Book excerpt: Strychnine and picrotoxin were tested as possible antagonists of two puta tive inhibitory transmitters in the retina: taurine and GABA, Strychnine was shown to antagonize the depressive action of taurine on the ERG b-wave, but it did not affect the depressive action of GABA. Conversely, picrotoxin had no effect on the depressive action of taurine on the ERG b-wave, but it antagonizes to some extent the depressive effect of GABA. These data, as well as those obtained through recording tectal evoked responses, lead to the conclusion that taurine and GABA do not act in the same way in retinal inhibitory synaptic transmission.

Available in PDF, EPUB and Kindle. Book excerpt: The 13th biennial Symposium of the International Research Group on Colour Vision Deficiencies was held from 27 July to 30 July, 1995, in the splendidjin de siecle Theatre Saint Louis, in Pau, France. A total of 80 papers and posters were presented during the four days, of which 56 have been selected for inclusion in this volume. Each has been reviewed by two of the Editors. Additionally, in numerous cases in which specialized knowledge was called for the Editors asked for external help; their assistance is acknowledged below. While Pau now exists largely on agriculture and, more recently, oil extraction and refining, a century ago it was a winter resort that rivalled Cannes and Nice; indeed, Baedeker judged the air of Pau to be preferable for those of a nervous disposition. Pau and the surrounding Beam district are rich in history and have close ties to the Basque region, both of which were exploited brilliantly by the local organizers, Doctors Jean and Veronique Lied, to introduce the partici pants to the gastronomy and traditions of the region. The Committee of the IRGCVD owe a great debt of gratitude to the external reviewers, Oscar Estevez, Karl Gegenfurtner, Gunilla Haegerstrom-Portnoy, RL. Hilz, John Krauskopf, Anne Kurtenbach, Barry B.

Available in PDF, EPUB and Kindle. Book excerpt: Professor GOSTA KARPE GOSTA KARPE was born in Vadstena, Sweden, 1908. His medical education started in 1927 at the Karolinska Institute in Stockholm During his study he worked parttime in the department of physiology. KARPE served as a resident in the ophthalmological department of Serafiner lasarettet from 1937 till 1941. That year, the university eye clinic was transferred to the newly built Karolinska Sjukhuset, where KARPE became assistant-head of the out-patient department, and lecturer in ophthalmology. In 1949 he was appoin ted professor in ophthalmology at the Karolinska Institute and head of the department of ophthalmology at Karolinska Sjukhuset. KARPE received his doctor degree in 1945 upon completion of his thesis: 'The basis of clinical electroretinography'. This original work opened up a completely new field of clinical investigation. Soon Swedish and foreign pupils flocked into his department to study his new method, a technique at present accepted as an indispensable tool in ophthalmic practice. Since 1945 his work as well as that of his pupils have been devoted mainly to this field of research.

This book was released on 2012-12-06 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigators and clinicians researching and applying electrophysiologic phenomena of the eye, met for the XXth Symposium of the International Society for Clinical Electrophysiology of Vision in Iowa City, Iowa, under the auspices of the University of Iowa and supported by the Department of Ophthalmology, headed by Professor Frederick C. Blodi. Two main topics were discussed: I) Electro-oculography and other slow potentials: the phenomenon, origin, analysis, and clinical diagnosis, and 2) Microprocessor applications for computer-assisted recording and analysis of electro visual phenomena. Unusual and challenging diagnostic problems were presented during one evening session. The interest and lively audience participation indicated a need for such an unrehearsed debate. Drs. H.W. Skalka, H. Nakano, H.S. Thompson, A.J. Packer, J.A. Parker, H.E. Kolder, V.M. Hermsen, M.L. Wolf, and Mr. A.1. Mallinson presented case reports and are herewith recognized for their contribution. No documentation is contained in the Proceedings. Several papers were read outside the main topics. Some material appears only as abstract. The highlight of the scientific program proved to be an improvised session on basic mechanisms of slow potentials from the eye. Dr. R.H. Steinberg and his collaborators, together with Dr. G. Niemeyer initiated this part of the program. It was enthusiastically received, provided an informal atmosphere, stimulated a lively discussion and exchanged pro found information. A novel feature of this volume is the addition of a cumulative index covering the Proceedings from the last ten ISCERG-ISCEV Symposia. Dr.

Download or read book Developmental Neurobiology of Vision written by R. D. Freeman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains summaries of most of the invited presentations given by lecturers and participants at the NATO Advanced Study Institute, "Develop mental Neurobiology of Vision," held in Rethymnon, Crete, Greece 18-27 Sep tember 1978. The purpose of this meeting was to enable a relatively small international group of scientists and students to hold discussions and to present their views on current problems in the field. It was intended that the results of the exchanges would be conveyed to others in the native countries of the parti cipants. An attempt was made to obtain broad representation of disciplines within the area of the Institute and this is reflected in the diversity of the chapters in this book. Considerable interest has been generated in recent years concerning the development and plasticity of vision. Perhaps not unexpectedly, along with the high level of activity in this field, there have been so me controversial findings.

