Book Description
It is unclear whether the properties of neuronal circuits beyond the retina limit the spatial and temporal resolution of vision. The kinetics of neurotransmission at central synapses should limit an animal's ability to see rapid movements. Accurate retinotopy should be essential for the perception of fine spatial detail. We have tested these predictions using the zebrafish blumenkohl (blu) mutant. Positional cloning revealed that the blu gene encodes vglut2a, a vesicular glutamate transporter expressed by retinal ganglion cells. blu mutants' retinotectal synapses show diminished responses to high frequency electrical stimulation, which should reduce the visibility of fast-moving visual stimuli. Single retinal axons in blu mutants arborize over a larger area in the tectum, blurring the fine detail of the retinotopic map, which should compromise spatial acuity. We tested these hypotheses using assays for optomotor responses and prey capture. Our study provides experimental support for previously untested principles of sensory coding.

Book Description
A central goal of neuroscience is to understand the neural basis of behavior. The zebrafish is a vertebrate model system that allows behavior to be studied using both systems and molecular genetic approaches. Here we present a psychophysical and genetic analysis of optomotor behavior in zebrafish larvae. By applying psychophysical methods developed for primates to zebrafish we have demonstrated than motion detection in zebrafish uses mechanisms that are broadly similar to humans. The larvae are susceptible to visual illusions that indicate that they detect Fourier motion energy in visual scenes. They also respond to non-Fourier motion, an ability that is believed to depend on visual cortex in humans. Different visual behaviors in the fish use different chromatic information. The optomotor response, in particular, is colorblind and pools signals from longer wavelength cones, while excluding shorter wavelength inputs. Motion processing seems to be functionally similar between higher and lower vertebrates despite large differences in neuroanatomy. Using an automated assay, we have conducted a large-scale genetic screen for recessive mutants affecting the optomotor response. Testing these mutants with a battery of behavioral assays allows us to categorize them into motor and visual system mutants, as well as some that are specific to the optomotor response. Many have normal visual system anatomy, but some are missing specific cell-types or have defects in axon target selection.

Book Description
Behavioral and Neural Genetics of Zebrafish assembles the state-of-the-art methodologies and current concepts pertinent to their neurobehavioral genetics. Discussing their natural behavior, motor function, learning and memory, this book focuses on the fry and adult zebrafish, featuring a comprehensive account of modern genetic and neural methods adapted to, or specifically developed for, Danio rerio. Numerous examples of how these behavioral methods may be utilized for disease models using the zebrafish are presented, as is a section on bioinformatics and "big-data" related questions. Provides the most comprehensive snapshot of the fast-evolving zebrafish neurobehavior genetics field Describes behavioral, genetic and neural methods and concepts for use in adult and larval zebrafish Features examples of zebrafish models of human central nervous system disorders Discusses bioinformatics questions pertinent to zebrafish neurobehavioral genetics

Book Description
Animal models and tests have become increasingly important for biomedical research, enabling a better understanding of pathogenic pathways involved in various human disorders. Over the last decades, zebrafish (Danio rerio) have become a very popular model organism in biomedical research. Recently, this fish has entered the waters of neuroscience and biological psychiatry, quickly becoming an indispensable model species in this field. With a high genetic homology to humans (~75% based on coding regions), it is not surprising that humans and fish are very similar physiologically (and behaviorally). Therefore, it should not come as a surprise that zebrafish can be an excellent model of human neuropsychiatric disorders. While some classical psychiatrists may not too easily be persuaded by this generalization, the current book “The rights and wrongs of zebrafish: principles of behavioral phenotyping and CNS disease modeling” explains, in a domain-by-domain manner, how exactly zebrafish models can be used to target a wide range of human brain disorders and aberrant phenotypes. The contributors to this book are leading international scholars whose work spearheads innovative zebrafish neuroscience research around the world. Written by top experts in the field, this book makes for a useful, balanced and up-to-date reading that outlines the use of zebrafish to study the pathological mechanisms underlying neuropsychiatric disorders.

Book Description
Animal models have traditionally played a crucial role in improving our understanding of brain pathogenesis. Zebrafish (Danio rerio) have generated considerable discoveries in the areas of genetics, embryology, endocrinology, and neuroscience. Zebrafish Models in Neurobehavioral Research emphasizes the growing importance of zebrafish in neurobehavioral research and portrays an extensive, thorough perspective on the emergence of zebrafish as robust and translational models. Written by leading international experts, the book covers major topics ranging from stress to learned recognition of environment, encompassing a wide spectrum of the utility of zebrafish within neurobiological disciplines. The chapters provide authoritative reviews of many zebrafish paradigms commonly used in the field today. This book will be a useful guide for zebrafish researchers, and will complement another related book from the popular Neuromethods series, Zebrafish Neurobehavioral Protocols. Comprehensive and up-to-date, Zebrafish Models in Neurobehavioral Research serves as an ideal resource for scientists new to the field as well as for established researchers seeking valuable insight into the growing utility of zebrafish in neuroscience.

Book Description
Zebrafish (Danio rerio) play an integral role in biomedical research, enabling researchers to examine physiological mechanisms and pathways relevant to human pathogenesis and its therapy. That, along with their low cost, easy manipulation, short reproductive cycles, and physiological homology to humans, has made zebrafish a vital model organism for neuroscience research. Zebrafish Protocols for Neurobehavioral Research addresses protocols for both larval and adult models, written by the leading experts in the field of zebrafish research. Part I of this book takes advantage of the high-throughput nature of larval models to offer protocols for research requiring high output, easily manipulated screens. The second half of the book focuses on the robust and sophisticated behaviors of adult zebrafish, suitable for the neurophenotyping of complex traits and multi-domain disorders. Importantly, these models complement each other, working together to provide researchers with valuable insights into neurobiology of normal and pathological behavior. Thorough and cutting-edge, this volume is a useful, authoritative reference guide that should hold a coveted spot in zebrafish laboratories across the globe.
