This book was released on 2024-09-19 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a remarkable time to study the vertebrate retina, either as a model for the brain or to understand the first steps in vison. We have known about the diversity of retinal neurons and glia for more than one hundred years, and we are now extending these findings and making new discoveries about retinal cell types by analyzing gene expression in single cells. We have made significant progress toward our ultimate goals of describing the neural circuits in the retinas at the level of connections between identified populations of neurons and understanding neuronal and glial cell function at the molecular level. We have also made great strides toward understanding retinal development and the etiology of retinal diseases. Physiologists are now using more realistic stimuli and modern analytical methods to analyze the mechanisms underlying light responses of retinal neurons, and this has led to more accurate computational models of neural circuits in the retina. My colleague at the McGovern Medical School in Houston, Steve Massey, has made many important contributions to this field, both as a researcher and as a mentor, and he is planning his retirement. Judith Ogilvie, Christophe Ribelayga, Chai-an Mao and I will dedicate this issue to him and plan to publish some of his latest work. This Research Topic will include mini-reviews and brief communications about neurons and neural circuits in vertebrate retinas. The scope will be very broad, including anatomical, physiological, psychophysical and computational approaches to this topic. Potential topics include, but are not restricted to: • Development. morphology and synaptic connections of neuronal types • Light responses, spontaneous activity and membrane properties of retinal neurons • Gene expression and other aspects of cell biology of identified retinal neurons • Release of neurotransmitters and modulators and their effects in the retina • Structure and function of electrical synapses in the retina • Neural circuits that mediate responses to color, contrast and movement • Roles of neuroglia in retinal development, homeostasis and light responses • Contributions of neural circuits in the retina to visual perception • Evolution of neuronal types and neural circuits in the retina • Novel techniques for analyzing retinal neurons and neural circuits • Non-invasive methods to analyze retinal structure and function • Etiology of retinal diseases and potential new therapies • Directions for future research on the vertebrate retina

This book was released on 2013-03-08 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vertebrate retina has a form that is closely and clearly linked to its func tion. Though its fundamental cellular architecture is conserved across verte brates, the retinas of individual species show variations that are also of clear and direct functional utility. Its accessibility, readily identifiable neuronal types, and specialized neuronal connectivity and morphology have made it a model system for researchers interested in the general questions of the genet ic, molecular, and developmental control of cell type and shape. Thus, the questions asked of the retina span virtually every domain of neuroscientific inquiry-molecular, genetic, developmental, behavioral, and evolutionary. Nowhere have the interactions of these levels of analysis been more apparent and borne more fruit than in the last several years of study of the develop ment of the vertebrate retina. Fields of investigation have a natural evolution, rdoving through periods of initial excitement, of framing of questions and controversy, to periods of synthesis and restatement of questions. The study of the development of the vertebrate retina appeared to us to have reached such a point of synthesis. Descriptive questions of how neurons are generated and deployed, and ques tions of mechanism about the factors that control the retinal neuron's type and distribution and the conformation of its processes have been posed, and in good part answered. Moreover, the integration of cellular accounts of development with genetic, molecular, and whole-eye and behavioral accounts has begun.

Available in PDF, EPUB and Kindle. Book excerpt: "Who would believe that so small a space could contain the images of all the universe?" Leonardo da Vinci The last years of the 20th century have found the discipline of Developmental Biology returning to its original position at the forefront of biological re search. This progress can be attributed to the burgeoning knowledge base on molecules and gene families, and to the power of the molecular genetic ap proach. Topping the list of organ systems which have provided the most significant advances would have to be the eye. The vertebrate eye was one of the classic embryologic models, used to demonstrate many important prin ciples, including the concepts of inductive tissue interactions first put forth in the early 1900s. Within the last decade of this century, a return to some of the old questions with the new approaches has put eye development back into the limelight. I find this a highly appropriate topic for a book which aims to spark research for the new millennium. We begin with a chapter that discusses the anatomy of eye development, providing the basic reference information for the chapters that follow. A novel aspect of this introduction is the connection made between develop mental strategies and the eye's optical function. What also emerges from this chapter is the number of important eye structures that have barely been touched by the modern developmental biologist. Work on cornea and ante rior chamber development has lagged behind lens and retina.

Download or read book Retinal Development written by Evelyne Sernagor and published by Cambridge University Press. This book was released on 2012-11-29 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: This advanced text, first published in 2006, takes a developmental approach to the presentation of our understanding of how vertebrates construct a retina. Written by experts in the field, each of the seventeen chapters covers a specific step in the process, focusing on the underlying molecular, cellular, and physiological mechanisms. There is also a special section on emerging technologies, including genomics, zebrafish genetics, and stem cell biology that are starting to yield important insights into retinal development. Primarily aimed at professionals, both biologists and clinicians working with the retina, this book provides a concise view of vertebrate retinal development. Since the retina is 'an approachable part of the brain', this book will also be attractive to all neuroscientists interested in development, as processes required to build this exquisitely organized system are ultimately relevant to all other parts of the central nervous system.

Download or read book The Visual System in Vertebrates written by F. Crescitelli and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vertebrate eye has been, and continues to be, an object of interest and of inquiry for biologists, physicists, chemists, psychologists, and others. Quite apart from its important role in the development of ophthalmology and related medical disciplines, the vertebrate eye is an exemplar of the ingenuity of living systems in adapting to the diverse and changing environments in which vertebrates have evolved. The wonder is not so much that the visual system, like other body systems, has been able to adapt in this way, but rather that these adaptations have taken such a variety of forms. In a previous volume in this series (VII/I) Eakin expressed admiration for the diversity of invertebrate photoreceptors. A comparable situation exists for the vertebrate eye as a whole and one object of this volume is to present to the reader the nature of this diversity. One result of this diversification of ocular structures and properties is that the experimental biologist has available a number of systems for study that are unique or especially favorable for the investigation of particular questions in visual science or neurobiology. This volume includes some examples of progress made by the use of such specially selected vertebrate systems. It is our hope that this comparative approach will continue to reveal new and useful preparations for the examination of important questions.

Available in PDF, EPUB and Kindle. Book excerpt: The strengths and failures of the American college, and why liberal education still matters As the commercialization of American higher education accelerates, more and more students are coming to college with the narrow aim of obtaining a preprofessional credential. The traditional four-year college experience—an exploratory time for students to discover their passions and test ideas and values with the help of teachers and peers—is in danger of becoming a thing of the past. In College, prominent cultural critic Andrew Delbanco offers a trenchant defense of such an education, and warns that it is becoming a privilege reserved for the relatively rich. In describing what a true college education should be, he demonstrates why making it available to as many young people as possible remains central to America's democratic promise. In a brisk and vivid historical narrative, Delbanco explains how the idea of college arose in the colonial period from the Puritan idea of the gathered church, how it struggled to survive in the nineteenth century in the shadow of the new research universities, and how, in the twentieth century, it slowly opened its doors to women, minorities, and students from low-income families. He describes the unique strengths of America’s colleges in our era of globalization and, while recognizing the growing centrality of science, technology, and vocational subjects in the curriculum, he mounts a vigorous defense of a broadly humanistic education for all. Acknowledging the serious financial, intellectual, and ethical challenges that all colleges face today, Delbanco considers what is at stake in the urgent effort to protect these venerable institutions for future generations.
