Book Description
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.

Book Description
I am greatly pleased and honoured to have been invited by Professor HENRI DUVERNOY to contribute a foreword to this book, especially since I became aware of the magnitude of his researches upon the cerebral vessels only a few years ago. These researches have, in fact, been pursued for almost two decades, beginning with a study of the hypophyseal vessels in 1958. More recently he has published a monograph entitled "The Superficial Veins of the Human Brain", and those who know this book will have noted the succinct clarity of the descriptive text and the superb quality ofthe photographs with which this chef-d'oeuvre is illustrated. This outstanding contribution to intimate detail of the superficial vascularization of the brainstem is now complemented by a second volume on internal angio-architec ture. As before, the emphasis is upon direct photographic evidence, and again the photographs are of a quality which must be almost unsurpassable. Those who are familiar with the technique of vascular injection of the brain and of the diffi culties of micro-anatomical identification, will applaud the excellence of Professor DUVERNOY' s preparations. Even the smallest named nuclei and fasciculi of nerve fibres are displayed most effectively. From study of these details, in conjunction with other descriptions of brain stern vessels (to which Professor DUVERNOY has hirnself contributed much), the vascular supply and drainage of all the recognised entities in the brain stern can be deduced.

Book Description
Compared to its predecessor, this new edition also includes figures relating to the superficial venous network of the brain stem, thus giving readers a more precise and complete view of the superficial brainstem vessels. It also includes a special study on the pineal or collicular region and a correlation between the vascular territories and MRI views of brainstem vascular diseases. The book provides a complete view of the vascularization of the brainstem in humans including the arteries, veins and capillary network, for the study of brainstem pathology.

Book Description
Learn from key leaders in the field of neurosurgery with the practical guidance presented in this first-of-its-kind resource. Complications in Neurosurgery uses a case-based format to explore complications across the full range of commonly performed neurosurgical procedures. As you review dozens of up-to-date, real-life cases, you’ll become better equipped to identify pitfalls ahead of time and have the knowledge to handle difficult situations that arise during surgery. Presents commonly encountered cases provided by experienced neurosurgeons in all areas of this challenging specialty. Includes high-quality photographs, images, and dynamic video to ensure complete visual understanding of the procedures. Uses a consistent, easy-to-read format throughout, covering a wide range of surgeries including general neurosurgery and cranial complications, as well as spinal and peripheral complications. Numerous videos depict possible complications for each type of surgery; for example, Complications of Cerebral Bypass Surgery includes videos showing how to obtain venous hemostasis without risking injury to the STA, how to manage atheroma within the donor vessel, and how to manage intraoperative occlusion of the bypass.

Book Description
Peripheral and Cerebrovascular Intervention draws upon experts from diverse fields to provide readers with a comprehensive foundation for understanding and performing endovascular procedures—from the basic steps to the most current and advanced techniques. Individual chapters focus on primary intervention sites, including lower extremity, renal/mesenteric, subclavian/upper extremity, carotid/vertebral, intracranial and venous interventions. Additionally, chapters covering critical limb ischemia and abdominal and thoracic aortic aneurysms are included. By incorporating valuable clinical information, such as indications, contraindications, complications and discussions of surgical techniques and procedures, this book is a valuable resource for the busy practitioner and will be of interest to all interventional and general cardiologists, radiologists and neurologists; vascular surgeons; internists and residents and fellows.

Book Description
One of the major challenges of modern neuroscience is to define the complex pattern of neural connections that underlie cognition and behaviour. This atlas capitalises on novel diffusion MRI tractography methods to provide a comprehensive overview of connections derived from virtual in vivo tractography dissections of the human brain.

Book Description
This book is unique in that it provides the reader with the most up-to-date terminology used to describe the human nervous system (central and peripheral) and the related sensory organs, i.e., the Terminologia Neuroanatomica (TNA), the official terminology of the IFAA (International Federation of Associations of Anatomists). The book provides a succinct but detailed review of the neuroanatomical structures of the human body and will greatly benefit not only various specialists such as (neuro)anatomists, neurologists and neuroscientists, but also students taking neuroanatomy and neuroscience courses. The book offers a high yield, combined presentation of neuroanatomical illustrations and text and provides the reader a ‘one-stop source’ for studying the intricacies of the human nervous system and its sensory organs. It includes an alphabetical list of official English terms and synonyms with the official Latin terms and synonyms from the TNA. With regard to the entries, the name of the item in standardized English is provided, followed by synonyms and the official TNA Latin term, Latin synonyms and eponyms, a short description and in many cases one or more illustrations. To facilitate the use of illustrations, certain entries such as the gyri or sulci of the cerebral cortex are presented together with extensive cross-references. Terms that form part of a certain structure (such as the amygdaloid body, the thalamus and the hypothalamus) are listed under the respective structure. Segments and branches of arteries are discussed under the main artery, for example the A1–A5 segments under the anterior cerebral artery. Most nerves can be found following their origin from the brachial, cervical and lumbosacral plexuses. However, the major nerves of the limbs are discussed separately, as are the cranial nerves. Nuclei can be found by their English name or under Nuclei by their eponym.