Download or read book Eye Movements written by Dennis F. Fisher and published by Routledge. This book was released on 2017-03-27 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1981, this volume represents the edited proceedings of the third symposium on eye movements and behaviour sponsored by the US Army Human Engineering Laboratory. The conference, titled "The Last Whole Earth Eye Movement Conference" was held in Florida in February 1980. As the conference approached, seizure of the American hostages by the Iranian militants, the Russian invasion of Afghanistan, and the uncertain economic outlook around the world made it appear as though the title was a self-fulfilling prophecy. But the meeting proved highly successful and people throughout the world seemed to be adapting to the stresses of international tension, making the possibility of subsequent meetings more likely. The present volume is intended to serve as a complementary text to the earlier texts Eye Movements and Psychological Processes (Monty & Senders, 1976) and Eye Movements and the Higher Psychological Functions (Senders, Fisher & Monty, 1978), rather than a revision and update of them.

Download or read book Continuity of Neural Functions from Prenatal to Postnatal Life written by Heinz F. Prechtl and published by Cambridge University Press. This book was released on 1984 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Is the human neonate indeed "physiological premature," as has been frequently stated? How does human neural development compare with that of other primate species? Is early human development a gradual unfolding of neural mechanisms from prenatal to postnatal life, or does it show rapid transformations at particular ages? The aim of this book is to answer these and similar questions about the functional repertoire of the human fetus, neonate, and young infant. Two main theoretical concepts are considered: first, the relationship between neural maturation and the duration of pregnancy and second, the existence of ontogenetic adaptations. Surveys and findings relevant to these concepts are provided by experts from various disciplines involved in research on fetal and preterm development and on the first three months of postnatal life. This book differs from many others summarizing descriptive knowledge of the field by emphasizing new theoretical concepts of early functional development. Recent ultrasound studies of the fetus have contributed greatly to this new approach, which has clear implications for the assessment and care of young infants. This thought-provoking book will be of interest to developmental neurologists, pediatricians and obstetricians, as well as to developmental psychologists and physical anthropologists.

Available in PDF, EPUB and Kindle. Book excerpt: In the spring of 1987, I was in Havana, Cuba, where I was participating in planning a large-scale longitudinal study of the neurophysiological, neurochemical, and behavioral characteristics of cohorts of patients with cerebrovascular disease, depression, senile dementia, schizophrenia, or learning disabilities; and also part of this study were their first-degree blood relatives. This study was the outgrowth of a long-term project on the practical application of computer methods for the evaluation of brain electrical activity related to anatomical integrity, maturational development, and sensory, perceptual;·-and cognitive processes, especially in chil dren. For many years, that project had been supported by the United Nations Development Program (UNDP), the National Scientific Research Center of Cuba (CNIC), and the Ministries of Public Health and of Education of Cuba. Since its inception, I had served as a technical advisor to the UNDP project. When the project began, I became acquainted with Dr. Jose M. Miyar Barrueco, who was at that time the Rector of the Medical School of the University of Havana. Because of his keen interest in the new computer technology and its potential utility in developing countries, we met from time to time during my visits. These occasional meetings continued after he became Secretary of the Cuban Council of State, so that he could remain apprised of progress and problems with which he might help.

Available in PDF, EPUB and Kindle. Book excerpt: From the 98 presentations of the XIIth Symposium on Colour Vision Deficiencies, 61 were selected after peer review and revision by the authors. In addition to these contributions this volume contains a cumulative index to all authors in the IRGCVD proceedings since the first one in 1968, including the present volume. The contents include contributions on basic questions of anatomical and electrophysiological organisation of the neural pathways underlying colour vision; and on ways in which disturbances of these pathways can produce acquired colour vision deficiencies. Further contributions deal with genetics and congenital red--green colour deficiencies and colour vision testing. The resulting publication contains much of interest to basic vision scientists as well as to specialists in colour vision deficiencies.

Available in PDF, EPUB and Kindle. Book excerpt: Since its inception, the International Research Group on Colour Vision Deficiencies (IRGCVD) has followed the policy that the Symposium Pro ceedings should be as close as possible to a complete record of the scientific content of the meeting. This policy has the advantage of providing an accurate picture of the current state of the art in research on color vision deficiencies, but it also has the disadvantage that papers typically span a wide range of quality. In this volume, however, we have instituted a system of peer review in an effort to enhance scientific quality as much as possible while continuing our past policy of publishing all submitted manuscripts. In addition to being edited for English composition and grammar, each of the papers included here has been carefully reviewed by an IRGCVD member selected for his or her expertise in the specific topic of the paper. Reviewers were instructed to include in their comments suggestions for improvement rather than recom or rejection. In our opinion, this review process mendations for publication has resulted in substantial improvement of many of the articles and has enhanced the value of the publication. We are pleased to acknowledge the efforts of our reviewers and offer them our sincere thanks for their important contributions to Colour Vision Deficiencies X. The Editors B. Drum, J. D.
