This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.

The Cerebral Code is a new understanding of how Darwinian processes could operate in the brain to shape mental images in only seconds, starting with shuffled memories no better than the jumble of our nighttime dreams, but evolving into something of quality, such as a sentence to speak aloud. Jung said that dreaming goes on continuously but you can't see it when you are awake, just as you can't see the stars in the daylight because it is too bright. Calvin's is a theory for what goes on, hidden from view by the glare of waking mental operations, that produces our peculiarly human type of consciousness with its versatile intelligence. As Piaget emphasized in 1929, intelligence is what we use when we don't know what to do, when we have to grope rather than using a standard response. Calvin tackles a mechanism for doing this exploration and improvement offline, as we think before we act or practice the art of good guessing. Surprisingly, the subtitle's mosaics of the mind is not a literary metaphor. For the first time, it is a description of a mechanism of what appears to be an appropriate level of explanation for many mental phenomena, that of hexagonal mosaics of electrical activity that compete for territory in the association cortex of the brain. This two-dimensional mosaic is predicted to grow and dissolve much as the sugar crystals do in the bottom of a supersaturated glass of iced tea. A Bradford Book

This is the third edition of the translation, by Laurence Garey, of "Vergleichende Lokalisationslehre der Grosshirnrinde" by Korbinian Brodmann, originally published by Barth-Verlag in Leipzig in 1909. It is one of the major "classics" of the neurological world. Even today it forms the basis for so-called "localisation" of function in the cerebral cortex. Brodmann's "areas" are still used to designate functional regions in the cortex, the part of the brain that brings the world that surrounds us into consciousness, and which governs our responses to the world. For example, we use "area 4" for the "motor" cortex, with which we control our muscles, "area 17" for "visual" cortex, with which we see, and so on. This nomenclature is used by neurologists and neurosurgeons in the human context, as well as by experimentalists in various animals. Indeed, Brodmann's famous "maps" of the cerebral cortex of humans, monkeys and other mammals must be among the most commonly reproduced figures in neurobiological publishing. The most famous of all is that of the human brain. There can be few textbooks of neurology, neurophysiology or neuroanatomy in which Brodmann is not cited, and his concepts pervade most research publications on systematic neurobiology. In spite of this, few people have ever seen a copy of the 1909 monograph, and even fewer have actually read it! There had never been a complete English translation available until the first edition of the present translation of 1994, and the original book had been almost unavailable for 50 years or more, the few antiquarian copies still around commanding high prices. As Laurence Garey, too, used Brodmann’s findings and maps in his neurobiological work, and had the good fortune to have access to a copy of the book, he decided to read the complete text and soon discovered that this was much more than just a report of laboratory findings of a turn-of-the-twentieth-century neurologist. It was an account of neurobiological thinking at that time, covering aspects of comparative neuroanatomy, neurophysiology and neuropathology, as well as giving a fascinating insight into the complex relationships between European neurologists during the momentous times when the neuron theory was still new.

This book offers detailed guidance on the diagnostic use of cerebral angiography based on precise description of the angiographic appearances of normal anatomy and pathological conditions. In this third edition, every chapter has been thoroughly revised and enlarged to reflect new knowledge and experiences, and more attention is paid to the correlations between anatomopathological findings and clinical manifestations. Beyond explaining the diagnostic value of cerebral angiography, a key aim is to equip readers with the precise knowledge of the anatomy of cerebral vessels required for optimal application of endovascular therapy of pathologies involving the arteries and veins of the brain. As in preceding editions, the book is divided into two parts. The first part describes the normal anatomy, with attention to morphological aspects, embryological development, function, and vascular territories. The intraorbital and extracranial vascularization is also fully considered. The knowledge provided will serve as a sound basis for the correct interpretation of pathological processes and their clinical significance, as covered in depth in the second part of the book.

When a child has a health problem, parents want answers. But when a child has cerebral palsy, the answers don't come quickly. A diagnosis of this complex group of chronic conditions affecting movement and coordination is difficult to make and is typically delayed until the child is eighteen months old. Although the condition may be mild or severe, even general predictions about long-term prognosis seldom come before the child's second birthday. Written by a team of experts associated with the Cerebral Palsy Program at the Alfred I. duPont Hospital for Children, this authoritative resource provides parents and families with vital information that can help them cope with uncertainty. Thoroughly updated and revised to incorporate the latest medical advances, the second edition is a comprehensive guide to cerebral palsy. The book is organized into three parts. In the first, the authors describe specific patterns of involvement (hemiplegia, diplegia, quadriplegia), explain the medical and psychosocial implications of these conditions, and tell parents how to be effective advocates for their child. In the second part, the authors provide a wealth of practical advice about caregiving from nutrition to mobility. Part three features an extensive alphabetically arranged encyclopedia that defines and describes medical terms and diagnoses, medical and surgical procedures, and orthopedic and other assistive devices. Also included are lists of resources and recommended reading.
