The Atlas of Early Zebrafish Brain Development is the first neuroanatomical expression atlas of important genetic and immunohistochemical markers of a vertebrate model system. In-situ hybridized and immunostained preparations of complete series of brain sections reveal markers of the fundamental stages in the life history of neuronal cells (proliferation/determination, migration and neuronal differentiation) in very high quality preparations and photographic plates. Early brain organization is vividly demonstrated and local variations in brain development are shown in a holistic view. This book represents a key reference and interpretation matrix to analyze expression domains of genes involved in Zebrafish brain development and neurogenesis and thus represents a milestone in this research area. There is simply no alternative source for combined neuroanatomical and gene expression data in the Zebrafish at this level of detail. The book introduces the reader to the field and shows principles of vertebrate brain development and neurogenesis. It will also be of great value to investigators of other model organisms such as frog, chick and mouse.

Zebrafish are widely considered an excellent model system for vertebrate development. The embryo is transparent, thereby enabling visualization and use of labelling and transgenic approaches. Moreover, because of the ease of inducing new mutations in zebrafish and similarity with the human genome, this organism may be used effectively for disease studies. For example, mutant zebrafish are being utilized for testing drugs that will combat a range of human diseases, from Alzheimer's and cancer to kidney failure and congenital heart disease. For the first time, this atlas provides the research community with a complete reference for zebrafish anatomy spanning the early embryo all the way to adulthood. The authors employ the technique of optical projection tomography (OPT), and offer a series of sections in multiple planes from each sample. The contents are organized by developmental stages, with over 200 images that contain annotations describing anatomical structures relevant to development. In addition, chapters feature explanatory text that highlights major developments in the zebrafish during each stage. * Provides the first comprehensive anatomical resource that covers all regions of zebrafish anatomy from the larval period to adulthood. * The over 200 images include explanatory notes * Each chapter contains a concise description of key anatomical features that factor in zebrafish development * Despite many years of use as a model system, until now there has never been a guide to zebrafish at the larval stage. * The book's website contains a database of over 10k sections from different regions as well as 3D images that are interactive.

Theneurotransmitter dopamine has just celebrated its 50thbirthday. The discovery of dopamine as a neuronal entity in the late 1950s and the notion that it serves in neurotransmission has been a milestone in the field of neuroscience research. This milestone marked the beginning of an era that explored the brain as an integrated collection of neuronal systems that one could distinguish on basis of neurotransm- ter identities, and importantly, in which one started to be able to pinpoint the seat of brain disease. The mesodiencephalic dopaminergic (mdDA) system, previously designated as midbraindopaminergic system, has received much attention since its discovery. The initial identification of dopamine as a neurotransmitter in the central nervous system (CNS) and its relevance to psychiatric and neurological disorders have stimulated a plethora of neurochemical, pharmacological and genetic studies into the function of dopamine neurons and theirprojections. In the last decade, studies on gene expression and development have further increased the knowledge of this neuronal population and have unmasked a new level of complexity. The start of the molecular dissection of the mdDA system has been marked by the cloning and characterization ofNurrl and Pitx3. These transcription factors were shown to have a critical function during mdDA development. These initial studies have been followed by the identification of many other proteins, which have a crucial function in the creation of a dopamine neuron permissive region, induction of precursors, induction of terminaldifferent- tion and finally maintenance of the mdDA neuronal pool.

Adult neurogenesis occurs in proliferative zones of the brain that contain neural progenitor cell populations capable of differentiating into specific cell types. However, we remain limited in our understanding of the signals that regulate neural progenitor cell proliferation and differentiation in adults. Recently zebrafish (Danio rerio) have emerged as an excellent model for studying the molecular mechanisms behind adult neurogenesis, because sixteen proliferative zones remain active in the adult brains. Thousands of fluorescent transgenic reporter lines have been generated in zebrafish that reveal gene expression patterns of cell-cell signaling systems, some of which may regulate neurogenesis in these brain regions. Using a new tissue clearing technique and whole brain imaging with fluorescent light sheet microscopy (FLSM) we have generated the first 3-Dimensional atlas of gene expression in an intact adult zebrafish brain. So far we have created a reference brain image and have aligned the expression patterns from three transgenic lines. This work is a preliminary step in the generation of a new, open access brain atlas called the Zebrafish Adult Brain Browser (ZABB). While generating this atlas we focused on documenting the adult brain regions responsive to Sonic Hedgehog (Shh), a cell-cell signaling system known to regulate neurogenesis during embryonic development. We used two Shh-reporter lines to create another atlas comparing reporter transgene expression in whole brain and sectioned tissue to the expression of the Hedgehog (Hh) target gene ptch2 using in situ hybridization. We show that the reporter lines reveal different Hh responsive domains, but together identify fourteen Hh responsive regions in the brain, nine of which are known proliferative zones. Thus, it appears that subsets of both proliferating neural progenitors and non-proliferative cells remain Hh responsive in adult brains. Our data suggests that Hh signaling contributes to the regulation of neural progenitor cells in nine of the sixteen proliferative zones. Uncovering the molecular mechanisms behind adult neurogenesis and forming a greater understanding of adult neural stem cell regulation has the potential to influence the treatment of many neurodegenerative diseases and cancers.

