Imaging procedures have been used for many years and are becoming increasingly important in a number of medical disciplines. This is due to recent technological advances, primarily computerization. The meth ods employed in CNS diagnostics are collectively referred to as "neu roimaging" and include procedures for investigating both cerebral morphology and cerebral function, such as computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomogra phy (PET), and single-photon emission computed tomography (SPECT). Topographic mapping of electroencephalograms (EEG) and evoked potentials represents one of the functional procedures and per mits topographic imaging of EEG, evoked potentials, and magnetic fields. The latter application includes not only magnetic fields evoked by stimuli relating to different sensory modalities, but also endogenous and motor fields resulting from spontaneous brain magnetic activity, as recorded by magnetoencephalograms (MEG), the magnetic comple ment of the EEG. The advantage of recording electric and magnetic fields over other neuroimaging procedures is that these techniques are completely noninvasive and have extremely short analysis times (in the millisecond range). The aim of this book is to clarify the current state of this emerging technology, to assess its potential for substantive contributions to brain research, to delineate areas for further research and, over all, to envis age clinical applications in disciplines such as psychiatry, neurology, and neuropsychology.

Electroencephalography is truly an interdisciplinary endeavor, involving concepts and techniques from a variety of different disciplines. Included are basic physics, neuro physiology, electrophysiology, electrochemistry, electronics, and electrical engineer ing, as well as neurology. Given this interesting and diverse mixture of areas, the train ing of an EEG technician, a neurology resident, or an EEG researcher in the basics of clinical electroencephalography presents an uncommon challenge. In the realm of technology, it is relatively easy to obtain a technically adequate EEG simply by learning to follow a protocol and by correctly setting the various switches on the EEG machine at the right time. But experience has shown that the ability to obtain high-quality EEGs on a routine, day-to-day basis from a wide variety of patients requires understanding and knowledge beyond what is learned by rote. Likewise, knowledge above and beyond what is gained by simple participation in an EEG reading is necessary to correctly and comprehensively interpret the record. Such knowledge comes from an understanding of the basic principles upon which the practice of clinical EEG is founded - principles that derive from the various disciplines cited.

It had been difficult to find appropriate teaching material for students and newcomers to this field of brain electromagnetic topography. In part, this is due to the many disciplines involved, requiring some knowledge of the physical sciences, mathematics, neurophysiology and anatomy. It is my hope that this book will be found suitable for introducing interested workers to this exciting field. Advanced topics will not be covered, as there are many excellent texts available.

Cognitive electrophysiology is a very well established field utilizing new technologies such as bioelectric events-related potentials (ERP) and magnetic (ERF) recordings to pursue the investigation of mind and brain. Current research focuses on reviewing ERP/ERF findings in the areas of attention, language, memory, visual and auditory perceptual processing, emotions, development, and neuropsychological clinical damages. The goal of such research is basically to provide correlations between the structures of the brain and their complex cognitive functions.This book reviews the latest findings in the areas of attention, language, memory, visual and auditory perception, and brain damage research based primarily on research conducted using ERP recordings. Beyond just compiling the knowledge gained from ongoing research, the authors also identify outstanding problems in the field and predict future developments. - Provides an original post-cognitive theoretical approach to the investigation of the human mind and brain - Presents integrated view of the emotional and cognitive features as well as of developmental features of neurocognitive systems - Well-illustrated with elegant and original artwork that clarifies complex theoretical and methodological points throughout the text

Although cerebral dominance, the specialization of each side of the brain for different functions, was discovered in the 1860s, almost nothing was known for many years about its biological foundations, the study of which has undergone what can only be described as a revolution in the past decade and a half. Norman Geschwind and Albert Galaburda, two of the leaders of this new field, have assembled a distinguished group of investigators, each a pioneer in some aspect of the biology of dominance. The authors document human brain asymmetry at gross and microscopic levels in both adults and fetuses, its visualization in life by radiological methods, and its manifestation in brain waves. The evolutionary history of brain asymmetry over more than 300,000 years is shown in fossil skulls of humans and apes. In a dramatic reversal of older beliefs, asymmetry of anatomy, function, and chemistry has been demonstrated in many nonhuman species, and experiments have shown the role of hormones and other prenatal influences in the production of asymmetry. The surprising associations of non-right-handedness with twinning and immune disorders are discussed, as well as the asymmetrical malformation of the cortex in childhood dyslexia. This volume, combining scholarly authority and the excitement of the birth of a new discipline, will be welcomed by those to whom the implications of dominance are becoming evident--neuroscientists, neurologists, linguists, psychologists, experts in learning disorders, speech pathologists--and by specialists in nearly every branch of biology, medicine, and psychology.

From its discovery in 1929 by Hans Berger until the late 1960s, when sensory visual and auditory evoked potentials were dis covered and became popular, the EEG was the most important method of neurophysiological examination. W-ith the advent of computer technology in the 1980s, it became possible to plot the potential fields of the EEG onto models of the scalp. This plot ting of information as neuroimages followed the structural and functional techniques of Cf, MRI, PET and SPECf. The success of this method, which began in the early 1980s, has led to the brain mapping of EEGs and EPs being increasingly used for di agnosistic purposes in neurology, psychiatry and psychopharma cology. The pioneers of this method believed in it and were commit ted to its success. However, many traditionalists felt that it gave no new information and so regarded the method with scepticism. Some found both the coloured maps and the mapping technique misleading, which led to unnecessary conflict between mappers and their chromophobic oponents. Emotions have run so high that some professional bodies have justifiably adopted guidelines and warned of the misuse of the method.

Despite numerous reports of cerebral damage in cardiac surgery, the subject has not been given the attention it requires. This book, with a preface by Torkel Aberg, will remedy that situation. The causes and incidence of pre- and post-operative cerebral damage are considered in the first section. Cardiac surgery patients frequently have preoperative cerebral impairment, not suprising when one considers the impaired circulation from a damaged heart and the brain's prodigious need for blood. Moreover, several perioperative aspects of surgical procedures have been considered as possible causes of cerebral dysfunction, for example: microbubbles, toxic by-products, non-pulsatile blood flow. The second section describes how imaging techniques (CT scan, MRI, regional cerebral blood flow imaging), and functional assessment techniques. (PET scan, EEG, BEAM and evoked potentials) can be used to measure cerebral damage. In the third section, psychometric and neuropsychological techniques are used to assess impaired mental abilities (abstract thinking, language, memory, visuo-spatial ability, mental flexibility, attention and concentration). The final section explores the relationship between cerebral dysfunction and psychopathology (several types of depression, anxiety, and aspects of organic brain syndrome, delirium and dementia).
