This book was released on 2013 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objectives: Current analyses of 3D cone beam computed tomography (CBCT) images used in orthodontic diagnosis and treatment planning still rely upon 2D linear and angular measures, along with subjective visual evaluation, to assess complex facial disharmony and other dentofacial characteristics. The overall objective of this investigation is to overcome these limitations by developing and testing protocol for mapping the surface of the human skull in three dimensions using CBCT images. In collaboration with the Laboratory of Neuroimaging (LONI) at UCLA, the specific goals of this project are: To apply and modify advanced technology used in brain mapping research to accurately and efficiently map the skull surface in 3D To apply and modify existing mathematical functions to find the average of multiple skull surfaces And to develop protocol for superimposing a sample skull on the average skull model, yielding a color-coded map of surface deviation and dysmorphology Methods: Active patient files in the UCLA Section of Orthodontics were reviewed for the presence of a NewTom ® 3G CBCT scan. The search resulted in 67 patient scans that met the inclusion criteria for the study. CBCT files in DICOM format were first uploaded into a Beta version of Dolphin Imaging ® 11.5 Software. The surface was then segmented using a triangular mesh approach, after which the file was exported to MeshLab ® for viewing and to remove undesired nodes. Topology of each skull was corrected using a principal axis star map and smoothing of the extrapolated regions. Shapes were mapped to a sphere using conformal and area preserving maps, and were then registered using a spherical patch mapping approach. Finally an average was created using 7-parameter procrustes alignment. Results: Size-standardized and non-size standardized average skull models were successfully created for the 67 patient sample. Color-coded displacement maps were generated for a sample patient to demonstrate the potential clinical applicability of this protocol. Conclusions: The results of this investigation suggest that it is possible to average multiple shapes of highly variable topology such as the human skull. The most immediate application of this research will be rapid and detailed diagnostic imaging analysis for orthodontic and surgical treatment planning, particularly in complex cases involving congenital facial anomalies, facial asymmetry, and trauma. There is also great potential for application to areas outside orthodontics such as anthropometrics and genomics.

Book excerpt: This volume represents an ongoing series entitled Biological Shape Analysis, of which this is the 4th Edition. These proceedings represent state-of-the-art research in the field of biology, broadly-based, that deal with the quantitative analysis of the shape of the biological form. These numerical analyses include Fourier analytic methods, wavelets, neural networks, machine vision, machine learning, median axis transforms, spectral clustering, genome-wide association studies, 3D surface mapping, as well as more traditional morphometric approaches. Studies included are drawn from research in agricultural genetics, anatomy, anthropology, botany, dentistry, entomology, forensics, human evolution, paleontology, primatology, to name a few.The shape of forms can be considered of central importance in terms of identification, comparison, and classification of biological organisms. These proceedings, of which this is the fourth one, are unique in that they deal extensively with a wide range of organisms in biology, including both fauna and flora. They bring together diverse practitioners from a wide variety of disciplines. This represents a major departure from the current emphasis on specialization in the biological sciences. It is of particular importance to note that these issues dealing with shape analysis of biological structures are found to be common across very diverse disciplines and these proceedings are the first ones to highlight this.There are no volumes currently available that are as broadly-based as these proceedings in dealing with the quantification of shape analysis. (1) These volumes are unique in their diversity in covering the biological disciplines; (2) The emphasis on numerical approaches; and (3) the numerous state-of-the-art research papers.
Download or read book Statistical Parametric Mapping The Analysis of Functional Brain Images written by William D. Penny and published by Elsevier. This book was released on 2011-04-28 with total page 689 pages. Available in PDF, EPUB and Kindle. Book excerpt: In an age where the amount of data collected from brain imaging is increasing constantly, it is of critical importance to analyse those data within an accepted framework to ensure proper integration and comparison of the information collected. This book describes the ideas and procedures that underlie the analysis of signals produced by the brain. The aim is to understand how the brain works, in terms of its functional architecture and dynamics. This book provides the background and methodology for the analysis of all types of brain imaging data, from functional magnetic resonance imaging to magnetoencephalography. Critically, Statistical Parametric Mapping provides a widely accepted conceptual framework which allows treatment of all these different modalities. This rests on an understanding of the brain's functional anatomy and the way that measured signals are caused experimentally. The book takes the reader from the basic concepts underlying the analysis of neuroimaging data to cutting edge approaches that would be difficult to find in any other source. Critically, the material is presented in an incremental way so that the reader can understand the precedents for each new development. This book will be particularly useful to neuroscientists engaged in any form of brain mapping; who have to contend with the real-world problems of data analysis and understanding the techniques they are using. It is primarily a scientific treatment and a didactic introduction to the analysis of brain imaging data. It can be used as both a textbook for students and scientists starting to use the techniques, as well as a reference for practicing neuroscientists. The book also serves as a companion to the software packages that have been developed for brain imaging data analysis. An essential reference and companion for users of the SPM software Provides a complete description of the concepts and procedures entailed by the analysis of brain images Offers full didactic treatment of the basic mathematics behind the analysis of brain imaging data Stands as a compendium of all the advances in neuroimaging data analysis over the past decade Adopts an easy to understand and incremental approach that takes the reader from basic statistics to state of the art approaches such as Variational Bayes Structured treatment of data analysis issues that links different modalities and models Includes a series of appendices and tutorial-style chapters that makes even the most sophisticated approaches accessible