Understanding how the brain functions is one of the most ambitious current scientific goals. This challenge will only be accomplish by a multidisciplinary approach involving genetics, molecular biology, optics, ethology, neurobiology and mathematics and using tractable model systems. The zebrafish larva is a transparent genetically tractable small vertebrate, ideal for the combination state-of-the- art imaging techniques (e.g. two-photon scanning microscopy, single-plane illumination microscopy, spatial light modulator microscopy and lightfield microscopy), bioluminiscence and optogenetics to monitor and manipulate neuronal activity from single specific neurons up to the entire brain, in an intact behaving organism. Furthermore, the zebrafish model offers large and increasing collection of mutant and transgenic lines modelling human brain diseases. With these advantages in hand, the zebrafish larva became in the recent years, a novel animal model to study neuronal circuits and behaviour, taking us closer than ever before to understand how the brain controls behaviour.

Evolution of Nervous Systems, Second Edition is a unique, major reference which offers the gold standard for those interested both in evolution and nervous systems. All biology only makes sense when seen in the light of evolution, and this is especially true for the nervous system. All animals have nervous systems that mediate their behaviors, many of them species specific, yet these nervous systems all evolved from the simple nervous system of a common ancestor. To understand these nervous systems, we need to know how they vary and how this variation emerged in evolution. In the first edition of this important reference work, over 100 distinguished neuroscientists assembled the current state-of-the-art knowledge on how nervous systems have evolved throughout the animal kingdom. This second edition remains rich in detail and broad in scope, outlining the changes in brain and nervous system organization that occurred from the first invertebrates and vertebrates, to present day fishes, reptiles, birds, mammals, and especially primates, including humans. The book also includes wholly new content, fully updating the chapters in the previous edition and offering brand new content on current developments in the field. Each of the volumes has been carefully restructured to offer expanded coverage of non-mammalian taxa, mammals, primates, and the human nervous system. The basic principles of brain evolution are discussed, as are mechanisms of change. The reader can select from chapters on highly specific topics or those that provide an overview of current thinking and approaches, making this an indispensable work for students and researchers alike. Presents a broad range of topics, ranging from genetic control of development in invertebrates, to human cognition, offering a one-stop resource for the evolution of nervous systems throughout the animal kingdom Incorporates the expertise of over 100 outstanding investigators who provide their conclusions in the context of the latest experimental results Presents areas of disagreement and consensus views that provide a holistic view of the subjects under discussion

In this book, leading scientists in the fields of sensory biology, neuroscience, physics and engineering explore the basic operational principles and behavioral uses of flow sensing in animals and how they might be applied to engineering applications such as autonomous control of underwater or aerial vehicles. Although humans possess no flow-sensing abilities, countless aquatic (e.g. fish, cephalopods and seals), terrestrial (e.g. crickets and spiders) and aerial (e.g. bats) animals have flow sensing abilities that underlie remarkable behavioral feats. These include the ability to follow silent hydrodynamic trails long after the trailblazer has left the scene, to form hydrodynamic images of their environment in total darkness, and to swim or fly efficiently and effortlessly in the face of destabilizing currents and winds.

The brain of each animal shows specific traits that reflect its phylogenetic history and its particular lifestyle. Therefore, comparing brains is not just a mere intellectual exercise, but it helps understanding how the brain allows adaptive behavioural strategies to face an ever-changing world and how this complex organ has evolved during phylogeny, giving rise to complex mental processes in humans and other animals. These questions attracted scientists since the times of Santiago Ramon y Cajal one of the founders of comparative neurobiology. In the last decade, this discipline has undergone a true revolution due to the analysis of expression patterns of morphogenetic genes in embryos of different animals. The papers of this e-book are good examples of modern comparative neurobiology, which mainly focuses on the following four Grand Questions: a) How are different brains built during ontogeny? b) What is the anatomical organization of mature brains and how can they be compared? c) How do brains work to accomplish their function of ensuring survival and, ultimately, reproductive success? d) How have brains evolved during phylogeny? The title of this e-book, Adaptive Function and Brain Evolution, stresses the importance of comparative studies to understand brain function and, the reverse, of considering brain function to properly understand brain evolution. These issues should be taken into account when using animals in the research of mental function and dysfunction, and are fundamental to understand the origins of the human mind.
