Handbook of Sleep Research, Volume 30, provides a comprehensive review of the current status of the neuroscience of sleep research. It begins with an overview of the neural, hormonal and genetic mechanisms of sleep and wake regulation before outlining the various proposed functions of sleep and the role it plays in plasticity, and in learning and memory. Finally, the book discusses disorders of sleep and waking, covering both lifestyle factors that cause disrupted sleep and psychiatric and neurological conditions that contribute to disorders. Emphasizes a comparative and multidisciplinary approach to the topic of sleep Covers the neurobiology and physiology of sleep stages, mechanisms of waking, and dreaming Discusses in detail the proposed functions of sleep, from health and rest, to memory consolidation and synaptic plasticity Examines the current state of research in mammalian and non-mammalian species, ranging from primates to invertebrates

Right after "Is it a boy or a girl?" and "What's his/her name?," the next question people invariably ask new parents is "Are you getting any sleep?" Unfortunately, the answer is usually "Not much." In fact, studies show that approximately 25% of young children experience some type of sleep problem and, as any bleary-eyed parent will attest, it is one of the most difficult challenges of parenting. Drawing on her ten years of experience in the assessment and treatment of common sleep problems in children, Dr. Jodi A. Mindell now provides tips and techniques, the answers to commonly asked questions, and case studies and quotes from parents who have successfully solved their children's sleep problems. Unlike other books on the subject, Dr. Mindell also offers practical tips on bedtime, rather than middle-of-the-night-sleep training, and shows how all members of the family can cope with the stresses associated with teaching a child to sleep.

Sleep and wakefulness undergo important changes with age. Awakening, a crucial event in the sleep-wake rhythm, is a transition implying complex physiological mechanisms. Its involvement in sleep disturbances is also well known. This collective volume is the first attempt to systematically approach awakening across development.A methodological section considers criteria to define awakening in a developmental perspective. Theoretical considerations on development of wakefulness and on its relation to consciousness are included and provide a vigorous impulse to go beyond present criteria and classifications. Age changes are the core of studies on development: a section of the book examines old and new data from preterm to infants up to children, underscoring the main turning points along this developmental path. As for other aspects of development, awakening and the sleep-wake cycle are also influenced by external factors, both physical and human. Several contributions deal with this topic, in particular focusing on the parent-infant interaction and the influences of culture. Clinical contexts offer an opportunity to show both quantitative and qualitative changes of awakening and arousals in different pathological conditions. Either partial changes of one physiological variable or global and massive changes can be observed. (Series B)

This practical and easily navigable book covers the gamut of issues that need to be understood to provide excellent medical care for those with ADHD. Outside of mental health professionals, those who most often treat ADHD are primary care providers such as family practitioners, pediatricians, nurse practitioners, physician assistants, and school personnel. Based on clinical conversations with patients with ADHD and their families, this book provides concise, useful, up to date information of a practical nature for most, if not all of the problems, associated conditions and questions that arise when an individual has concerns about ADHD. Treatments discussed include a thorough review of medication options, with expected results and side effects, as well as other recommended treatments including a variety of therapeutic modalities, and a review of less commonly considered but important interventions regarding general health, sleep, diet, exercise, and school interventions. Readers will gain an understanding of what ADHD is, practical reviews of the literature that will help in discussion with patients and their families the importance of intervention, and all the resources and options available to provide the best treatment strategies for anyone who has ADHD as well as the commonly associated conditions.

Over the past three years I have grown accustomed to the puzzled look which appears on people's faces when they hear that I am a mathematician who studies sleep. They wonder, but are usually too polite to ask, what does mathematics have to do with sleep? Instead they ask the questions that fascinate us all: Why do we have to sleep? How much sleep do we really need? Why do we dream? These questions usually spark a lively discussion leading to the exchange of anecdotes, last night's dreams, and other personal information. But they are questions about the func tion of sleep and, interesting as they are, I shall have little more to say about them here. The questions that have concerned me deal instead with the timing of sleep. For those of us on a regular schedule, questions of timing may seem vacuous. We go to bed at night and get up in the morning, going through a cycle of sleeping and waking every 24 hours. Yet to a large extent, the cycle is imposed by the world around us.

If are you looking to expand your knowledge to the outermost limits of the universe and beyond, even if you are afraid it will be too difficult to understand, then this is the definitely right place for you. Quantum physics is an integral part of our lives, and it is extremely important for us to have at least a basic knowledge of the subject. Most people struggle with it, as there are scarcely any books on the topic that are compatible with the needs and demands of people who are just starting out as physicists and need a simple guide to understand the concepts. Here’s some of the information included in the book: Quantization and the uncertainty prinicple Relation between waves and particles Quantum physics - the fascination Quantum physics - the battle The axioms of quantum physics and Planck's constant The law of attractions You don’t need to be a genius or an academic to uncover the secrets of quantum mechanics, you just need a curious and open mind. The enneagram is a personality type that can bring to you a lot of benefits! There are a lot of things that help us to distinguish one from another, and all of them can be explained by a unique analysis system called Enneagram. This system was made to determine a specific personality type and to predict behaviors. Its accuracy made people ask themselves if there was a spiritual element in the system. Enneagram is a tool designed to help simplify and increase people's knowledge of themselves. Here is a professional guide about how Enneagram works and a collection of tests that will help you discover yourself. Here is what you will find inside the Enneagram book: How the Enneagram works and how to find out which is your basic personality type How to use the Enneagram as a tool to benefit your life What is the awakening soul A test to find out what your personality type is What is the Enneagram and how to use it Types of Enneagram personalities The Enneagram is a universal symbol of an ancient teaching An Enneagram is a wonderful tool, but a tool is only as good as the purposes it’s used for. As you discern the types of other people in your life, you can use the Enneagram to navigate interactions, being mindful of your own biases and tailoring communication to their goals and perspectives. You can introduce the system to groups, creating a common language for members to understand each other. Simply put, this book will answer the big question. Why do you do what you do, whether or not it's voluntary?
