Book Description
This book provides an update for the rapidly developing technology known as “optogenetics”, which is the use of genetically encoded light-sensitive molecular elements (usually derived from lower organisms) to control or report various physiological and biochemical processes within the cell. Two ongoing clinical trials use optogenetic tools for vision restoration, and optogenetic strategies have been suggested as novel therapies for several neurological, psychiatric and cardiac disorders. This Special Issue comprises two reviews and seven experimental papers on different types of light-sensitive modules widely used in optogenetic studies. These papers demonstrate the efficiency and versatility of optogenetics and are expected to be equally relevant for advanced users and beginners considering using optogenetic tools in their research.

Book Description
This book, now in a thoroughly revised second edition, offers a comprehensive review of the rapidly growing field of optogenetics, in which light-sensing proteins are genetically engineered into cells in order to acquire information on cellular physiology in optical form or to enable control of specific network in the brain upon activation by light. Light-sensing proteins of various living organisms are now available to be exogenously expressed in neurons and other target cells both in vivo and in vitro. Cellular functions can thus be manipulated or probed by light. The new edition documents fully the extensive progress since publication of the first edition to provide an up-to-date overview of the physical, chemical, and biological properties of light-sensing proteins and their application in biological systems, particularly in neuroscience but also in medicine and the optical sciences. Underlying principles are explained and detailed information provided on a wide range of optogenetic tools for the observation and control of cellular signaling and physiology, gene targeting technologies, and optical methods for biological applications. In presenting the current status of optogenetics and emerging directions, this milestone publication will be a “must read” for all involved in research in any way related to optogenetics.

Book Description
Optogenetics represents a breakthrough technology capable of dynamically modulating molecular and cellular activity in live cells with high precision. This transformative technology made it possible to reversibly interrogate protein actions, cellular events, and animal behaviors with a simple flash of light. Manipulating the temporal and spatial profile of light enabled precise control of membrane potentials. This feature has inspired non-opsin-based optogenetics, which not only inherits the precise spatiotemporal resolution but also expands the targets into a diverse pool of biomolecules such as membrane receptors, ion channels, kinases, GTPases, and transcription factors. This book is unique because it emphasizes the design and applications of opsin-free optogenetic tools. Key Features Describes new developments in non-opsin-based optogenetic tools Introduces cutting-edge methods for precise modulation of cell signaling Highlights applications of optogenetic regulation of cellular functions Covers contributions from an international team of leading experts Related Titles Lim, W. & B.

Book Description
"Neuroscience research has been illuminated by the application of light-sensitive proteins, called opsins, in manipulating neuronal function. Optogenetics has been readily applied in mice, however the application of this techniques in non-human primates (NHPs) has produced underwhelming results. These challenges can largely be attributed to the immense size difference between rodent and primate brains. Additional challenges such as adaptive immunity and increased brain complexity may also contribute. We have identified and addressed several challenges that have hindered successful optogenetic manipulations in NHPs including difficulties in selecting an appropriate vector, unreliable viral vector batch quality and efficacy, inefficient injection protocols, tissue damage and light-derived artifacts from poor optrode design, and poor light propagation through brain tissue. This study sough to address these issues through in vivo and in vitro investigations to yield a streamlined methodology for achieving NHP optogenetics. To determine an optimal vector for NHP transgene delivery, we compared the transduction efficiency of a panel of 14 different serotypes of the adeno-associated virus (AAV) on neurons differentiated from Macaca fascicularis embryonic stem cells. AAV6 was ultimately found to produce the highest transduction efficiency, followed by AAV2. We then developed a cohesive methodology for in vivo NHP optogenetics manipulation, including an in-chair viral injection strategy, utilizing opsins possessing red-shifted activation spectrum, and fabricating tapered optical fibers paired with thin electrodes to reduce tissue damage upon insertion. This methodology was then applied in vivo, successfully achieving electrophysiological optogenetic manipulation in the primate lateral geniculate nucleus and electrophysiological and behavioural manipulation in the horizontal and vertical oculomotor centres of the brain stem"--

Book Description
Edited and authored by a wealth of international experts in neuroscience and related disciplines, this key new resource aims to offer medical students and graduate researchers around the world a comprehensive introduction and overview of modern neuroscience. Neuroscience research is certain to prove a vital element in combating mental illness in its various incarnations, a strategic battleground in the future of medicine, as the prevalence of mental disorders is becoming better understood each year. Hundreds of millions of people worldwide are affected by mental, behavioral, neurological and substance use disorders. The World Health Organization estimated in 2002 that 154 million people globally suffer from depression and 25 million people from schizophrenia; 91 million people are affected by alcohol use disorders and 15 million by drug use disorders. A more recent WHO report shows that 50 million people suffer from epilepsy and 24 million from Alzheimer’s and other dementias. Because neuroscience takes the etiology of disease—the complex interplay between biological, psychological, and sociocultural factors—as its object of inquiry, it is increasingly valuable in understanding an array of medical conditions. A recent report by the United States’ Surgeon General cites several such diseases: schizophrenia, bipolar disorder, early-onset depression, autism, attention deficit/ hyperactivity disorder, anorexia nervosa, and panic disorder, among many others. Not only is this volume a boon to those wishing to understand the future of neuroscience, it also aims to encourage the initiation of neuroscience programs in developing countries, featuring as it does an appendix full of advice on how to develop such programs. With broad coverage of both basic science and clinical issues, comprising around 150 chapters from a diversity of international authors and including complementary video components, Neuroscience in the 21st Century in its second edition serves as a comprehensive resource to students and researchers alike.

Book Description
The subject of optogenetics is comprehensively covered in this book, including physical, chemical, and biological topics of light-sensing proteins and their application in biological systems, particularly in neuroscience and medicine and the related opto-electronics. Optogenetics is a new technology that combines genetics and optics. It enables one to manipulate or measure the function of identified cells or neurons in a tissue by light with an accuracy in the range of milliseconds, even in a freely moving animal. Optogenetics has already become a powerful tool for revealing the neural mechanisms underlying behavior and analyzing various physiological phenomena. It is also expected to become useful for treating neural dysfunctions such as Parkinson disease and for the development of a brain-machine interface. This book should be read by any scientist or student performing research in any way related to optogenetics. As a milestone publication on optogenetics, this book will serve as a compass for any researcher, from beginners to experts, to explore this uncharted world.
