaptic receptors by low concentrations of ambient GABA. Extrasynaptic GABAA receptors are composed of receptor subunits that convey biophysical properties ideally suited to the generation of persistent inhibition and are pharmacologically and functionally distinct from their synaptic counterparts. This book highlights ongoing work examining the properties of recombinant and native extrasynaptic GABAA receptors and their preferential targeting by endogenous and clinically relevant agents. In addition, it emphasizes the important role of extrasynaptic GABAA receptors in GABAergic inhibition throughout the CNS and identifies them as a major player in both physiological and pathophysiological processes.

Book Description
The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

Book Description
The hypothalamic-pituitary-adrenal axis controls reactions to stress and regulates various body processes such as digestion, the immune system, mood and sexuality, and energy usage. This volume focuses on the role it plays in the immune system and provides substantive experimental and clinical data to support current understanding in the field, and potential applications of this knowledge in the treatment of disease. * Evidence presented in this book suggests that the nervous, endocrine, and immune systems form the Neuroendoimmune Supersystem, which integrates all the biological functions of higher organisms both in health and disease for their entire life cycle. * Contributors include both the scientists who initiated the work on the HPA axis and on the autonomic nervous system, and those who joined the field later.

Book Description
A comprehensive, multidisciplinary review, Neural Plasticity and Memory: From Genes to Brain Imaging provides an in-depth, up-to-date analysis of the study of the neurobiology of memory. Leading specialists share their scientific experience in the field, covering a wide range of topics where molecular, genetic, behavioral, and brain imaging techniques have been used to investigate how cellular and brain circuits may be modified by experience. In each chapter, researchers present findings and explain their innovative methodologies. The book begins by introducing key issues and providing a historical overview of the field of memory consolidation. The following chapters review the putative genetic and molecular mechanisms of cell plasticity, elaborating on how experience could induce gene and protein expression and describing their role in synaptic plasticity underlying memory formation. They explore how putative modifications of brain circuits and synaptic elements through experience can become relatively permanent and hence improve brain function. Interdisciplinary reviews focus on how nerve cell circuitry, molecular expression, neurotransmitter release, and electrical activity are modified during the acquisition and consolidation of long-term memory. The book also covers receptor activation/deactivation by different neurotransmitters that enable the intracellular activation of second messengers during memory formation. It concludes with a summary of current research on the modulation and regulation that different neurotransmitters and stress hormones have on formation and consolidation of memory.

Book Description
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.
