This book is devoted to the description of agenesis of the corpus callosum, a congenital malformation of midline structures in the brain that may be regarded as a natural model of the "split-brain. " First reported by Rei! in 1812, this anomaly has since been described by several investigators. Interest in this malformation was revived in the 1970s by studies of interhemispheric transfer in Bogen and Vogel's commissurotomized patients and the subsequent findings by Sperry that acallosal patients were devoid of the typical disconnection deficits found in patients with surgical transection of the corpus callosum. Since this seminal work, the bulk of neuropsychological research on callosal agenesis has focused on the particulars of interhemispheric transfer and integration. An ever-growing literature has emerged on the subject, attempting to specify the extent and limits of neural plasticity in a nervous system that has evolved in the absence of the most important interhemispheric pathway. Whilst callosal agenesis proves to be an excellent model of cerebral plasticity, it has to be pointed out that this anomaly is often associated with other malformations and neurological diseases that may result in different degrees of mental retardation or other cognitive and sensorimotor deficits. In this context, neurological research on callosal agenesis has concentrated on the description of various syndromes associated with this pathology as well as on the attempt to specify its neurobehavioral manifestations.

This book has brought together leading investigators who work in the new arena of brain connectomics. This includes ‘macro-connectome’ efforts to comprehensively chart long-distance pathways and functional networks; ‘micro-connectome’ efforts to identify every neuron, axon, dendrite, synapse, and glial process within restricted brain regions; and ‘meso-connectome’ efforts to systematically map both local and long-distance connections using anatomical tracers. This book highlights cutting-edge methods that can accelerate progress in elucidating static ‘hard-wired’ circuits of the brain as well as dynamic interactions that are vital for brain function. The power of connectomic approaches in characterizing abnormal circuits in the many brain disorders that afflict humankind is considered. Experts in computational neuroscience and network theory provide perspectives needed for synthesizing across different scales in space and time. Altogether, this book provides an integrated view of the challenges and opportunities in deciphering brain circuits in health and disease.

Among physicians responsible for the care of human infants born with a malformed nervous system, there is a compelling need for an accessible synthesis and summary of modern embryological concepts of dysgenesis. This book integrates the morphological, clinical, neurological, genetic, neurophysiological and imaging aspects of cerebral malformation in the context of a lucid embryological explanation. Rather than presenting a catalog of anatomical abnormalities, the text focuses on pathogenesis and clinical aspects. Anatomical appearances are described by imaging in life, while neuropathological features are derived from findings at autopsy. Embryological explanations are identified as documented observation or speculation. Among the topics covered are encephaloceles as a disorder of the primitive streak and node; cerebral hypoplasia as a precocious differentiation of the ependyma before all mitotic generations of the neuroepithelial cells are completed; holosprosencephaly as a disorder of the lamina terminalis; agenesis of the corpus callosum as a failure of programmed glial cell death in the callosal plate in preparation for axonal growth cone passage; subcortical heterotopia as an arrest of late neuroblast migrations due to retraction of radial glial guide fibers from the pial surface of the brain. The literature is exhaustively reviewed and supplemented by the author's own experience. The book is richly illustrated throughout.

Handbook of Fetal Medicine provides a concise and practical guide to the modern management of normal pregnancy and the at-risk fetus. Comprehensive in scope, in an easy-to-use format, the book provides guidance on a wide range of conditions, best practice management strategies and treatment options in maternal-fetal medicine. Each system-based chapter has a brief introduction on embryology and discusses the key genetic developments and relevant developmental abnormalities. The book begins by addressing genetic disorders such as Down syndrome, and goes on to consider skeletal and bodily system abnormalities. All key management points are highlighted and data on long-term outcomes are provided. This book will appeal to maternal-fetal medicine specialists, subspecialty trainees, obstetricians and midwives as a useful practical reference tool in daily practice. It is particularly suitable for trainees in Obstetrics & Gynaecology preparing for the post graduate examinations.
