Covering both the applications and the related theory, A Concise Guide to Intraoperative Monitoring provides a general but comprehensive introduction to IOM. Unlike existing texts that typically report the results of specific studies, this book presents comprehensive coverage of the entire procedure, as well as the specific protocols used in hospital practice, examples of typical recordings, possible problems, and recommended solutions. At the end of each chapter the author poses several questions for review. These questions help technologists and medical residents in their preparation for the board exams. Taken together, these features make the book an ideal reference or training manual.

A Concise Guide to Intraoperative Monitoring begins by discussing the basic principles underlying the generation of bioelectrical signals. It then describes the electronic equipment and the various electrophysiological procedures involved in IOM. From this foundation, the book gradually advances to more specific topics, such as surgical procedures, neuronal structures at risk, the optimum combinations of tests to administer, and the proper interpretation of test results. The material
also provides you with a background on general anesthesia and analyzes the effects of various drugs on electrophysiological recordings. A Concise Guide to Intraoperative Monitoring also discusses the proper placement of stimulation and recording electrodes, as well as intervention strategies and equipment troubleshooting.

Fifty Years of Magnetoencephalography celebrates the first half century of research in and clinical applications of magnetoencephalography (MEG). It catalogs and documents its evolution as a means of imaging the ongoing activity of the brain and the activation of particular neuronal networks within it that mediate sensory motor and higher functions like language. The volume's first section looks at the discovery of MEG and its first tentative applications by three of its founders. The following sections detail the rapid progress in the development of the instrumentation necessary for recording noninvasively the magnetic signals on the head that are associated with the brain activity; improvements in the techniques for analyzing the magnetic signals and reconstructing, on their basis, the functional images of brain activity; and improvements in our understanding of the nature and significance of those signals. Subsequent sections of the book detail the main clinical applications of MEG in localizing brain areas that contain sources of epileptiform activity and areas encompassing parts of functional networks essential for motor and sensory function as well as for language that have become an essential part of planning for brain surgery in many epilepsy and tumor surgery centers around the world. In addition, several chapters describe the most current efforts aiming at expanding the utility of MEG in clinical diagnosis and theoretical research.

This is the first volume to explore the field of clinical magnetoencephalography (MEG) and magnetic source imaging (MSI), the techniques measuring the magnetic fields generated by neuronal activity in the brain. Describing the empirical knowledge gained during the last two decades, this book will serve as a basis for the training of clinicians and scientists entering this new and exciting field. The book covers the methods for recording MEG and performing MSI in a clinical setting and includes practical examples of data collection and analysis. It explains why MEG should be used in the evaluation and treatment of patients being considered for epilepsy surgery, concluding with a section describing the potential for future applications of these methods. This is essential reading for graduate students in clinical neuroscience, residents in neurology and psychiatry, neuroradiology and neurosurgery, specialists in neurophysiology and epilepsy, and clinicians in a wide range of related brain sciences.

This concise but comprehensive text provides a systematic account of the memory disorders, whether they result from psychological stress, traumatic injury, stroke, or degenerative disease of the brain. The major amnesia syndromes are covered in consistently organized chapters that give a clear description of the clinical signs and symptoms, predisposing factors, prevalence and prognosis, pathophysiology to the extent that it is known, diagnostic approaches including tests used to evaluate the disorders, and therapeutic efforts. The book's emphasis is on facts rather than theory, and readers from a variety of disciplines will appreciate its clear, jargon-free, well-organized assessment of the state of knowledge about the memory disorders. These disciplines include neurobiology, neuropsychology, psychiatry, cognitive neuroscience, rehabilitation medicine, and gerontology. Even theorists will find the book useful since any theory of memory and its neurophysiological mechanisms must be constrained by the facts of amnesia if it is to be considered complete.
The book's clearcut scheme of organization will enhance its value and user-friendliness. It divides the amnesias into three types: progressive, permanent, and transient. The first type includes amnesias associated with neurodegenerative diseases such as Alzheimer's and Parkinson's, and with vascular dementias, contrasting them with memory decline resulting from normal aging. The second type consists of classic amnesic syndromes associated with limbic lesions of various etiologies such as Korsakoff's encephalopathy and traumatic brain injuries. The third type includes transient global, transient epileptic, and ECT-induced amnesias aswell as the reversible psychogenic amnesias associated with dissociative and fugue states. These discussions are preceded by two introductory chapters that define the mnemonic and amnesic phenomena, classify the various memory systems and functions, and describe the putative brain circuitry underlying these functions, including molecular mechanisms, neurotransmitter systems, and the effects of stress-related hormones and drugs, with the aid of magnetic resonance images and anatomical drawings.

The author explores the question of the nature of emotion by critically examining three theoretical approaches - the somatic or peripheralist, the cerebrocentric, and the cognitive. In finding the somatic approach superior to the others, the author explicitly challenges current conceptions regarding the nature of emotion. Giving particular emphasis to the works of William James, the author recasts the somatic theory in detail and demonstrates how it best fits the available clinical experimental data. Written in jargon-free language, the book presents to specialists and non-specialists alike an overview of this topic.
