Book Description
Narcolepsy is a disabling sleep disorder that is characterized by persistent sleepiness, and cataplexy -- an involuntary loss of waking muscle tone. Cataplexy and narcolepsy are caused by the loss of hypocretin containing neurons in the hypothalamus. However, it is hypothesized that dopamine is also involved in sleep and motor control and plays a role in cataplexy. This study investigated how manipulating dopamine affected sleep and cataplexy in narcoleptic mice devoid of hypocretin. We used d-amphetamine to increase endogenous dopamine levels and quinpirole (D2 agonist) to agonize D2 receptor sites. Amphetamine promoted wakefulness while decreasing sleep in wild-type mice, but was less effective in narcoleptic mice. Amphetamine also reduced cataplexy as well as sleep attacks (an indicator of sleepiness) in narcoleptic mice. Quinpirole had no effect on sleep or wakefulness; however, it potently increased cataplexy without affecting sleep attacks in narcoleptic mice.

Book Description
The orexin system, discovered in 1998, has emerged as a crucial player in regulating the sleep and wake balance inside our brain. This discovery has sparked a burst of novel and dynamic research on the physiology and pathology of sleep. The Orexin System: Basic Science and Role in Sleep Pathology honors this research and the authors share their ideas and perspectives on the novel developments within the field. The book examines the intricate role of the orexin system in regulating sleep and wake, and its interaction with other wake-regulating systems. The orexin system is dissected at the cellular and molecular level to explore the diversity of the orexin-producing neurons, their projections, and their signaling pathways. Additionally, the book discusses the diseases which are associated with a dysfunctional orexin system, such as narcolepsy, insomnia, substance abuse, and Alzheimer’s disease, and explores the new potential therapeutic applications derived from the burst of research around this fascinating system. This publication is essential reading for neurobiologists, neurologists, psychopharmacologists, sleep researchers, and other researchers and clinical scientists interested in sleep, sleep research, insomnia, and medicine in general.

Book Description
Narcolepsy serves as a prototype of how the interaction of high quality clinical research and groundbreaking basic science can collaborate to defne the cause of a disease and change forever how we evaluate and treat it. There is scarcely a topic in this book that would have been covered in the same way 10 years ago as it is d- cussed today. We are also fortunate that many of the players in this dramatic tu- around have contributed to this volume, so that the result is a tapestry of the events that have transformed the feld over the last decade that is both authentic and detailed. The frst section of the book provides much of the basic science background. As described in the frst two chapters, the dramatic convergence of lines of evidence from two different laboratories frst demonstrated in 1999 that narcolepsy is a disease of loss of neurotransmission by lateral hypothalamic neurons making the peptides that have been called orexins or hypocretins. These fndings did much to clarify and unify a feld that had puzzled for decades over the fundamental nature of this puzzling disease, as refected in the chapters that review its epidemiology and neuroanatomical and imaging fndings.

Book Description
Sleep-related complaints are extremely common across the spectrum of psychiatric illness. Accurate diagnosis and management of sleep disturbances requires an understanding of the neurobiological mechanisms underlying sleep and wakefulness, the characteristics of sleep disturbance inherent to psychiatric illness and primary sleep disorders, as well as the psychopharmacologic and behavioral treatments available. Foundations of Psychiatric Sleep Medicine provides a uniquely accessible, practical, and expert summary of current clinical concepts at the sleep-psychiatry interface. Topics covered include: basic principles in sleep science, clinical sleep history taking, primary sleep disorders in psychiatric contexts, and sleep disturbance across a range of mood, anxiety, psychotic, substance use, cognitive and developmental disorders. Written by outstanding experts in the field of sleep medicine and psychiatry, this academically rigorous and clinically useful text is an essential resource for psychiatrists, psychologists and other health professionals interested in the relationship between sleep and mental illness.

Book Description
The first report that rapid eye movements occur in sleep in humans was published in 1953. The research journey from this point to the realization that sleep consists of two entirely independent states of being (eventually labeled REM sleep and non-REM sleep) was convoluted, but by 1960 the fundamental duality of sleep was well established including the description of REM sleep in cats associated with “wide awake” EEG patterns and EMG suppression. The first report linking REM sleep to a pathology occurred in 1961 and a clear association of sleep onset REM periods, cataplexy, hypnagogic hallucinations and sleep paralysis was fully established by 1966. When a naïve individual happens to observe a full-blown cataplexy attack, it is both dramatic and unnerving. Usually the observer assumes that the loss of muscle tone represents syncope or seizure. In order to educate health professionals and the general public, Christian Guilleminault and I made movies of full-blown cataplectic episodes (not an easy task). We showed these movies of cataplexy attacks to a number of professional audiences, and were eventually rewarded with the report of a similar abrupt loss of muscle tone in a dog. We were able to bring the dog to Stanford University and with this as the trigger, we were able to develop the Stanford Canine Narcolepsy Colony. Breeding studies revealed the genetic determinants of canine narcolepsy, an autosomal recessive gene we termed canarc1. Emmanuel Mignot took over the colony in 1986 and began sequencing DNA, finally isolating canarc1 in 1999.

Book Description
This volume connects current ideas and concepts about sleep functions and circadian rhythms with the search for novel target-selective sleep-wake therapeutics. To do so, it provides a timely, state-of-the-art overview of sleep-wake mechanisms in health and disease, ongoing developments in drug discovery, and their prospects for the clinical treatment of sleep-disordered patients. It particularly focuses on the concept that sleep and wakefulness mutually affect each other, and the future therapeutic interventions with either sleep- or wake-promoting agents that are expected to not only improve the quality of sleep but also the waking behavior, cognition, mood and other sleep-associated physiological functions.

Book Description
The human hypothalamus, a small structure at the base of the brain, has strategic importance for the harmonic function of the human body. It controls the autonomic nervous system, neuroendocrine function, circadian and circannual rhythms, somatic activities, and behavior, and is situated at the borders between the brain and the body and the brain and the soul, meeting points for mind and body. The hypothalamus is involved in a wide range of higher mental functions, including attention, learning and reinforcement of mnemonic processes, emotional control, mood stability, and cognitive-emotional interactions. It also has a role to play in behavioral disorders, panic reactions, cluster headache, gelastic epilepsy, mental deficiency, periodic disorders, depression, autism, and schizophrenia, and in a substantial number of neurodegenerative diseases. It enlarges greatly the dimensions of the hypothalamic contribution in controlling psychosomatic equilibrium and retaining internal unity of the human existence.

Book Description
Pharmacological approaches to our understanding of sleep have been at the forefront of sleep research for many years. Traditional techniques have included the use of pharmacological agonists and antagonists, as well as transmitter-specific lesions. These have been enhanced by the introduction of molecular genetics and the use of transgenes and targeted gene deletion. Neurochemistry of Sleep and Wakefulness is an exceptional, single source of information on the role of the major mammalian neurotransmitter systems involved in the regulation of sleep and waking. With contributions from internationally recognized experts, this book clearly describes how researchers have made use of the myriad techniques in their armamentarium to characterize the role of a given neurotransmitter in the regulation of sleep and waking. Suitable for experimental and clinical pharmacologists, the book will have wider appeal to sleep researchers, psychiatrists and any professional interested in the interdisciplinary areas of neurobiology and pharmacology.
