Neuroanatomy for the XXIst Century


Book Description

An explosion of new techniques with vastly improved visualization and sensitivity is leading a veritable revolution in modern neuroanatomy. Basic questions related to cell types, input localization, and connectivity are being re-visited and tackled with significantly more accurate and higher resolution experimental approaches. A major goal of this e-Book is thus to highlight in one place the impressive range of available techniques, even as these are fast becoming routine. This is not meant as a technical review, however, but rather will project the technical explosion as indicative of a field now in a vibrant state of renewal. Thus, contributions will be mainly research articles using the newer techniques. A second goal is to showcase what has become the conspicuous interdisciplinary reach of the field: neuroanatomical standards and the close association of structure-function and underlying circuitry mechanisms are increasingly relevant to investigations in development, physiology, and disease. Another feature of this Research Topic is that it includes a breadth of cross-species contributions from investigators working with rodent, nonhuman primate, and human brains. This is important since most of our current knowledge of brain structure has been obtained from experimental animals. However, recent technical advances, coupled with researcher willingness to use the human tissue available, will undoubtedly lead to major advances in the near future regarding human brain mapping and connectomes. Thus, of particular interest will be the methods that can help to define general wiring principles in the brain, both structural and functional. Overall, the state of the field is: exciting.




Experimental Neuroanatomy


Book Description

A practical guide to the most important and up-to-date techniques used in experimental neuroanatomy. It should be of use to anyone wishing to apply these important techniques, especially neuroscientists and neuroanatomists.




Statistical and Computational Methods in Brain Image Analysis


Book Description

The massive amount of nonstandard high-dimensional brain imaging data being generated is often difficult to analyze using current techniques. This challenge in brain image analysis requires new computational approaches and solutions. But none of the research papers or books in the field describe the quantitative techniques with detailed illustrations of actual imaging data and computer codes. Using MATLAB® and case study data sets, Statistical and Computational Methods in Brain Image Analysis is the first book to explicitly explain how to perform statistical analysis on brain imaging data. The book focuses on methodological issues in analyzing structural brain imaging modalities such as MRI and DTI. Real imaging applications and examples elucidate the concepts and methods. In addition, most of the brain imaging data sets and MATLAB codes are available on the author’s website. By supplying the data and codes, this book enables researchers to start their statistical analyses immediately. Also suitable for graduate students, it provides an understanding of the various statistical and computational methodologies used in the field as well as important and technically challenging topics.




The Neurobiological Basis of Suicide


Book Description

With recent studies using genetic, epigenetic, and other molecular and neurochemical approaches, a new era has begun in understanding pathophysiology of suicide. Emerging evidence suggests that neurobiological factors are not only critical in providing potential risk factors but also provide a promising approach to develop more effective treatment and prevention strategies. The Neurobiological Basis of Suicide discusses the most recent findings in suicide neurobiology. Psychological, psychosocial, and cultural factors are important in determining the risk factors for suicide; however, they offer weak prediction and can be of little clinical use. Interestingly, cognitive characteristics are different among depressed suicidal and depressed nonsuicidal subjects, and could be involved in the development of suicidal behavior. The characterization of the neurobiological basis of suicide is in delineating the risk factors associated with suicide. The Neurobiological Basis of Suicide focuses on how and why these neurobiological factors are crucial in the pathogenic mechanisms of suicidal behavior and how these findings can be transformed into potential therapeutic applications.




Neuroanatomy: Draw It to Know It


Book Description

"If you can't draw it, you don't know it:" that was the rule of the late neuroanatomist William DeMyer, MD. Yet books do not encourage us to draw and redraw neuroanatomy. Neuroanatomy: Draw It to Know It teaches neuroanatomy through step-by-step instruction of how to draw neuroanatomical pathways and structures. Its instructive language is highly engaging. Users draw neuroanatomical structures and pathways in several steps so they are remembered and use mental and physical mnemonics to demonstrate difficult anatomical rotations and directional pathways. Anatomical pictures and radiographic images accompany the diagrams to clarify spatially challenging features; relevant synonyms are listed to avoid inter-text confusion; inconsistencies in the neuroanatomy literature are highlighted to mitigate frustration; and historical and current accounts of neuroanatomical systems are presented for perspective. Many neuroanatomy textbooks are great references, but fail to provide a working knowledge of neuroanatomy, and many neuroanatomy handbooks provide bedside pearls, but are too concise to be fully satisfactory. This instructional workbook teaches a comprehensive, but practical approach to neuroanatomy; it includes references where necessary but steers users toward key clinical features. Most importantly, Neuroanatomy: Draw It to Know It instructs the reader to draw and redraw the anatomy and teaches an active approach to learning.




Neuroanatomical Tract-Tracing


Book Description

The first two editions of this title had a tremendous impact in neuroscience. Between the Second edition in 1989 and today, there has been an explosion of information in the field, including advances in molecular techniques, such as genomics and proteomics, which have become increasing important in neuroscience. A renaissance in fluorescence has occurred, driven by the development of new probes, new microscopes, live imagers, and computer processing. The introduction of new markers has enormously stimulated the field, moving it from tissue culture to neurophysiology to functional MRI techniques.




Human Brain Anatomy in Computerized Images


Book Description

By using non-invasive tomographic scans, modern neuroimaging technologies are revealing the structure of the human brain in unprecedented detail. This spectacular progress, however, poses a critical problem for neuroscientists and for practitioners of brain-related professions: how to find their way in the current tomographic images so as to identify a particular brain site, be it normal or damaged by disease? Prepared by a leading expert in advanced brain-imaging techniques, this unique atlas is a guide to the localization of brain structures that illustrates the wide range of neuroanatomical variation. It is based on the analysis of 29 normal human brains obtained from three-dimensional reconstructions of magnetic resonance scans of living persons. The Second Edition of this atlas offers entirely new images, all from new brain specimens.
