Neuronal Oscillations Of Wakefulness And Sleep

The purpose of this work is to review recent findings highlighting the mechanisms and functions of the neuronal oscillations that structure brain activity across the sleep-wake cycle. An increasing number of studies conducted in humans and animals, and using a variety of techniques ranging from intracellular recording to functional neuroimaging, has provided important insight into the mechanisms and functional properties of these brain rhythms. Studies of these rhythms are fundamental not only for basic neuroscience, but also for clinical neuroscience. At the basic science level, neuronal oscillations shape the interactions between different areas of the brain and profoundly impact neural responses to the environment, thereby mediating the processing of information in the brain. At the clinical level, brain oscillations are affected in numerous neurological conditions and might provide useful biomarkers that inform about patients’ evolution and vulnerability. During sleep, these brain rhythms could provide functional support to internal states that govern the basic maintenance of local circuit and systemic interactions. During wake, the rhythmicity of cortical and subcortical circuits have been linked with sensory processing, cognitive operations, and preparation for action. This book will attempt to link together these sleep and wake functional roles at the level of neuroimaging and electroencephalographic measures, local field potentials, and even at the cellular level. ​

This book is part of an ongoing history of efforts to understand the nature of waking and sleeping states from a biological point of view. We believe the recent technological revolutions in anatomy and physiology make the present moment especially propitious for this effort. In planning this book we had the choices of producing an edited volume with invited chapter authors or of writing the book ourselves. Edited volumes offer the opportunity for expression of expertise in each chapter but, we felt, would not allow the development of our ideas on the potential and actual unity of the field and would not allow the expression of coherence that can be obtained only with one or two voices, but which may be quite difficult with a chorus assembled and performing together for the first time. (Unlike musical works, there is very little precedent for rehearsals and repeated performances for authors of edited volumes or even for the existence of conductors able to induce a single rhythm and vision of the composition. ) We thus decided on a monograph. The primary goal was to communicate the current realities and the future possibilities of unifying basic studies on anatomy and cellular physiology with investigations of the behavioral and physi ological events of waking and sleep. In keeping with this goal we cross-reference the basic cellular physiology in the latter chapters, and, in the last chapter, we take up possible links to relevant clinical phenomenology.

This volume of Progress in Brain Research documents research presented at the 26th International Summer School of Brain Research (Amsterdam, Jun/Jul 2010) and looks at how the oscillations that characterize brain activity vary between task performance - the EEG power and performance modulations, rest - the MRI default mode and other networks, and sleep - the cortical slow oscillations. Studies over the past decade indicate that the study of these slow oscillations is essential for our understanding of plasticity, memory, brain structure from synapse to default mode network, cognition, consciousness and ultimately for our understanding of the mechanisms and functions of sleep and vigilance. Leading authors review the state-of-the-art in their field of investigation and provide their views and perspectives for future research Chapters are extensively referenced to provide readers with a comprehensive list of resources on the topics covered All chapters include comprehensive background information and are written in a clear form that is also accessible to the non-specialist

Jasper's Basic Mechanisms, Fourth Edition, is the newest most ambitious and now clinically relevant publishing project to build on the four-decade legacy of the Jasper's series. In keeping with the original goal of searching for "a better understanding of the epilepsies and rational methods of prevention and treatment.", the book represents an encyclopedic compendium neurobiological mechanisms of seizures, epileptogenesis, epilepsy genetics and comordid conditions. Of practical importance to the clinician, and new to this edition are disease mechanisms of genetic epilepsies and therapeutic approaches, ranging from novel antiepileptic drug targets to cell and gene therapies.

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.

An up-to-date, superbly illustrated practical guide to the effective use of neuroimaging in the patient with sleep disorders. The only book to date to provide comprehensive coverage of this topic. A must for all healthcare workers interested in understanding the causes, consequences and treatment of sleep disorders.
