GABA (gamma-aminobutyric acid) is the main neurotransmitter regulating sleep. The majority of drugs presently in use for the treatment of sleep disorders act by enhancing GABAergic neuronal inhibition. The GABA system is, therefore, of prime clinical relevance for the therapy of insomnia. The focus of this volume is on the neuropsychopharmacology and the clinical impact of the GABA system in regulating sleep and wakefulness. It presents molecular, neuropharmacological, systems-biological and clinical approaches to the understanding of the mechanism of action of GABA and GABAergic drugs. It also explores the role of GABA in the basic drives that affect sleep, and the influences that adapt sleep and wakefulness to external events.

A review of the current state of the clinical and basic science of the pharmacology of sleep. The information provided ranges from a historical perspective to current concepts of sleep mechanisms, including the interaction between pharmacology and sleep-wake regulation and between chronopahrmacology and sleep-wake rhythms. For the first time in one single volume, both the basic mechanisms of sleep, and the basic and clinical aspects of the pharmacology of sleep are dealt with in a thorough, comprehensive and authoritative manner. The chapters, written by the foremost scientific authorities in this field, integrate the latest information on the basic mechanisms of drugs as they relate to their effects on sleep.

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.

It’s remarkable how much the foods we eat can impact our brain chemistry and emotions. What and when we eat can make the difference between feeling anxious and staying calm and in control. But most of us don’t realize how much our diets influence our moods, thoughts, and feelings until we make a change. In The Antianxiety Food Solution, you’ll find four unique antianxiety diets designed to help you address nutritional deficiencies that may be at the root of your anxiety and enjoy the many foods that foster increased emotional balance. This helpful guide allows you to choose the best plan for you and incorporates effective anxiety-busting foods and nutrients. You’ll soon be on the path to freeing yourself from anxiety—and enjoying an improved overall mood, better sleep, fewer cravings, and optimal health—the natural way! The book also includes an easy-to-use index. In The Antianxiety Food Solution, you’ll discover: How to assess your diet for anxiety-causing and anxiety-calming foods and nutrients Foods and nutrients that balance your brain chemistry Which anxiety-triggering foods and drinks you may need to avoid Easy lifestyle changes that reduce anxiety and increase happiness

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.
