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 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.
First Published in 1987. Routledge is an imprint of Taylor &
Francis, an informa company.
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.