Download or read book Craniofacial Development The Tissue and Molecular Interactions That Control Development of the Head written by Philippa H. Francis-West and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Craniofacial development is a multistep and intricate process initially involving a number of inductive interactions that control neural and neural crest development, which are followed by a series of epithelial-mesenchymal interactions that control outgrowth, patterning, and skeletal differentiation. Certain aspects of craniofacial development are unique developmental processes in higher vertebrates. First, in higher vertebrates the cranial neural crest, in contrast to the trunk neural crest, gives rise to the skeletal structures. These skeletal elements include those comprising mem brane bone and secondary cartilage, which with the exception of the clavicle are tissue types found exclusively in the head in higher vertebrates. Second, with the exception of the tongue, the origin of the musculature is distinct from other regions of the body. The body and tongue muscles are formed from the segmented epithelial somites whilst the head musculature is formed from unsegmented paraxial and prechordal mesoderm. Furthermore, the signalling cascades that control myogenic differentia tion appear to be distinct as determined by gene expression and the response of myogenic cells to growth factors. Finally, the neurogenic placodes, which give rise to the sensory organs and some cranial ganglia, are only found in the head. Over recent years, there have been significant advances in our knowledge of the molecular proc esses that control craniofacial development in a number of animal models. This has given insight into the genes that control many aspects of head development from the initial induction of the head to the final stages of differentiation.

Download or read book Behavioral Inhibition written by Koraly Pérez-Edgar and published by Springer. This book was released on 2018-09-22 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines three decades of research on behavioral inhibition (BI), addressing its underlying biological, psychological, and social markers of development and functioning. It offers a theory-to-practice overview of behavioral inhibition and explores its cognitive component as well as its relationship to shyness, anxiety, and social withdrawal. The volume traces the emergence of BI during infancy through its occurrences across childhood. In addition, the book details the biological basis of BI and explores ways in which it is amenable to environmental modeling. Its chapters explore the neural systems underlying developmental milestones, address lingering questions (e.g., limitations of studying BI in laboratory settings and debatable benefits of self-regulatory processes), and provide recommendations for future research. Key areas of coverage include: Animal models of behavioral inhibition. Social functioning and peer relationships in BI. Attention mechanisms in behavioral inhibition. BI and associative learning of fear. Behavioral inhibition and prevention of internalizing distress in early childhood. The relations between BI, cognitive control, and anxiety. Behavioral Inhibition is a must-have resource for researchers, clinicians, scientist-practitioners, and graduate students across such fields as developmental psychology, psychiatry, social work, cognitive and affective developmental neuroscience, child and school psychology, educational psychology, and pediatrics.

Download or read book The Cambridge Handbook of Consciousness written by Philip David Zelazo and published by Cambridge University Press. This book was released on 2007-05-14 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Handbook of Consciousness is the first of its kind in the field, and its appearance marks a unique time in the history of intellectual inquiry on the topic. After decades during which consciousness was considered beyond the scope of legitimate scientific investigation, consciousness re-emerged as a popular focus of research towards the end of the last century, and it has remained so for nearly 20 years. There are now so many different lines of investigation on consciousness that the time has come when the field may finally benefit from a book that pulls them together and, by juxtaposing them, provides a comprehensive survey of this exciting field. An authoritative desk reference, which will also be suitable as an advanced textbook.
Download or read book Descartes Error written by Antonio Damasio and published by Penguin. This book was released on 2005-09-27 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since Descartes famously proclaimed, "I think, therefore I am," science has often overlooked emotions as the source of a person’s true being. Even modern neuroscience has tended, until recently, to concentrate on the cognitive aspects of brain function, disregarding emotions. This attitude began to change with the publication of Descartes’ Error in 1995. Antonio Damasio—"one of the world’s leading neurologists" (The New York Times)—challenged traditional ideas about the connection between emotions and rationality. In this wondrously engaging book, Damasio takes the reader on a journey of scientific discovery through a series of case studies, demonstrating what many of us have long suspected: emotions are not a luxury, they are essential to rational thinking and to normal social behavior.
